Researchers are in continuous search of better strategies to minimize, if not prevent, the anthropogenic release of toxic heavy metals, such as Cu(II) and Pb(II), into drinking water resources and the natural environment. Herein, we report for the fi

Publikováno v: Journal of Environmental Chemical Engineering. 5:5746-5753

In this study, the potential of groundwater treatment sludge reuse in the adsorption of nickel ions from aqueous solutions was evaluated. The effects of varying solution pH (4.5, 5.5, 6.5, 7.5), initial nickel concentrations (10, 50, 100, 200 mg L−
