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...

The paper presents an examination of the possibility applying raspberry flower extract (Rubus idaeus L.) as a green inhibitor general corrosion copper in 3% NaCl. Raspberry flowers sort Polka were collected from Moševac near Maglaj city, Bosnia and Herzegovina. ethanol was obtained by ultrasonic extraction. A significant content polyphenol found UV/VIS spectrophotometry analysis. Results DC tec...

ETHODS FOR DETERMINATION of deuterium oxide (D00) using infrared spectrophotometry have been reported by a number of workers (1-3). These methods permit determination of D00 in biologic fluids with an accuracy and precision satisfactory for determination of total body water and similar problems. The use of an infrared spectrophotometer for measurement of 1)20 in water and biologic fluids offers...

This study was performed to determine whether extracellular silver nanoparticles (AgNPs) production is a genus-wide phenotype associated with all the members of genus Morganella, or only Morganella morganii RP-42 isolate is able to synthesize extracellular Ag nanoparticles. To undertake this study, all the available Morganella isolates were exposed to Ag+ ions, and the obtained nanoproducts wer...

The effectiveness and usability of a diffusion tube for air quality sampling were assessed at 14 sites throughout an oil gas production area in Atrush sub-district measurement Sulfur dioxide (SO2) nitrogen (NO2) ambient by Palmes tubes during autumn winter season 2021-2022. Using triethanolamine as trapping agent, the passive sampler collects SO2 NO2, which are then proven to be sulphate nitrit...

In this study, zero-, first-, secondand third-order derivative spectrophotometry methods were developed for the determination of metoprolol in pharmaceutical preparations. In zero order spectrophotometry, absorbance values were measured at 276 nm in zero order spectra of solution of metoprolol in methanol in the range of 240-310 nm. In first derivative spectrophotometry, absorbance values were ...

BACKGROUND Paraquat (PQ) is a world-wide used herbicide and also a type of common poison for suicide and accidental poisoning. Numerous studies have proved that the concentration of serum PQ plays an important role in prognosis. Spectrophotometry, including common spectrophotometry and second-derivative spectrophotometry, is commonly used for PQ detection in primary hospitals. So far, lack of s...
