摘要
利用玉米芯对含Zn2+废水处理进行了研究。结果表明,玉米芯对Zn2+有较好的吸附效果。活化后的玉米芯粉对Zn2+的吸附比普通玉米芯粉效果更好。溶液的pH值在5左右,吸附时间为5h,活化玉米芯粉对Zn2+的吸附率可达93%以上。
The wastewater of Zn^2＋ was treated by corncob power. The results indicated corncob power are a good kind of sorbent of Zn^2＋. The activated corncob power has more strong adsorption to Zn^2＋ than natural corncob power. At pH value of 5 and residence time of 5h, the adsorption rate of Zn^2＋ by activated corncob power can achieve over 93%.
