A study was performed to evaluate capability of aquatic macrophyte Eichhornia crassipes plants to combat oxidative stress caused by tannery effluent treatment. For this purpose, tannery effluent was collected from “Up flow Anaerobic Sludge Blanket” (UASB) Jajmau, Kanpur. Plants of Eichhornia crassipes were exposed to various concentrations of tannery effluent (0.0, 25, 50, 75 and 100%) for 2 an...

The toxicity of Cu to Daphnia magna was investigated in a series of 48-h immobilization assays in effluents from four wastewater treatment works. The assay results were compared with median effective concentration (EC50) forecasts produced by the HydroQual biotic ligand model (BLM), the refined D. magna BLM, and a modified BLM that was constructed by integrating the refined D. magna biotic liga...

The objective of this study was to explore the extent of mineralization of Biodigester Effluent (BDE) by Electrochemical Treatment using aluminum electrodes in monopolar configuration. The benefit of determining a COD/TOC ratio is becoming evident. While both parameters are useful independently, the ratio of the two values, and the fluctuation of this ratio, is an excellent indicator of the org...

pharmaceutical industry is currently undergoing a transient phase with new orientation. loss of financial resources, presence of new therapeutic agents and increasing cost of research and development have called for a full.scale restructuring within the pharmaceutical industry to retain even the most basic competitiveness. the development of new technologies has been as one way out of the dilem...

Simple, specific, accurate and precise method, namely, reverse phase high performance liquid chromatography was developed for estimation of duloxetine HCl in pharmaceutical formulations. For the high performance liquid chromatography method, Phenomenox C-18, 5 μm column consisting of 250×4.6 mm i.d. in isocratic mode, with mobile phase containing 0.01M 5.5 pH phosphate buffer: acetonitrile (60:...

Background & Aims of the Study: Pharmaceutical wastewater is one of the major complex and toxic industrial effluents that contain little or no biodegradable organic matters. Materials & Methods: In this study, H2O2/UV base advance oxidation process (AOP) was used to remove organic materials from pharmaceutical industry effluent. Experiments were conducted for the chemical...

A simple and reliable high performance liquid chromatography method was developed and validated for the rapid determination of cyclosporine A in new pharmaceutical dosage forms based on the use of poly (methylvinylether-co-maleic anhydride) nanoparticles. The chromatographic separation was achieved using Ultrabase C18 column (250×4.6 mm, 5 μm), which was kept at 75°. The gradient mobile phase c...

A simple stability indicating reversed-phase HPLC method was developed and subsequently validated for estimation of Cefpirome sulphate (CPS) present in pharmaceutical dosage forms. The proposed RP-HPLC method utilizes a LiChroCART-Lichrosphere100, C18 RP column (250 mm × 4mm × 5 μm) in an isocratic separation mode with mobile phase consisting of methanol and water in the proportion of 50:50 % (...

Emerging contaminants (ECs) are chemical compounds commonly present in water. It is only recently that this family of compounds is being recognized as significant water pollutants (Czech and Ribinowska, 2013). ECs include a wide variety of chemicals such as pharmaceutical and personal care products (PPCPs), pesticides, hydrocarbons and hormones, among others, that once released into the environ...

Hardwood KP bleaching effluents, before (influent) and after (effluent) biological treatment, were characterized and compared to identify the main bio-recalcitrant organic compounds in the effluent. The results indicate that biological treatment reduces CODcr and BOD5 by 67% and 88%, respectively. However, various bio-recalcitrant organic compounds were still retained in the biologically-treate...
