Abstract
Dye removal from industrial wastewater is still a major challenge to this day. It is urged to find an efficient and economically feasible approach to remove dyes from wastewater before discharge. The use of hydrogels for dye removal has been proposed because of its high absorbing capacity and relatively low price. This work studies the dye removal behaviour of different hydrogels towards cationic and anionic dyes, by measuring the dye removal obtained through spectrophotometer techniques. The hydrogels investigated are Poly(2-Acrylamido-2-Methylpropane Sulphonic Acid) (PAMPS) hydrogels, commercial sodium polyacrylate (Na-PA), chitosan (CH), and different mixtures such as CH/PAMPS and CH/Na-PA, along with a semi-IPN P(AMPS/Na-PA). It was found that the negatively charged PAMPS hydrogel showed greater cationic dye removal, opposed to the positively charged CH which removed more anionic dye. Regarding the CH/PAMPS hydrogels, it had an impressive dye removal of for both cationic and anionic dyes, reaching 90% and 85%, respectively. It is concluded that the electrostatic interaction greatly influences the dye removal capacity. Hence, the design of hydrogel materials for dye removal purposes should take into consideration the electrostatic interaction of the dye with the hydrogel surface.
