The remediation of organic and inorganic pollutants from the aqueous environment has touched a certain level with the development of research. Environmental pollution is increasing day by day due to industrial activities which cause a negative effect on human health and the ecosystem. Nowadays, heavy metals have a special concern due to its toxicity, persistence and bioaccumulation in nature. Toxic metals like chromium, nickel, arsenic, lead, mercury, cadmium are the main contaminants of water because they are non-biodegradable in nature. Nickel is also a toxic metal, mostly used in industries because of its anticorrosion behaviour. As a consequence nickel is present in the wastage of electroplating, tableware, metal finishing, plastics manufacturing, nickel-cadmium batteries, fertilizers and mining industries and these waste have dangerous impact on the human health and environment and causes the diseases i.e. diarrhea, anemia, hepatitis, kidney damage, gastrointestinal distress, skin dermatitis, and central nervous system dysfunction. In the present review article, several techniques are discussed for the treatment of nickel from the industrial environment. The elimination of nickel from wastewater is not important only for economic purposes but also for environmental safety.
