    Decomposition of Bis(N-benzyl-salicydenaminato)zinc (II) Complex for the Synthesis of ZnO Nanoparticles to Fabricate ZnO-Chitosan Nanocomposite for the Removal of Iron (II) Ions from Wastewater by Thokozani Xaba, Patli Phillia Mongwai, Mahadi Lesaoana

    Published 2019-01-01
    “…The preparation of bis(N-benzyl-salicydenaminato)zinc (II) complex and the synthesis of zinc oxide nanoparticles via the thermal decomposition of zinc complex together with the fabrication of ZnO-chitosan nanocomposites for the removal of iron (II) ions from wastewater is reported. The optical properties of the synthesized nanoparticles showed band edges that are red-shifted in wavelengths when the decomposition temperature was increased. …”
