Thermal and chemical modification of bentonite for adsorption of an anionic dye
Raw bentonite (RB), a known low-cost versatile clay was used as an adsorbent. RB was treated thermally and chemically to increase its adsorption capacity. For thermal treatment (TTB), the bentonite was heated at 400 °C for 60 min, and for the chemical modification, its surface was treated by cetyltrimethylammonium bromide (CTAB) to prepare organo-modified bentonite (CTAB-B). The removal of Cong...
متن کاملChemical modification studies on Ricinus communis (Castor Bean) agglutinin.
Ricinus communis agglutinin was subjected to various chemical treatments and the effect on its hemagglutinating and saccharide-binding properties was studied. Acetylation, succinylation and citraconylation led to a complete loss in the activity of the agglutinin, whereas reductive methylation had no effect on the activity, showing that charged amino groups were involved in the hemagglutinating ...
متن کاملSimultaneous adsorption of Cd2+ and reactive dye on mesoporous nanocarbons
High-surface-area mesoporous MgO-templated nanocarbons made with reinforcing fibres from scrap tyres and a bituminous waste as carbon precursor were employed for the simultaneous adsorption of Cd and reactive Cibacron Brilliant Yellow 3G-P dye. A commercial activated carbon (AC) Darco KB-WJ was also used for comparison purposes. The effect of the pH of the solution was studied to establish whet...
متن کاملAdsorption of Reactive Dye Using Agricultural Waste - a Kinetic Approach
This study was designed to investigate the removal of reactive violet 48 from wastewater using Commercial activated carbon and Coir pith activated carbon. Its adsorption capacity has been tested for the decolourization of waste water containing reactive violet 48. The effect of system variables such as concentration, temperature, contact time and pH were studied. The adsorption data follow Lang...
متن کاملChemical Modification of Polysaccharides Using Reactive Extrusion
Sodium carboxymethyl starch (CMS) was prepared using an extruder as a continuous solvent-less chemical reactor. The effects of NaOH, H2O, temperature, ethanol, sodium mono chloro acetate (SMCA), sodium tripolyphosphate (STPP), citric acid, epichlorohydrin and screw configuration on the degree of substitution (DS) and swelling properties of CMS were studied. Using these factors, CMS with the DS ...
