Heavy metal adsorption experiment on powder filter using zeolite and porous feldspar

Abstract

Isothermal and dynamic adsorption tests were conducted to evaluate the degree of heavy metal adsorption of the filter made of zeolite powder and zeolite and porous feldsapr mixture. As a result of isothermal adsorption experiments, Pb solution of 0.2~1000ppm, Cd solution of 0.02~1000ppm and Cu solution of 0.004~1000ppm were adsorbed 100% by A1 and A2 absbent materials. In the case of arsenic, using A1, the residual contents were 0.18, 5.17, 64.21 and 366.50ppm, respectively,when reacted with 1, 10, 100 and 1000ppm solutions. Most of the samples except arsenic were adsorbed within 10 minutes, and the A2 showed excellent adsorption performance.ion of 0.2~1000ppm, Cd solution of 0.02~1000ppm and Cu solution of 0.004~1000ppm were adsorbed 100% by A1 and A2 absbent materials.
