Abstract

Ever increasing industrialization has b een an important factor causing many environmental problems. Man made inputs asso ciated with industrial practices; mineral exploration, industrial processes and solid wa ste management contribute to heavy metal contamination of natural ecosystem. Nickel is one of the heavy metals that are present in industrial water from traces to very high quantity. Extraction of Ni 2+ from the effluents using flyash depends on various parameters such as pH, quantity of fly ash and sorption time of flyash. Laboratory investiga tions were carried out to optimize these parameters. Under these optimum conditions it was observed that 42% of Ni 2+ was removed by flyash.
