Abstract

Amino functionalized graphene oxide was synthesized (AFGO) using a chemical method in order to apply in ion flotation process as a novel nanocollector for nickel ion removal with the aim of reducing collector consumption during the process. The synthesized AFGO was investigated using various analytical analysis. To create the negative charge onto the amino functionalized graphene oxide, 2,6-diaminopyridine was used to improve the properties of amino functionalized graphene oxide for removal of nickel ions with positive charge from synthetic wastewater using ion flotation. This study introduced a new collector for ion flotation to reduce the required collector concentration during the process which had simple synthesis, economical, high efficiency and stability in a wastewater. The nickel removal percentage of approximately 100% was achieved using the nanocollector.
