| 摘 要： | 采用天祝褐煤中提取的腐殖酸对Cr(Ⅵ)进行了吸附性能的研究,确定了Cr(Ⅵ)的吸附平衡时间、pH值大小及吸附速率方程,讨论了腐殖酸用量和Cr(Ⅵ)初始浓度与吸附率、吸附量的关系。实验结果显示,吸附速率方程为V=0.046 69C,且当吸附时间为12 h,pH=5,腐殖酸用量为0.8 g,Cr(Ⅵ)初始浓度为350 mg/L左右时,腐殖酸对Cr(Ⅵ)吸附量达34.28 mg/g。

| Abstract: | The adsorption performance of humid acid from lignite in Tianzhu to Cr(Ⅵ) was studied.The adsorption time,pH value and velocity equation were determined.The dosage of humid acid and the initial concentration of Cr(Ⅵ) to adsorption quantity was discussed.The results showed that the velocity equation was V=0.046 69C,and when adsorption time was 12 h,HA dosage was 0.8 g,pH=5,and initial concentration of Cr(Ⅵ) was about 350 mg/L,the adsorption capacity was up to 34.28 mg/g. |
