The attempt on Chromium and Cyanide removing from industrial wastewater of chemical plotting was achieved by using the natural polymer ( animal gelatin 0 and calcium salts . Among three treatments with non treated wastewater , we were selected the treatment with calcium chloride and gelatin in which the chromium (Cr +6 ) reduced from 3.5 mg /l to 0.86 mg / l and the cyanide from 0.06 mg /l to 0.03 mg / l . The treatment with gelatin alone reduced concentration of the cyanide to 0.015 mg / l. Chromium adsorption in three treatments after two hours of stabling was ranged between 37 – 75 % and cyanide 30 – 75 % which became within the limitation.
