摘要
利用玉米芯对舍Cd2+废水处理进行了研究。结果表明,玉米芯对Cd2+有较好的吸附效果,活化后的玉米芯粉对Cd2+的吸附比天然玉米芯效果更好,溶液的pH值在7左右,吸附时间为2h,活化玉米芯粉对Cd2+的吸附率可达98％以上。
The wastewater of Cd^2＋ was investigated by corncob powder. The results indicated corncob powder was a good kind of sorbent of Cd^2＋. The activated corncob powder had stronger adsorption about Cd^2＋ than natural corncob powder. At a pH value of 7 and vibration time of 2 h, the adsorption rate of Cd^2＋ by activated corncob powder could achieve over 98 %.
