The adsorption behaviors of activated carbon powder and loess for zinc, copper and lead for each in aqueous solution by Batch test were studied. The important factors to get rid of heavy metal ions are to the amounts of adsorbent, reaction time of stiring, pH, temperature and ionic strengths. It has been shown that copper and lead appeared good adsorption efficiency under concentration of 10 ppm, also in case of zinc has 20 ppm. In general the more quantity of adsorbent increase, the more adsorption efficiency has. In case of reaction time among factors had nearly 100% remove copper and lead ions in aqueous solution in half of hour, but zinc had de-adsorption phenomenon passed 30 min. on the decreasing of adsorption efficiency. On the other hand the adsorption efficiency had increased in higher temperature. Also copper and lead in Alkali, Zinc ion in acidic part of pH range had a good adsorption efficiency. In last as the addition of strong electrolyte had not effect on adsorption efficiency at all. After all the best selectivity for carbon powder and loess were lead, copper and zinc in turn. Also loess has not good one to compare with carbon powder as the adsorbents, but the best adsorbent for zinc ion.
