| Abstract: | First, the author outlined the basic characteristic of some major zeolitic rocks in Shandong and then emphatically discussed on the exchange capacity of zeolite rocks and their effectiveness of exchange-adsorption of heavy metal (Pb, Hg, Zn, Cd, Cr, etc.) ions, and the influence of such factors as acidity and temperature of media, grain size and modification of the zeoltic rocks, exchange-adsorption time and flow rate of liquid on the results of exchange-adsorption of heavy metal ions. The mechanism and fav... |
