Synthesis of Zeolite using Fly ash and its application in Removal of Cu 2+ , Ni 2+ , Mn 2+ from Paper Industry Effluent

An improved synthesis for fly ash based zeolite has been attempted and studies have been carried out for the removal of Cu 2+ , Ni 2+ and Mn 2+ from paper industry wastewater. The parameters affecting adsorption process, such as initial pH, weight of zeolite, contact time were investigated. The transition metal ions present in the waste Cu 2+ , Ni 2+ and Mn 2+ shows better adsorption capacities on synthesized zeolite. The order of removal of heavy metal ions is Ni 2+ > Mn 2+ > Cu 2+ .
