Title: Properties of modified chitosan adsorb acid chrome blue K in wastewater
Abstract: Based on its adsorption, chitosan was made into adsorbent after chemical modification. The adsorption effect was studied that use this adsorbent to treat the acid chrome blue K wastewater, instead of printing and dyeing wastewater. In order to study the effect of decoloration, the pH, and temperature of acid chrome blue K wastewater, and the dosing of modified chitosan had been adjusted. The experimental results show that the decoloration rate of the treatment of acid chrome blue K wastewater with 10 mg/L initial concentration can reach to 98.97%, in the certain conditions of the solution: pH = 6, at 318 K, 0.10 g adsorbent, and adsorption time is 0.5 hour. In weak acid, after modification, chitosan can achieve a satisfying result in the treatment of decoloration of acid chrome blue K wastewater.
