After the reaction of succinic anhydride and chitosan,it was compounded with graphene oxide and finally reacted with ferrous chloride and ferric chloride to obtain Fe-GO-SAACS adsorbent.The adsorbents were characterized by IR,thermogravimetric analysis and SEM.Fe-GO-SAACS was used to investigate the adsorption of alizarin red and xylene orange by univariate method,desorption was conducted on the adsorbed saturated Fe-GO-SAACS,and the recycling property of regeneration was explored.The results showed that the dosing quantity of the best adsorption for alizarin red and xylenol orange were 0.1g,best adsorption initial concentration were 300mg·L-1 and 200mg·L-1,respectively.The best adsorption temperature was 65 ℃,the best adsorption time was 80min,and best adsorption pH=9.The adsorbent can desorption under alkaline condition.Fe-GO-SAACS adsorbent can adsorb organic dyes in wastewater of printing and dyeing industry.
