Synthesis and Characterization of Indigenous Hydrophilized Polyvinylidene Fluoride Membrane for Drinking Water Purification: Experimental Study and Modeling Aspects
Indigenous polyvinylidene fluoride (PVDF) membrane was hydrophilized by blending with polyvinyl alcohol (PVA) which was further cross-linked with glutaraldehyde and tested for surface water purification. Synthesized membranes were characterized by SEM and FTIR to study the surface and cross-sectional morphologies and intermolecular interactions, respectively. The effect of parameters, namely feed pressure, operational time, and the cross-linking agent concentration on the process efficiency was studied.
Quantitative Determination of Ephedrine Hydrochloride in Pharmaceutical Injections by Highly Sensitive Turbidimetric and Reversed-Phase Combined with UFLC Methods
In this paper, turbidimetric and reversed-phase ultra-fast liquid chromatography (UFLC) methods were described for the quantitative determination of ephedrine hydrochloride in pharmaceutical injections form. The first method is based on measuring the turbidimetric values for the formed yellowish white precipitate in suspension status in order to determine the ephedrine hydrochloride concentration. The suspended substance is formed as a result of the reaction of ephedrine hydrochloride with phosphomolybdic acid which was used as a reagent.
Comparative Study of Moringa Oleifera and Citrus Paradisi as Disinfectants and Coagulants for Water Treatment
The coagulant and disinfectant qualities of Moringa oleifera and Citrus paradisi were investigated on various water samples acquired from sachet water (packaged water), borehole water, river water and well water. The results revealed that Moringa oleifera functioned adequately at settling time beyond 2 h in highly turbid river water but was more effective when combined with Citrus paradisi. Moringa oleifera or its combination with Citrus paradisi is less effective for turbid water treatment but effective for river water (sample) purification.
