The adsorption difference of Pb2+ and Zn2+ in sandstone and breccia of Pb-Zn Mine of Yunnan Prov ince was studied by using modem 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 obey s Freundlich experiential formula. The value of 1/n on the adsorption Pb2 and Zn2+ in sandstone hardly has any difference.but the value ofk differs observably. The adsorption process ofZn2+ or Pb2+ in sandstone or breccia from solution is fraetal-like. The kinetic equation of adsorption is lgp = k alg t or Q = abt( 1 + bt) -1 and the values oflg k. a. and D of breecia are bigger than those of sandstone at 30 and 50 ℃. These parameters decrease basically with the increase of tempture.The adsorption capacity of Pb2+ is almost equal in sandstone and breccia, but the adsorption ability of Zn2+ in breeciais stronger than that in sandstone.
