The awareness of the chemical composition of our environment is very important because crucial changes in the chemical makeup of an environment are enough to trigger outcomes that could lead to population decline and loss of biodiversity. My expertise in the area of analytical and environmental chemistry and health is being used to address various issues of environmental significance and development of new methods to solve lingering environmental pollution and environmental health problems. New analytical methods have been developed in the area of separation science for the analysis of nanomaterials-based compounds that have been found useful in some industrial applications bringing important addition to the level of the existing knowledge on the materials.
Other areas of my research is the employment of the principles of green chemistry in the processing of samples for analysis, to this end I have developed or improved on existing methods for extraction and cleanup of organic pollutants, such as phthalate esters, organochlorine pesticides and polycyclic aromatic hydrocarbon compounds from environmental and biological samples. The methods significantly reduced the volume of hazardous organic solvents utilized in the process without compromising the quality of the results.
The use of locally-sourced agricultural biochar as an alternative low-cost absorbent for dispersive solid phase extraction absorbent (d-SPE) in the clean-up steps determination of organic contaminants, such as phthalate esters, pesticides residues and polycyclic aromatic hydrocarbons (PAHs) in samples with complex matrixes, such as milk, is being exploited to obtain inexpensive material as a replacement for the conventional, but expensive, synthetic absorbents such as graphitized carbon black (GCB), octadecyl (C18) and primary secondary amine (PSA).
In the area of renewable energy, especially in the production of biodiesel, my research has proffered an alternative pathway for processing the oilseeds of non-edible oils with high free fatty acids (FFA) and our findings have led to a significant reduction in the FFAs contents of the oils without the need to go through the cumbersome and expensive after-extraction processes like degumming or dewaxing. The application of these procedures industrially will boost the potential of using non-edible oil for large-scale biodiesel production.
