This work investigated sorption properties of diethylenetriamine derivative of chitosan (CTSN) for removal of acid dyes (Acid Green 25 (AG25), Acid Red 18 (AR18) and Acid Orange 10 (AO10)) from aqueous solutions. Sorption kinetics was firstly evaluated. It was found that pseudo-second-order model fits well with these dyes adsorbed on CTSN. Compared with normal chitosan, CTSN has higher capacity for AR18 and AO10, but a lower value for AG25. Mechanisms and interactions of dyes with CTSN were also discussed by study the effect of pH, influence of hydrogen-bonding and comparing the sorption capacities.

The capability of sawdust for removal of Reactive Yellow (RY 1) and Acid Orange (AO2), from aqueous solutions was studied. The effect of various experimental parameters such as different treatments of sawdust, sorbent dose and pH of solution were studied. The saw dust a relatively abundant and inexpensive material was found to be effective absorbent for the removal of reactive and acid dyes from their aqueous solutions. It was found that the sawdust activated with acid have higher adsorption capacity. It has been found that at initial pH of 2 and at higher sorbent dose reactive and acid dyes were removed more effectively. Key words: Sawdust; Adsorption; Dye removal; Sorbent dose.
