Abstract:
Objective To study the adsorption performance of chitosan in printing and dyeing wastewater treatment.Methods The influence factors such as chitosan concentrations(0-500 mg/L),pH value(1-13),temperatures(20-50 ℃)and time(0.5-2.5 h) were considered in the test.Results When the concentration of chitosan was 200 mg/L,pH value was 2-5,time was 0.5 h and at the room temperature,the absorption could show a good result.The deeolorizing rate could reach above 90%.Conclusion The chitosan concentrations,pH value,time and temperature affect the adsorption performance of chitosan in printing and dyeing wastewater treatment.
