| Summary: | 碩士 === 義守大學 === 材料科學與工程學系 === 93 === This thesis was forcus on studying adsorption characteristic of heavy metals onto spent activated clay（SPAC）. Five metals,Cu, Ni, Zn,Pb,Cd were used as absorbate. Parameters that may be affected the adsorption including, solution pH, ionic strength, metal concentration, and temperature were conducted.
Experimental results showed that the SPAC treated by coffee machine. Exhibited in a higher adsorption capacities than that of the SPAC without treated. Results also showed both increasing pH and temperature could increase the adsorption. However, as experimental condition was controlled at low ionic strength, the adsorption capacity was decreased according. The result,also demonstrated as changing the testing conditions including, heavy metals concentration, the pH, the temperature, the ion intensity , all can have the different influence to its removing rate.
