摘要: A possibility of using clay waste rocks (shales) from coal mines in the removal heavy metals industrial wastewaters is considered this paper. Raw and calcined (600 °C) shales accompanying beds two Polish were examined with respect to their adsorptive capabilities for Pb, Ni Cu ions. The mineralogical composition was determined TG/DTG analysis carried out. granulometric compositions raw compared. Tests adsorption various Pb(II), Ni(II) Cu(II) concentrations conducted pH before after analyzed. results indicate that both differ particular metal calcination improved lead, but worsened them nickel. have good capabilities, could be used as inexpensive adsorbents ions, especially regions where resources shale are easy accessible form spoil tips.
