Abstract: Chromatography is one of the most commonly used methods to separate molecules of various sizes. The technique is frequently applied to the separation of proteins. Such biotechnical applications require effective tools to predict the chromatographic process in order to avoid tedious and costly laboratory experiments during process development. In this thesis, the use of experiments as well as mathematical models to achieve this goal is demonstrated.:.......

Abstract: Two new ligands derived from 2-aminophenol have been prepared. The first ligand (boron compound) L1 was prepared by refluxing one mole of sodium borohydride with two mole of 2-aminophenol in a mixture of methanol: acetone (2:1) .The second ligand (Schiff base) L2 was prepared by refluxing equimolar from 4-bromoacetophenone and 2-aminophenol in methanol: acetone (2:1). Cu (II) and Pt (IV) complexes of ligands have been also prepared. The ligands and their metal complexes were characterized by elemental analysis, molar conductivity and spectral studies of FTIR, 1H,13CNMR, thermal analysis, UV-VIS, as well as atomic absorption and magnetic susceptibility of metal complexes. All prepared compounds were tested as antibacterial agents against gram negative bacteria (E-coli)and gram positive bacteria (Staphylococcus aureus).
Keywords: Aminophenol, boron compounds, Schiff bases.

Abstract: Kinetics of the Ni(II) catalysed oxidation of glycylglycine by alkaline KMnO4 has been studied spectrophotometrically over the range 2.0 ≤ 103[Gly-Gly] ≤ 6.0 mol dm-3; 1.25 ≤ 107[OH-] ≤ 10.0mol dm-3; 293 ≤ T ≤ 313 K and I = 0.5 mol dm-3 (KNO3). The reaction exhibits first order in [MnO4-]T and [Ni(II)]T but fractional order in both [Gly-Gly]T and [OH-]Trespectively. The rate of reaction is found to increase with increase in [Gly-Gly]T and [OH-]T.For uncatalysed reactionΔH#(kJmol-1) and ΔS# (JK-1 mol-1) are found to be44.4 ± 1.8 and -182 ± 6.0respectively but for Ni(II) catalysed reaction, the parameters ΔH# (kJ mol-1) and ΔS# (JK-1 mol-1) are found to be 23.46 ± 2.53 and -159.1 ± 8.43 respectively.:.......

Abstract: Teak is more considered as a major constituent in many of the traditional medicines. The proximate composition and amino acid analysis was carried out on deffated Tectona grandis seed meal. The proximate composition showed the following values; protein 42.0%, ash 7.00%, CHO 41.5%, crude fibre 3.30%, crude fat 1.00% and moisture content 5.20%. The amino acid content showed that glutamate and aspatate have the highest concentrations with 23.6 and 12.2 g/100g respectively while the lowest concentrations were recorded for tryptophan and methionine with 0.806 g/100g and 0.889 g/100g respectively. Protein content of the seed meal was found to be acidic as total acidic amino acid (TAAA) is more than total basic amino acid (TBAA).

Abstract: A new fatty chain derivative of quinazolinone has been synthesized from the two simple precursors of 2-amino benzoic acid and palmitoyl chloride. The novel quinazolinone derivative is obtained via the nucleophilic interaction of 2-palmitoyl-4H-1, 3-benzoxazine -4-one with thiosemicarbazide that yield 2-pentadecyl-quinazolinylthiourea (PQT). Newly synthesized compound was identified via spectral methods; their [FTIR, 1H-NMR and 13C-NMR] and measurement of some of its physical properties. Furthermore the inhibition effect of synthesized compound on the corrosion of carbon steel in 2N HCl was studied by potentiodynamic polarization. Morphology of the carbon steel was examined using scanning electron microscopy (SEM) in presence and absence of inhibitor.

Abstract: The kinetics of oxidative decolorization of metanil yellow (MY) by Bromamine -B in NaOH medium in presence of OsO(IV) has been investigated spectrophotometrically (λmax = 414 nm) at 298 K. Kinetic studies were performed under pseudo first-order conditions of [BAB]o>> [MY]o. The reactions show first-order dependence each on [BAB]o, [MY] and [OsO(IV)], a fractional-order dependence on [NaOH]. Stoichiometry of the reaction was found to be 1:3 and the oxidation products were identified by spectral analysis...:.......

Abstract: Ground water is increasingly being sought as a source of drinking water due to the scarcity, non-availability and bacteriological pollution of surface water. Ground water is a major source for all purposes of water requirements in India and it plays a vital role to human life and economic activity. The occurrence and distribution of ground water in the country varies significantly depending on geology, rainfall and geomorphology. The unplanned and non-scientific development of ground water resources has led to sharp depletion of the resources and also degradation of quality at many places.:.......

Abstract: An efficient method was developed for the simultaneous determination of sunset yellow and carmoisine in soft drink samples by high performance liquid chromatography (HPLC-UV-Vis). Affecting parameters on separation and detection of the dyes were investigated and optimized. Mixture of acetate buffer pH=6.7 and acetonitrile with ratio 78:22 as mobile phase; flow rate 1.0 ml/min and detection wavelength of 500 nm were selected as optimum values. For these dyes good linearity (0.25–50 mg L-1, >r2=0.99) were obtained. Limits of detection for both of the dyes were 0.1mg L-1..:.......
