Paper Title:
Removal of Trivalent Chromium ION in Wastewater by Zeolite 4a
  Abstract

Under the static condition, researching zeolite 4A to the chromium ion's adsorption characteristic, discussing the influence of different adsorption factors. The results indicated that: When the wastewater temperature was 30°C, at pH 3-4,adsorbed 30min,dosing 3g/L of zeolite 4A adsorption chromic wastewater(100mg/L), the chromium ion elimination rate may reached above 99%. At the same time, the zeolite 4A conforms to Langmuir and the Freundlich isotherm to the chromium ion's adsorption, the correlation coefficient respectively was 0.9997 and 0.9753, obtained the zeolite 4A to the chromium ion saturated adsorptive capacity was 50.25mg/L.Obviously, zeolite 4A as a new inorganic ions exchange material for the treatment of chromic wastewater, has the broad prospects for development.
