摘要
以0.1g磺化腐植酸为吸附剂,在30°C恒温振荡下对水中Cr(VI)进行吸附,用可见分光光度法测定吸附前后水中Cr(VI)的含量。结果表明,Freundlich模型能够很好地用于描述磺化腐植酸对Cr(VI)的吸附,且当溶液pH在1.8左右,吸附时间为150min时,磺化腐植酸对Cr(VI)的吸附率可达99%以上。
Cr（Ⅵ） in a simulated electroplating wastewater was adsorbed with 0.1 g sulfonated humic acid as adsorbent at 30 ℃. The content of Cr（Ⅵ） was determined by visible spectrophotometry after adsorption. The results showed that Freundlich equation fits the adsorption. Under the optimal conditions of pH 1.8 and adsorption time 150 rain, the adsorption rate of Cr（Ⅵ） by sulfonated humic acid is above 99%.
