摘要
Abstract
This paper studied adsorption removal of D301 resin and activated carbon for bromate ion,established the standard curve of dimethyl yellow-spectrophotometric method for measuring the concentration of bromate,and analyzed the effects of nitrate ion,chloride ion,humic acid and sulfate ion on adsorption. The results show that the concentration of bromate standard curve equation is y =1. 709 9x + 0. 076 7,with linear range being 0 ~ 12 μg/ 10 mL,R2 being 0. 999 7. Adsorption performance of D301 resin is better than that of activated carbon,with adsorption capacity being 20. 7 mg/ g and 18. 8 times than that of activated carbon. Four kinds of interference ions impact the adsorption performance of D301 resin in different degrees,and greater with higher concentration.关键词
