A study of the modified diatomite prepared by the PAM coated on the surface of the raw diatomite and applied to treat the simulated wastewater with intensive concentration of lead ions [Pb(Ⅱ)]. Pb(Ⅱ) has been considered as one of some significantly toxic heavymetals (Cd,Cr,Pb, Mn,Cu,Zn,et al) contaminated the surfacewaters. The results indicated that modification could enhance the diatomite and acidic heavymetal wastewater’s compatibility; Obtained that modified diatomite’s saturated adsorption capacity could reach 66.15~ 68.95mg/g, superio...
