吸附法去除低温水体中的磺胺类抗生素
Removal of Sulfa Antibiotics in Low Temperature Water by Adsorption Method
摘要
Abstract
In view of the water environment pollution caused by the use of the antibiotics in livestock and poultry breeding,we studied the removal effects and influencing factors of natural mineral materials (volcanic cinder)and resources transformation materials (bone black and fungus chaff)to the adsorption of four kinds of sulfa antibiotics: sulfathiazole (ST ), sulfamethyldiazine (SM), sulfamethazine (SM2)and sulfamethoxazole (SMX).The results show that the adsorption effect of three kinds of materials is in the order of fungus chaff>volcanic cinder>bone black.When the mass concentration of four kinds of antibiotics is 5 mg/L in the water,the adsorption rate of fungus chaff is more than 80%,and the adsorption capacity is 1.60 mg/g.The adsorption rates of volcanic cinder and bone black which modified by the mass fraction of 10% Al2 (SO 4 )3 are more than 60%,and the adsorption capacity is more than 0.24 mg/g.The best adsorption pH value is 4—6,Fe3 + ,Mn2 + , NH 4 + ,Cl- ,solidity and alkalinity have a great influence on the adsorption of sulfa antibiotics by fungus chaff.关键词
