    1. Abstract In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…

    Adsorption isotherm models : To study the proper model, the isotherm data were analyzed and were fitted them into two models, Freundlich and Langmuir, because they are the most suitable and employed models. Equilibrium uptake of CV and MB was investigated with sorbent weight of 0.5 g of fennel seeds in contact with 100 mL of solutions and at pH 4 for CV and 6 for MB. The flasks were shaken at 200 rpm and the equilibrium concentration of the remaining CV and MB was determined by spectrometer.…

    TLC and HPTLC Introductions Thin layer chromatography (TLC) is derived from liquid chromatography where liquid serves as mobile phase and thin layer of substance on a flat late surface serves as stationary phase. The thin layer of materials act as sorbent while the mobile phase known as solvent. Solvent will send the solutes through the sorbent depends on the strength of the mobile phase as it dissolved the solute and send them up the plate against gravity ,and resistance of sorbent…

    The 1HNMR of chloro (pyridine) cobaloxime (III) showed all the characteristic peaks of the product. It had very few peaks and is very tidy. This shows that the molecule has high symmetry. The large singlet peak at 2.5ppm, corresponds to the 4 methyl groups that are connected to the double bond N of the dimethylglyoxime. It integrates to 12 H’s. These methyl groups are accounted for at a higher ppm that usual. This could be due to the fact they are doubly bonded to the electronegative Nitrogen…
