Research Interest

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.

Current Research

Synthesis and Characterization of Iron Nanoparticles from Digested Iron from fly ash using two reductants

Research Details

Iron was extracted from raw coal fly ash material collected from Mpumalanga Province coal mine field using wet extraction method. The extracted iron was digested and used as ferric iron source for the synthesis of the nanoiron. Simple chemical precipitation method was employed using sodium borohydride (NaBH4) and hydrazine (N2H4). The nanoiron was characterized using analytical techniques such as X-ray diffraction (XRD) X-ray fluorescence (XRF), scanning electron microscopy (SEM), High resolution transmission electron microscopy (HRTEM), Bruanuer-Emmette- Teller (BET) surface area, and Fourier Transform Infrared (FTIR) spectroscopy. The XRD results identified magnetite for NaBH4 and goethite for N2H4 synthesized nanoiron. The SEM and HRTEM revealed spherical morphology for their nanoiron particles. In conclusion, iron extracted from coal fly ash can be used to make nanoiron particles.
