A Review on the Application of Biosorption in Removal of Nickel from Aqueous Solutions

Abstract

Biological uptake nickel by living, inactive, microbial or plant-derived biomass is an alternative and innovative technology to remove this contaminat from aqueous solutions. It has high adsorbency and readsorption capacity. In this study, with the aim of introducing different types of microbial and plant-derived biological adsorbents in order to remove nickel from aqueous solution and revealing the adsorption capacity of each adsorbent, articles published between 2001 and 2020 were used. The results of research works performed were used to compare the adsorption capacity of microbial and plant-derived biosorbents to remove nickel from aqueous solution. Studies showed that the skin uptake capacity of grapefruit with 95% is more favorable than other plant derivatives. Curtobacterium sp also has the best performance with 100% adsorption capacity among microbial biosorbents. Research showed that the use of these biomasses, as a biological adsorbent, for the removal of nickel in aqueous solution is a promising and environmentally friendly prospect.
