Abstract: Removal of heavy metal cations of Cr3+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+ from simulated water due to nanomaterial-based gallium nitride nanocage (Ga5N10Nc) is the target of this research. Ga5N10Nc was modeled in the presence of heavy metal cations (Cr3+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+). The essence of covalent traits for these composites displays the equivalent energy and visibility of the partial density of states (PDOS) for the p states of nitrogen and d states of heavy metal ions of Cr3+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+ through water treatment. In other words, the chemical amendment twists the covalent bonding of functional groups on the backbone of the hybrid composite of gallium nitride towards a striking enhancement in the adsorption capacity parameter. In addition, the nuclear magnetic resonance (NMR) analysis suggested the substantial peaks surrounding metal ions of Cr3+, Mn2+, Co2+, Ni2+, Cu2+, and Zn2+ on the hybrid composite of gallium nitride during ion deletion from water. On the other hand, the selectivity of metal ion adsorption by a byhybrid composite of gallium nitride has been authorized as: Ni2+˃˃˃ Cu2+ ˃ Co2+˃ Mn2+ ˃ Cr3+ ˃˃ Zn2+. In this research, it is suggested that heavy metal ions adsorbed can be applied to amplify the optoelectronic properties of gallium nitride, which can be used to develop photoelectric instruments for water purification.
