The physico-chemical properties of water and sediments therein were analyzed for assessing the suitability of Siddheshwar dam (India) waters for irrigation purpose. The physical parameters include total dissolved solids and electrical conductivity. The chemical parameters studied include pH, free carbon dioxide, total hardness, calcium hardness, magnesium hardness, phenolphthalein alkalinity, t...

UV curable PUA resin was successfully synthesized from polyol based on sustainable resource originated from itaconic acid (IA), isophorone diisocyanate (IPDI) and 2-hydroxyethyl methacrylate (HEMA). A polyol was synthesized by condensation reaction of IA with 16-hexanediol in the presence of p-Toluenesulfonic acid (pTSA). The synthesized PUA resin was characterized for its structural elucidatio...

Objective: To develop and validate simple, rapid, precise, accurate, and economical UV spectrophotometric and reverse phase high performance liquid chromatographic methods for the estimation of alogliptin benzoate (AGP). Methods: UV spectrophotometric method was performed using UV/Vis double beam spectrophotometer with a spectral bandwidth of 1 nm and 1.0 cm matched quartz cells. The maximum ab...

In this study, iron nanoparticles (FeNPs) were synthesized by green route under microwave irradiation. Terminalia arjuna bark extract was used for synthesis, which acts as reducing and stabilizing agent. The synthesized FeNPs were characterised by UV-Visible spectra, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectra (FT-IR), BET surface are...

recent research highlights the importance of gsts in the establishment of chronic helminth infections. gsts have the potential to protect the parasite against the host immune response. in this present study, gst enzyme assay has been investigated on whole extract of f. hepatica and sheep liver tissue. to the 1-ml plastic cuvette, added 200 mm potassium phosphate buffer. then added 50 mm gsh red...

The objective of this study was determining the heavy metal contents in sediment along the coastlines of Hormuzgan province. Sediment constitutes are important part of aquatic ecosystems. They provide habitat for benthic organisms and could be a significant sink as well as a potential source of contaminants. Three sources of heavy metals pollution in this area are industry, natural mineral...

Thin film of zinc oxide was prepared by spin coating on pyrex glass using zinc acetate dehydrate, 2-methoxyethanol and monoethanolamine (MEA) as a precursor, solvent and stabilizer respectively. Also, Aluminium-doped thin film of ZnO was prepared by using AlCl3. Deposited thin films were investigated for structural and optical properties using X-ray diffraction (XRD) and UV–VIS-NIR spectrophoto...

A simple, specific, accurate and stability-indicating UV- Spectrophotometric method was developed for the estimation of candesartan cilexitil, using a Shimadzu, model 1700 spectrophotometer and a mobile phase composed of methanol: water in the ratio of 9:1 at wave length (λ(max)) 254 nm. Linearity was established for candesartan in the range of 10-90 μg/ml. The percentage recovery of was found ...

Nano-sized ZnO was synthesized through the hydroxide precipitation using drop wise method. The variations in resistance of sensing pellet at different temperatures were recorded. The relative resistance was decreased linearly with increasing temperatures over the range, 150°C-260°C. The activation energy of ZnO calculated from Arrhenius plot was found 0.007eV. Temperature response in terms of t...

The determination of total iron in pharmaceutical products and natural waters as Fe(II) using a sequential injection system was investigated. A cadmium reductor consisting of cadmium granules was used to reduce Fe (III) to Fe (II). The Fe (II) was then determined (by its reaction with 1,10 Phenanthroline ) as a [Fe(phen)3 ] complex at 515 nm with a UV/Vis spectrophotometer. The linear range of ...
