摘要
以石油焦为原料 ,采用KOH活化法制取高比表面积活性炭。考察了高比表面积活性炭吸附废水中Cr(VI)时 ,pH值、Cr(VI)浓度、吸附时间和活性炭用量等因素对Cr(VI)吸附量和废水中Cr(VI)残余浓度的影响。实验结果表明高比表面积活性炭在适宜条件下对Cr(VI)
The petroleum coke was used as raw material to prepare activated carbons high specific surface area by KOH activated method. The obtained activated carbons were used as adsorbent to adsorb Cr(VI) in aqueous solution. The effect of pH value, concentration of Cr(VI), adsorption time and dosage of activated carbon on absorption capacity of Cr(VI) and residual concentration in aqueous solution had been investigated systematically. The results show that high specific surface area activated carbon has excellent absorption capacity and could easily be regenerated under the suitable absorption conditions.
