Batch adsorption experiments were carried out for
the adsorption of cationic dye from aqueous solution onto
composite activated carbon. The composite activated carbon was
prepared from brewer’s spent grain and sea bean shell at a ratio
of 1:1. The equilibrium studies were done at different
concentrations and temperatures. The equilibrium data were
fitted to Langmuir, Freundlich, Dubinin-Radushkevich, and
Temkin isotherm models. The results showed that both Lagmuir
and Freundlich isotherm model fitted the data reasonably well
but Freundlich isotherm fitted better in the temperature range
studied. This confirmed that the adsorption is heterogeneous,
non-specific and non-uniform in nature. Kinetic studies were also
undertaken in terms of first order, second order, pseudo first
order, pseudo second order, Elovich, Boyd, and intra-particle
diffusion models. The results indicated that the data followed
pseudo second order model with surface adsorption and intraparticle
diffusion concurrently operating during the adsorbateadsorbent
interaction. The values of the thermodynamic
parameters computed from Van’t Hoff plot confirmed the
process to be endothermic and spontaneous in nature.
— Processes based on immobilized enzymes have been studied extensively in the last few decades and today are also applied to the safeguard of environmental parameters. In this work, zeolite composite flat membranes with different chemical composition, transition metal, and microporous structures were prepared using in situ and secondary growth crystallization synthesis methods in/on stainless steel porous disks. All zeolite materials were been used in catalase adsorption to analyze the zeolite behavior andthe effect of chemical composition and structure on interaction with the enzyme. This study shows that the electrostatic type of interaction seems to be of the utmost importance in influencing immobilization, while the zeolite Brönsted acidity of the support is the subordinate parameter, which differentiates the adsorption performances of different zeolite structures (that distinct for chemical composition of the framework). Moreover, it permits to conclude that transition metal-containing membranes adsorb a higher percentage of the enzyme with respect to no-exchanged membranes and that, for all materials synthesized, the amount of catalase adsorbed onto the zeolite crystals and membranes increases with the temperature.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. METHODS OF DETERMINING MECHANISM OF REACTION
1)Identification of products
2)Determination of presence of intermediate
3)Study of catalysis
4)Labling studies
1. Group labling
2. Isotope labling
3. Crossover experiments
5) Sterio chemical study
6) Kinetic studies
7) Kinetic isotope effect
4. CROSSSOVER EXPERIMENTS
1) Non- kinetic method of determining mechanism of a reaction
2) Nature of INTER MOLECULAR (or) INTRA MOLECUAR
rearrangement can be determined by CROSSOVER
EXPERIMENTS
3) Two Simiar but Non-identical reactants are used in crossoer
experiments.
4) If the product of the reaction contains the fragments of both
reactants the product is crossover product and so the product is
inter molecular rearrangement.
9. INDUSTRIAL EXAMPLE
Inverse vulcanization is a copolymerization of elemental sulfur and alkenes that
provides unique materials with high sulfur content (typically $50% sulfur by mass).
These polymers contain a dynamic and reactive polysulfide network that creates
many opportunities for processing, assembly, and repair that are not possible with
traditional plastics, rubbers and thermosets. In this study, we demonstrate that
two surfaces of these sulfur polymers can be chemically joined at room
temperature through a phosphine or amine-catalyzed exchange of the S–S bonds
in the polymer. When the nucleophile is pyridine or triethylamine, we show that
S–S metathesis only occurs at room temperature for a sulfur rank > 2—an
important discovery for the design of polymers made by inverse vulcanization.
This mechanistic understanding of the S–S metathesis was further supported with
small molecule crossover experiments in addition to computational studies.
Applications of this chemistry in latent adhesives, additive manufacturing,
polymer repair, and recycling are also presented.
