The adsorption difference of Pb2’ and Zn2 in sandstone and breccia of Pb-Zn Mine of Yunnan Province was studied by using modern instrument analysis method and fractal geometry theory. The results show that the adsorption capacity (Q) of Pb2+ in this two rocks is bigger than that of Zn2+, and Q in various initial concentration solutions obeys Freundlich experiential formula. The value of 1/n on the adsorption Pb2+ and Zn2+ in sandstone hardly has any difference, but the value of k differs observably. The adsorption process of Zn2+ or Ph2+ in sandstone or breccia from solution is fractal-like. The kinetic equation of adsorption is 1gp=k-alg t or Q=abt(1 ± bt) -1,and the values of 1g k, a, and D of breccia are bigger than those of sandstone at 30 and 50 ℃ These parameters decrease basically with the increase of temperature. The adsorption capacity of Pb2+ is almost equal in sandstone and breccia, but the adsorption ability of Zn2+ in breccia is stronger than that in sandstone.
