Sayed et al / Physical Chemistry 17(1) (2015) 1-5 2 materials and tablets. The results obtained by these methods were also compared statistically.

There are various methods for the analysis of Potassium Sorbate and Sodium Benzoate in food products, but a rapid and reliable method for identification of these preservatives in Doogh (an Iranian traditional dairy drink) is a procedure, in which high performance liquid chromatography (HPLC) utilized and followed by UV diode array detection of the two preservatives. The aim of this case study w...

Quantification of dissolved organic carbon (DOC) and iron (Fe) in surface waters is critical for understanding the water quality dynamics, brownification balance northern hemisphere. Especially remote areas, sampling laboratory analysis DOC Fe content at a sufficient temporal frequency difficult. Ultraviolet–visible (UV–Vis) spectrophotometry promising tool monitoring to increase applications r...

In this research, the dinuclear Zn(ii) complex of anthracene based tripodal tetramine Zn2L was synthesized, and its sensing abilities towards anions was investigated using the indicator displacement assay (IDA) approach with four complexometric indicators: pyrocatechol violet (PV), bromopyrogallol red (BPG), methylthymol blue (MTB) and xylenol orange (XO). UV-vis spectrophotometry results indic...

Under UV-visible light irradiation, multiple synergetic promotion effects on the photocatalytic activity of TiO2 by gold deposition can be observed, and plasmonic Au/TiO2 shows great potential for photocatalytic solar conversion.

The removal of water pollutants by photocatalysis is a promising technique, mainly due to its environmentally friendly and sustainable nature. In this study, the degradation recalcitrant organic pollutant, malachite green (MG), was investigated in microstructured silver oxide photocatalyst. (Ag2O) microparticles (MPs) were synthesized low-cost, method, mediated tea leaves extract. surface, morp...

This research was conducted to identify simplicia microscopically, phytochemical screening and determination of total flavonoid content extract ethyl acetate fraction from Moringa (Moringa oleifera L.) leaves using UV-Visible Spectrophotometry method. The experimental design used in this study perform microscopic identification leaf powder simplicia, make 96% 70% ethanol extract, then carry out...

Dates (Phoenix dactylifera L.) are a unique fruit because they have many health benefits. Ajwa dates one of the that people interested in for ingestion. Making date-infused water or nabeez is technique to ingest as exemplified by Prophet SAW and believed benefits digestion. As result, there has never been any research on analysis active compounds from water, particularly themselves, so goal thi...

modified bubble column extraction with ultrasonic bath (bce-ub) method was used to extract atropine from the stem and leaves of atropa belladonna. optimum condition were obtained with kamada solvent which was chloroform-methanol-ammonia 15:15:1(v/v/v) as extraction solvent, the particle size of  less than  350 µm, an extraction time of 23.95 min, a liquor to material ratio of 15.08 ml/g and  an...

In recent years, drug use is on the rise, causing environmental pollution. Therefore, control a common practice in many laboratories. This project focuses increasing method for determining small amounts of norfloxacin aqueous and biological samples. Solid-phase extraction samples using 2-aminopyridine/graphene oxide nano-plates visible ultraviolet spectrophotometric measurements are used These ...
