Ibuprofen (IBU), a nonsteroidal anti-inflammatory drug, is one of the most widely used and frequently detected pharmaceuticals personal care products in water bodies. This study examined IBU degradation aquatic solutions via ferric ion activated peroxydisulfate (PDS) coupled with electro-oxidation (EC/Fe3+/PDS). The mechanisms involved three synergistic reactions EC/Fe3+/PDS system, including: ...

To obtain a suitable oxidation method for removing the color and lowering the chemical oxygen demand (COD) of waste soy sauce, Fenton (Fe2+), Fenton-like (Fe3+), and ozone (O₃) oxidation methods are used as the target reactions. In experimental conditions for Fenton oxidation, the dose of Fe2+ and Fe3+ was varied between 100 mg/L and 300 mg/L. The dose of hydrogen peroxide for the reaction was ...

1. The preparation of potassium l-serylglycine O-sulphate and the corresponding (35)S-labelled ester is described. 2. Intraperitoneal injection of potassium l-serylglycine O[(35)S]-sulphate to rats results in about 75% of the radioactivity of the dose appearing in the urine within 48hr. Almost 72% of the radioactivity recovered in the urine was in the form of inorganic [(35)S]sulphate. 3. Analy...

novel ceramic oxides have been increasingly focused in recent years because of their potentialapplications in environmental purification especially to treat organic contaminants present in water. in thisresearch work, a set of nio-co3o4 nano-ceramic composite materials were prepared by a simple refluxcondensation method using nickel acetate / cobalt acetate as precursor salts, sodium monododecy...

this experiment was conducted to investigate the effects of different levels of creatine and protein in diets on performance and meat quality of broiler chickens. a total of 320 day old ross broiler chicks were used in a 2×4 factorial arrangement of dietary treatments comprised two levels of protein (ross recommendation and 10% higher than recommendation) and four levels of creatine (0, 0.1, 0....

Introduction. Different ferric and ferrous iron preparations can be used as oral iron supplements. Our aim was to compare the effects of oral ferric and ferrous iron therapies in women with iron deficiency anaemia. Methods. The present study included 104 women diagnosed with iron deficiency anaemia after evaluation. In the evaluations performed to detect the aetiology underlying the iron defici...

The regulation of the expression of the rus operon, proposed to encode an electron transfer chain from the outer to the inner membrane in the obligate acidophilic chemolithoautroph Acidithiobacillus ferrooxidans, has been studied at the RNA and protein levels. As observed by Northern hybridization, real-time PCR and reverse transcription analyses, this operon was more highly expressed in ferrou...
