Removal of Basic Blue 3 from the aqueous solution with ternary polymer nanocomposite: Swelling,kinetics,isotherms and error function

Ternary nanocomposite (gum arabic / pva / alginate) adsorbent was prepared by a cost effective method for dyes removal,because gum arabic and alginate are the cheapest materials. gum arabic is a natural gum. alginate that has long carboxylate functional group is a biosorbent. in this study,gum arabic/pva/alginate was prepared that this absorbent has the high specific surface area. bet was measured as 12.93 m2/g. swelling of adsorbent was determined at different ph. for the maximum swelling ratio was obtained at ph 6.88≅7,adsorption experiments were studied by the batch method. freundlich,bet and langmuir isotherm methods were applied at different concentrations and constant temperature 25°c. finally,the adsorption capacity of the nanocomposite was calculated as 200 mgg-1. the different adsorption kinetic models were studied at temperature from 25°c to 45°c and different concentrations. the thermodynamic parameters as δh°,δg°,and δs° were calculated. © 2017,chemical society of pakistan. all rights reserved.
