Topic: Physicochemical Characterization Of Used Carbide And Ash Materials Collected From Automobile Mechanic Workshop
Description: Introduction: The indiscriminate disposal of carbide ash waste by automobile industries have created serious problem to the environment because it affects man and the ecology of their vicinity. Aim: is to investigate the quantity, quality and application of calcium carbide and its waste ash generated by the automobile industries.Methodology: the raw and carbide ash samples were characterized using analytical technical such as X-ray diffraction XRD , X-ray fluorescence XRF , scanning electron microscope SEM and Fourier transform infrared FTIR spectroscopy. The results of the X-ray diffraction XRD identified Portlandite, Litharge and Hematite mineral phases in raw Carbide while Portlandite and Calcite mineral phases for both carbide ash waste 1 CAW1 and carbide ash waste 2 CAW2 . Expected Results: the XRD will help to identify the mineral phases present in both materials, XRF elemental analysis will reveal the chemical compositions of raw carbide A and carbide ash B , the IR spectrum in all the samples indicative of the functional groups present in each sample. The SEM will reveal the morphology or shapes of the raw carbide and carbide ash generated from the automobile industry. Contribution to knowledge/society: This research will help to determine the chemical composition of the samples and application in the making of cement and plaster of Paris, and how it can be used to treat textile dye effluent.

Synthesis of Zinc Oxide and it s Composite Zinc Oxide Nanoparticles
Nanoparticles are products of a rapidly growing technology with small particle size that are very reactive are widely applied in many fields. Unfortunately the use of toxic organic solvents and strong reducing agents are not environmental friendly which results in producing hazardous wastes that pose a great threat on the environment. The aim of this study is to synthesize zinc oxide nanoparticles ZnO NPs and composite ZnO nanoparticles CZnO NPs . The ZnO NPs samples would be assessed to determine their material qualities. Chemical precipitation method was used to synthesize ZnO NPs and composite ZnO NPs. The synthesized ZnO NPs and composite ZnO NPs were characterized using analytical techniques such as Fourier Transform Infrared spectroscopy FTIR , Scanning electron microscopy SEM , X-Ray Diffraction XRD , X-Ray Fluorescence XRF and Thermogravimetric analysis TGA . EXPECTED RESULTS: The XRD results should reveal the mineral phases in pulverized cassava leaves, composite ZnO NPs and ZnO NPs. SEM morphology reveal the transformation in process of synthesis. The FTIR results showed the absorption bands of functional group stretching and bending which indicate the presence of some functional groups with their characteristic peaks. The XRF results revealed elemental composition of the pulverized leaves, synthesized ZnO and Composite ZnO nanoparticles. The TGA results showed thermal stability of the pulverized leaves, synthesized ZnO and composite ZnO nanoparticle samples at high temperature. In conclusion, the quality of synthesized ZnO NPs and its composite ZnO NPs would be assessed.
