Utilization of groundwater treatment sludge and sludge-derived manganese dioxide for the removal of nickel ions from aqueous solutions

Groundwater treatment sludge contains manganese components that are unutilized and disposed along with the rest of the solid waste. In this study, the potential of groundwater treatment sludge reuse in the adsorption of nickel ions from aqueous solutions was evaluated. Results showed that the pH lev...
