Atomic absorption technique is used to determine losartan potassiumthrough the quantitative detection of potassium (K) element in drug.the extraction was carried out by acid digestion and percentagerecovery 97.2%, error percentage -2.8, limit 0.038 μg/ml, relative standard deviation did not exceed 2.58%. The resultswere compared with UV-Visible method 96.5%, 0.93 μg / ml relativestandard more t...

The present study focused on the structural, morphological, optical and fluorescence properties of Ni0.5?xMg0.5CuxFe2O4 (x = 0.0, 0.1, 0.3 0.5) nanoparticles synthesized by using auto combustion technique. structural formation ferrite were confirmed FTIR spectroscopic study. From spectra nanoparticles, metal ions are situated in two different sub lattices i.e. tetrahedral (A-site) octahedral (B...

BACKGROUND The blackcurrant (Ribes nigrum L.) is a species of native currant which contains a lot of polyphenolic antioxidants which is used medicinally and has a fundamental role in the maintenance health. MATERIALS, METHODS AND OBJECTIVE: Ultraviolet-visible spectrophotometry and ultraviolet range high performance liquid chromatography (HPLC) were used to characterize the polyphenolic content...

The polyherbal extract based lozenges include Viola odorata L, Cordialatifolia L, Menthapiperita L., Adhatodavasica, Glycyrrhizaglabra, Piper longum, Hyssopusofficinalis, Alpiniagalangal which is envisioned for c...

gabapentin is an anticonvulsant widely used in the treatment of epilepsy.an accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. this is a simple, accurate, precise, selective and visible spectrophotometric method. the method is based on the measurement of drug absorbance as a result of yellow solution format...

The visible-light response is a necessary condition for titanium dioxide (TiO2) photocatalyst to function as visible light active photocatalyst. This can be solved by investigation of the bandgaps and optimization doping levels multivalency metal-doped TiO2. In this study, pure Cu, Fe, Ni-doped TiO2 photocatalysts were prepared sol‐gel method. characterized using XRD, FTIR, FESEM, EDX, N2 physi...

Layered double hydroxides (LDHs) are an ultravioletlight (UV)-resistant material. In this study, two types of LDHs (Mg-Al-LDHs and Zn-Al-LDHs) were applied to modify bitumen by melt-blending. The effect of ultraviolet aging on the rheology and chemistry of LDH-modified bitumen was studied by means of dynamic shear rheometer (DSR), thin-layer chromatography with flame ionization detection (TLC-F...
