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

Abstract EN

The whole world is faced with a huge challenge of the shortage of clean water due to industrialization and the intimidation of climate change.

Poor water quality distresses many areas of human’s well-being.

Although there are existing technologies for water treatments, many of these methods utilize toxic substances which create more problems into the environment.

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.

The XRD patterns displayed the hexagonal ZnO phase for the synthesized nanoparticles.

TEM images revealed spherical-shaped particles which became agglomerated when the temperature was increased.

The parameters such as pH, contact time, and initial concentration were investigated during the water treatment.

The pH = 6 was found to be optimum, and the highest percentage removal was recovered after three hours for both adsorbents.
