The Department of Chemistry have hosted a doctoral dissertation defense entitled: Synthesis and Characterization of Some Selenazone Complexes and Nanoadsorbent Surfaces From Industrial Waste For Removing of Carcinogenic Dyes and Heavy MetalsFrom Water.
The thesis discuses using a new method to prepare 1,5-Diphenylselenocarbazone nanoparticles. and its complexes with ions of lead, cadmium, cobalt and nickel using hot methanol solvent. The compound and its complexes were characterized by using FT-IR, UV-Vis, 'H-NMR, C13-NMR, X-ray diffraction (XRD), EI-mass spectrometry, scanning electron microscopy (SEM), and thermal analysis (TG/DTA), measurements of Molar conductivity and FAAS flame atomic absorption measurements.
Also, the study has discused the preparation of adsorbent surfaces by reacting the selenazone compound with silica gel, graphene oxide and iron oxide. The prepared surfaces were characterized by using the a bove techniques.
The prepared surfaces were used to remove some dyes and toxic elements from the water, which showed excellent efficiency for their removing.
