Heated in water bath, uranyl ion and nitrate radical adsorbed on resin are replaced into solution by sodium bisulfate, then are determined by titanous method and spectrophotometry, respectively.
The results showed that the activation of sodium sulfide to the smithsonite due to the HS- ionadsorbed on the smithsonite's surface and lead to the zeta potential drop.
结果表明,硫化钠对菱锌矿的活化作用主要通过HS-吸附在菱锌矿表面,降低菱锌矿表面电位实现;

CO2 can be adsorbed on the surface of loess and laterite forming carbonate ion, and further produce great impact on heterogeneous reaction.
