| Abstract: | The crude zeolite powder was mixed with a combustible powder.The mixture was changed into particle materials by extrusion and a kind of porous zeolite particle adsorbent by high temperature calcination.This adsorbent was used to adsorb Cr~(3 ).The effect of pH,time and initial concentration of Cr~(3 ) on adsorption reaction were investigated,respectively.The adsorption isotherm drawn by the test data approximately fitted in Freundlich adsorption isothermal equation. |
