Feasibility study of mtbe physical adsorption from polluted water on gac, pac...eSAT Journals
Abstract MTBE or Methyl Tertiary Butyl Ether is an organic compound, which is used to increase the gasoline Octane Number. At the beginning of 80’s, by discovering the undesirable effects of tetra ethyl lead usage in fuel, MTBE started to be used worldwide. But gradually the undesirable effects of MTBE on environment had been revealed. There are many technologies for MTBE removal from polluted water. Adsorption is the most conventional and economical technology. In this research, some experiments have been done for studying the adsorption of MTBE on different solid adsorbent in batch process. In these experiments a fixed amount of adsorbents including Granular Activated Carbon (GAC), Powdered Activated Carbon (PAC) and the Husk Rice Carbon (HRC) have been put in different one litter covered vessels containing water polluted with known initial MTBE concentration and stirring them. By measuring MTBE concentration in the vessel at different times the effect of different operating parameters such as temperature and pH have been studied on adsorption and optimum condition have been determined. The batch experimental results have been used to calculate the constant parameters of Freundlich and Langmuir adsorption isotherm equations for these systems. Keywords: MTBE, Adsorption, Activated Carbon, Husk Rice Carbon

Removal of Harmful Textile Dye Congo Red from Aqueous Solution Using Chitosan...IJERA Editor
Color is an important aspect of human life. Textile industries are the major consumers of dye stuffs. During coloration process, 10 to 15 percent of the dyes will be lost and this will be discharged with the effluents coming from textile industries. These are very difficult to degrade and they may degrade to form products that are highly toxic to human. Today, methods such as coagulation, flocculation, activated carbon adsorption, etc. are available for the removal of dyes. These are all quite expensive and difficult to degrade. Chitosan is a natural hetero polymer derived from chitin. Chitosan has proved to be effective in removing hazardous compounds from environment due to its multiple functional groups. It is available as flakes and powder. In the present work, chitosan beads were prepared and modified with a cationic surfactant CTAB for the removal of dye Congo Red. Batch experiments were conducted to study the effect of CTAB concentration, contact time, agitation speed, adsorbent dosage, initial dye concentration and pH. Batch equilibrium data were analyzed using Langmuir and Freundlich isotherm. Bach kinetic data were analyzed using Pseudo first order kinetic model and pseudo second order kinetic model.
Toxic Trace Metals in Edible Oils by Graphite Furnace Atomic Absorption Spect...PerkinElmer, Inc.
"This method reports the development of a direct analysis
method for edible oil samples using GFAAS without digestion.
The advantages of using this method include small sample
volume, direct introduction of samples, high sensitivity, and
rapid analysis times. The application of GFAAS to arsenic,
lead and cadmium analysis in edible oils was performed.
The optimal pyrolysis and atomization temperatures, limit of detection, quality control (QC) checks and recoveries were studied in order to develop a rapid and accurate method.

Pyroligneous Liquor Produced at Different Heating Rates in Pyrolysis of Eucal...CrimsonpublishersMCDA
The objective of this research was to analyze the influence of two different heating rates (2.67 °C/min, 0.67 °C/min), reaching 500 °C as final temperature in pyrolysis, on the chemical composition of the pyroligneous liquor produced. Three pyrolysis sessions were performed for each heating rate on Eucalyptus urograndis wood chips in an oven-muffle connected to a gas-collecting system. The gravimetric yield was calculated, and the chemical compounds of pyroligneous liquors were identified through gas chromatograph-mass spectrometer. Heating rates did not affect the gravimetric yield of final products. However, qualitative differences were observed in the chemical composition of pyroligneous liquors produced. The presence of 1-hidroxy 2-propanone, 4-methylphenol (p-cresol), and 5-hidroxymethyl 2-furaldehyde compounds was detected only in the pyroligneous liquor produced at the highest heating rate (2.67 °C/min).

Multi-Element Determination of Cu, Mn, and Se using Electrothermal Atomic Abs...IOSR Journals
Simultaneous multi-element graphite furnace atomic absorption spectrometer (SIMAA 6000) is used to get a new multi-element determinations methodology for Cu, Mn, and Se. Firstly, the optimum conditions for single-element mode are determined (which include: pyrolysis and atomization temperatures). Secondly, the optimum conditions for multi-element mode are also determined. The conditions in the two modes have been compared in terms of the characteristic masses, detection limits and pyrolysis and atomization temperatures. The effect of the matrix on the determination has been studied using urine standard sample from Seronorm (LOT 0511545). The accuracy of the developing methods has been confirmed by analysis different biological reference materials. Simultaneous multi-element GF-AAS offers a rapid, low cost and sensitive method for the analysis of trace elements
