“DEVELOPMENT AND VALIDATION OF STABILITY INDICATING METHOD FOR SIMULTANEOUS ESTIMATION OF CEFTRIAXONE AND TAZOBACTAM INJECTION USING RP-UPLC METHOD” 2.1 OBJECTIVE To develop and Validate Stability Indicating Method for simultaneous estimation of Ceftriaxone and Tazobactam in their combined dosage form by RP-UPLC method in various stress condition like, alkaline, acidic, oxidative, thermal and photo degradation. 2.4 METHODOLOGY 2.4.1 Chromatographic Condition Column Separation was achieved by…

in the liquid phase according to the radical mechanism produced by MEC as the intermediate and acetic acid as the final product. Mice and acetic acid (0.2: 1.0 mass ratio) are obtained by non-oxidizing liquid phase oxidation at 1800C and 53 bars with remixing. Continuous oxidation under the flow conditions of components at 1500C, 65 bar and the stay time of 2-7 minutes constitute MEK and acetic acid by 3: 1 mass. This process has a slight economic advantage over the removal of 2-butanol. But the…

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,…

Lactate dehydrogenase was assayed according to the method of King (1965) [21]. Reagents required: 1. 0.1 M glycine buffer: 7.5 g of glycine and 5.85 mg of sodium chloride were dissolved in one litre of distilled water. 2. Buffered substrate: 2.76 g of lithium lactate was dissolved in 125 ml of glycine buffer containing 75 ml of 0.1 N sodium hydroxide solution. This was prepared just before use. 3. 0.4 N NaOH. 4. 5.0 mg of NAD+ was dissolved in 1.0 ml of distilled water just before use. 5.…

Freezing salt-water experiment Contents: Contents, introduction and literature review on page 1. Aim, hypothesis, variables, risk assessment, materials and method on page 2. Results on page 3. Discussion and conclusion on page 4. Introduction: I have decided to do my SRP on salt water freezing because our planet is 71% water and about 96.5% of it is in the ocean which it is salt water so this is why I was interested in seeing how much salt, depresses the water from freezing. Literature…

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.…

Ecology Research Laboratory are the authors of Acid Rain and its Ecological Consequences, a review addressing the issue of acid rain precipitation. The article hypothesizes, “Acid rain is one of the most serious environmental problems emerged due to air pollution” (Agrawal & Singh, 2008). It was assumed that humans have harnessed and utilized different natural resources for their individual benefits from the onset of civilization to the present day. In turn, acid rain has become a major…
