| Abstract: | Heavy metals are harmful to human body,it is difficult to removal from wastewater,using cheap adsorbent effectively to removal heavy metal ions is both economical and environmental.Bentonite which is cheap,high spicific surface and adsorptivity is a kind of natural mineral adsorbent.The absorption mechanism of bentonite on heavy metals was analyzed.At the end,the existing problems in the disposal of heavy metal wastewater with modified bentonite and research directions were put forward. |
