The document summarizes research on the translocation of insecticides in trees after trunk injection. Two tests were conducted using different injection methods and products on various tree species. The first test found that Arboprof moved abnormally while Arbocap moved too slowly. Arborjet translocated rapidly but stopped after 5 hours. The second test found that translocation stopped 2 days after injection for all products. This could be due to degradation or absorption of the organic coloring hiding further movement of the active ingredient. More testing is needed.

The document describes research into the decolorization of Reactive Violet 5 dye by Stenotrophomonas maltophilia using anthraquinone-2-sulfonate as a redox mediator. The objectives were to optimize conditions for efficient dye decolorization and determine quinone reductase activity. Experiments showed that maximum decolorization occurred with 2 mM AQS, 0.05% glucose and yeast extract, 20 mM KNO3 at pH 7.5 and 37°C. Increased quinone reductase activity in the presence of AQS and dye suggested its role in dye reduction. Thin layer chromatography confirmed degradation of the dye.

Lawrence Thesis (Master)
This document summarizes research on using aerobic granular sludge to treat wastewater from azo dyes. Aerobic granular sludge was cultivated and its ability to simultaneously remove color and degrade aromatic amines through anaerobic and aerobic processes was investigated. The effects of granule size, dissolved oxygen, biomass concentration, and organic loading on treatment performance were evaluated. Under optimized conditions, over 60% equivalent dye removal and 80% removal of color and aromatic amines were achieved within 48 hours. Future work may focus on controlling granule size and applying the process to real textile wastewater.
Abstract ACM
This document summarizes a study on using coconut shell charcoal to remove dyes from textile wastewater through adsorption. The researchers modified the charcoal surface using sulfuric acid and sodium hydroxide, and chemically activated it using the same chemicals. They characterized the raw and modified charcoals. Adsorption studies using patent blue and acid red 88 dyes found the modified charcoal had higher adsorption capacity. Kinetic data fitted a pseudo second order model. The surface modified charcoal showed additional functional groups that improved adsorption capacity for removing dyes from wastewater.

Homogeneous Photocatalytic Degradation of Acid Alizarin Black Using Hydrogen ...Haydar Mohammad Salim
This document summarizes research on degrading the acid dye Alizarin Black using hydrogen peroxide and UV light (UV/H2O2). The research aims to study how the degradation of Alizarin Black is affected by dye concentration, hydrogen peroxide concentration, and pH. Results showed that degradation was most effective at a dye concentration of 100 mg/L and increased with higher hydrogen peroxide amounts. Degradation was also favored under neutral conditions compared to acidic or basic conditions. Kinetic studies found pseudo-first order degradation rates increased with higher hydrogen peroxide volumes and decreased with higher dye concentrations.Use of titanium dioxide photocatalysis on the remediation
This study investigated the photocatalytic degradation of two azo dyes found in textile wastewater using titanium dioxide (TiO2) photocatalysis. The effects of TiO2 concentration, UV irradiation time, solution pH, initial dye concentration, and hydrogen peroxide concentration on degradation were examined. Optimal conditions for highest degradation rates were determined. Results showed that complete decolorization of solutions could be achieved using an efficient photocatalyst under suitable operational parameters.

Banana peels as adsorbent, purify water by using banana peels
Banana peels have potential as a low-cost adsorbent for water purification. They contain acids and other molecules that can attract and bind to heavy metals and toxic compounds in water, removing contaminants similarly to more expensive industrial adsorbents. Experiments showed banana peels effectively removed heavy metals like copper and lead from water, as well as dyes, and performed as well or better than technological alternatives. As an agricultural waste, banana peels provide a renewable option for communities lacking water treatment infrastructure.

Multi-Stage Activated Biological Process (MSABP™)
The MSABP is a multi-stage attached growth biological wastewater treatment process that effectively treats pollutants without generating waste sludge. It utilizes naturally occurring microbial food chains where organisms that break down organics are consumed by higher-level organisms, removing them from the system. The process is made up of multiple treatment stages with different microbial environments, fixed film media, aeration, and controls to achieve high pollutant removal with minimal excess sludge. It has been successfully used to treat municipal and industrial wastewater.
Pesticides registration brazil 2012
The document outlines Brazil's pesticide registration process, which involves evaluation by three ministries - MAPA, ANVISA, and IBAMA. Registration involves obtaining a temporary registration (RET) and then conducting laboratory and field studies over 1-2 years. The technical product must demonstrate chemical equivalence and undergo toxicological evaluation. Additional studies may be required before the formulated product can be registered, which involves efficacy, toxicological, residue, and ecotoxicological studies overseen by the respective ministries. A consulting company called ProRegistros can assist with navigating the registration steps and requirements in Brazil.

This document summarizes a study that used a continuous stirred bed reactor (SBR) to treat textile wastewater through bacterial decolourisation. A mixture of three bacterial strains - Sphingomonas paucimobilis, Bacillus sp., and filamentous bacteria - were introduced to the SBR. The study used a mixture experimental design to optimize the formulation of bacterial strains and assess colour and COD removal. The results found that the highest predictable decolourisation and COD removal rates were 86.72% and 75.06% respectively. Regression analysis showed excellent correlation between the bacterial mixtures and responses of decolourisation and COD removal.
Campanella2017
This document describes a new method for rapidly determining nitrate levels in vegetables using gas chromatography-mass spectrometry (GC-MS). Nitrate is extracted from vegetable samples in hot water and converted to a volatile derivative called EtONO2 using simple aqueous chemistry. This derivative is separated from the vegetable matrix as a gas and analyzed by GC-MS. The method uses an isotopically labeled internal standard for quantification and can determine nitrate levels between 10-10,000 μg/g with a detection limit of 2 μg/g and precision of 1%. Analysis time is only 1.8 minutes, making this a fast and accurate technique for nitrate analysis in vegetables.

The document discusses using a fluorescence-based sensor called Fluoralys to monitor food processing and predict contaminant formation. The sensor uses spectroscopy methods to non-destructively analyze food samples with minimal contact. Chemometrics are then used to decompose the fluorescence data and extract factors related to contaminants. Case studies on monitoring acrylamide in potato chips and furan/phenols in carrot puree show the sensor can be calibrated to predict contaminant levels and optimize food processing conditions to minimize them while maintaining quality. The Fluoralys sensor provides a sensitive, rapid, and universal technique for both process monitoring and contaminant assessment in various foods.
