Anion sensing is a dynamic research field due to the biological and environmental importance of some organic or inorganic anions. Hydrazones show promising properties in design anion chemosensors presence proton donor acceptor sites their structure. In this work, two novel dinitrophenyl hydrazones, functionalized with quinoline moiety, were synthesized characterized by spectroscopic spectrometr...

A specific class of anions inhibit creatine kinase by stabilizing the dead-end complex, enzymedivalent cation*ADP*creatine (Watts, D. C. (1973) The Enzymes 8, 383-455). The inhibitory action o? the anions is attributed to the ability of the anions to mimic the equatorial PO3 plane formed by the migrating phosphoryl group in the transition state of the reaction. Infrared spectroscopy has been us...

5-Hydroxy-2-methylfurfural (HMF) has a high derivatization potential and is considered the sleeping giant of biobased platform chemicals. It accessible by acid hydrolysis various carbohydrate-containing feeds, preferably those in fructose content. We here report detailed study on use thick juice, an intermediate sucrose (SUC)-rich stream sugar factory, pure SUC for synthesis HMF batch reactor s...

The liver fulfills many vital functions for the body, among them bile formation and detoxification. Bile salts are organic anions, major constituents of at high concentrations cytotoxic. Detoxification exposes to harmful compounds. This function is therefore potentially damaging liver. Impaired may lead hepatic accumulation subsequently disease. Diagnosis diseases involves measurement so-called...

In this paper, the quantum chemistry calculations related to the structural parameter of the chromite and molybdate anions and the complexes obtained from them with the glycine and alanine amino acids were performed. The calculations were carried out using HF and DFT methods and in the base series 6-31G *. Thermodynamic studies related to the formation of complexes have been considered and thei...

The current study was attributed to uranium (VI) ions adsorption using a anion exchanger resin, Dowex®2x8, in the presence of sulfate anions. Evaluation of operational parameters including contact time, pH, initial concentration of uranium ions, and presence of various anions (including phosphate, sulfate, chloride, fluoride, and nitrate) in the solution was assessed on sorption performance of ...

The present article reviews the use of polyethylene glycol (PEG) or polyoxyethylene (POE) as the stationary phase for the separation of inorganic anions in ion chromatography and discusses about the retention mechanisms involved in the separation of anions on the novel stationary phases. PEG permanently coated on a hydrophobic stationary phase retained anions in the partition mode and allowed ...
