Manganese (Mn) is one of the most abundant metals in Earth's crust. Manganese is present in ground water as a divalent ion (Mn2+) and is considered a pollutant mainly because of its organoleptic properties. It is an essential metal for the human system and many enzymes are activated by manganese. Therefore, manganese has to be removed from some waters and wastewaters for various reasons. Conventional chemical and physical treatments for Mn (II) removal from contaminated effluent consist of precipitation, depth filtration, ion exchange, adsorption and oxidation. The adsorption technique has been found to be one of the most effective for the removal of metal ions from solution. This review focuses on preparation of adsorbent by using of low cost material to remove manganese from wastewater.

Abstract


Manganese (Mn) is one of the most abundant metals in Earth's crust. Manganese is present in ground water as a divalent ion (Mn2+) and is considered a pollutant mainly because of its organoleptic properties. It is an essential metal for the human system and many enzymes are activated by manganese. Therefore, manganese has to be removed from some waters and wastewaters for various reasons. Conventional chemical and physical treatments for Mn (II) removal from contaminated effluent consist of precipitation, depth filtration, ion exchange, adsorption and oxidation. The adsorption technique has been found to be one of the most effective for the removal of metal ions from solution. This review focuses on preparation of adsorbent by using of low cost material to remove manganese from wastewater.
