The study of red alizarin remove in waste water by synthesized zeolite A

Zeolites are a important compounds for removal of harmful compounds in environment[1] . red alizarin is on of important cancer agent in chemical industrial waste water[2,3] . in this article studied adsorption of red alizarin in waste water by zeolie A(ZA) . ZA synthesized by mixing sodium alumina and sodium silicate solutions in 80oc at 48h in Teflon reactor. Then washed with water and ethanol and dry in 15oc . synthesized zeolite added in 100ml ammonium chloride 0.1M at 72h , then leaching and put in electric furnace at 4h and 450oc . them washed with water and dry in 100oc . XRD spectrum showed ZA and SEM picture showed particle size of ZA to 300-500nm . Then prepared 15ppm red alizarin solution and read uv adsorption in spectrophotometer and 500nm . added 20mm for that to 1g ZA in Teflon trough and shaker along of 8 hours and 6 degree . then readied adsorption result in 500nm and 6,12,18,24,30,36,48 and 54h . result was showed reduction 95% of red alizarin solution by ZA and all parts studied by SEM and IR .
