IX. RESEARCH (a) Completed Fatty acids, amines and amino acids are of immense importance. Some fatty acids are known precursors of the biologically important prostaglandins. Some other aliphatic amines and polyamines which are odorous substances are known precursors of the carcinogenic and toxic N-nitrosamine, while amino acid is the building blocks of proteins. The ability to monitor these groups of compounds is very important and several techniques to detect or confirm their presence are needed. A number of analytical methods have been used for their analysis ranging from classical to instrumental methods. However, each of these methods has its limitation and its disadvantages. Classical methods of analysis have the disadvantage of low sensitivity of detection, non-selectivity and non-specificity. The limitation of the classical approach has been overcome by modern chromatographic techniques in particular gas chromatography and high performance liquid chromatography. Gas chromatographic determination of amines at low concentration is hampered by adsorption and decomposition, column ghosting phenomena, tailed elution peaks and low detector sensitivity. To different degrees, one or more of these problems are encountered in the analysis of carboxylic and amino acids using any of the available chromatographic techniques.

A general approach to these problems has been the preparation of suitable derivatives of the analytes because derivatisation can be used to improve the chromatographic behavior as well as the sensitivity and 5

specificity of detection. Most derivatisation approaches in chromatographic analysis has been the use of solution reagents, in which the derivatising reagent is present in solution and mixed with a solution of substrate of interest (homogenous derivatisation). A major drawback of homogenous derivatisation is associated with the need to remove excess of reagent because the reagent often has similar behavior to the derivatives in terms of its response to the chromatographic detection. Therefore, the response of the system to their derivative may be swamped by that of the excess reagent. This problem of excess reagent is one that could be conveniently overcome if derivatisation was done in heterogeneous medium using solid- phase reagent.

So, in my research work, I have successfully developed, prepared, and applied some solid -phase reagents; made up of resin-bound N- nitroso- benzylsulfonamide, resin bound naphthalene methanol, resin bound bisulfate addition compound of salicylaldehyde and solution reagent comprising sodium benzoxazole-2- sulfonate for analytical derivatization of some fatty acids (acetic-, valeric-, hexanoic. Octanoic-, nonanoic- , capric-lauric-, palmitic acids) and some primary and secondary amines (ethylamine, propylamine, butylamine, diethylamine, di-n propylamine and di n-butylamine). The work has been concluded and published (see papers 1, 2, 4, 7, 8, 9, 20)

In Progress: Development of bound reagent i.e. Solid-Phase reagent (S-P reagent) for Endocrine Disrupting Compounds (EDCs), hydroxyl compounds (alcohols). Previous workers have employed solution reagents for chemical derivatisation of these functional group to produce fluorescent derivatives. One of the frustrating disadvantages of solution reagent is due to close similarity in the spectra of fluorescent characteristics of the reagent and the derivatives it forms with these analytes. The inevitable presence of excess reagents in the reaction mixture causes high background response and hence an inadequate detection limit for the analytes. Introduction of steps to remove excess reagent often makes the method more tedious and more prone to error. In my present study, S-P reagents for some analytes (EDCs, antibiotic metabolites, hydroxyl compounds) are developed. For instance, in developing a S-P reagent for alcohol my idea is based on the high reactivity of 2-pyridyl esters of thiocarboxylic acids with alcohol in the presence of silver ion (Ag+). An initial stage of this reaction was the preparation of 2-mercaptobenzoxazole, followed by quarternisation of the heteocyclic nitrogen through alkylation; thereafter, the S-P reagent was prepared merely by stirring with cationic ion exchange resin. The reagent was applied in this form to derivatise alcohol to produce derivative that fluoresced intensely. This study has become very important because it offers the opportunity to develop new method for trace analysis of ECDs (bisphenol A, triclosan and phthalates) in clinical and environmental samples. Results of the study are being processed for publication. My research work also continues with analysis of heavy metals and newly emerging environmental contaminant like poly brominate diphenyl ethers using both concentrated-based approach and risk-based approach. Some publications arising from this work are highlighted in papers 15, 17, 18, 19, 22, 23, 24, 31, 36, 37, 38, 39, 40 and 46.A research project involving evaluation of strategies for controlling aflatoxin contamination in grains (Maize, Beans, Millet) and groundnuts is on-going.
