Core-level photoelectron spectroscopy measurements have been performed of aqueous solutions of NaCl codissolved with NaClO(n) (n=1-4). Each species has a distinct Cl 2p electron binding energy, which can be exploited for depth-profiling experiments to study the competition between Cl(-) and ClO(n)(-) anions for residing in the outermost layers of the solution/vapor interface. Strongest propensi...

Combined disinfection with UV radiation and sodium hypochlorite was applied in disinfection the effluent after secondary treatment of hospital sewage. The inactivation effect of different combination modes and sequences of UV and sodium hypochlorite was studied. The contrast experiments of disinfection effect and the levels of residual chlorine were conducted by adding different dosage of sodiu...

The kinetics and mechanism of oxidation of L –Ascorbic acid by permanganate ion in acidic medium have been studied at 25±1°C, I = 1.0 mol dm (NaClO ), [H ] =1x10 mol dm .The stoichiometry was observed 3 + 2 3 4 to be 2:5 in terms of mole ratio of permanganate ions and ascorbic acid consumed. The reaction shows dependence on acid concentrations and is first order in both the oxidant and the redu...

In our study, the transformation of two most widely used UV filters, benzophenone-3 (BP3) and benzophenone-4 (BP4), in chlorinated water with disinfection reagents sodium hypochlorite (NaClO) and trichloroisocyanuric acid (TCCA) was studied. Based on the HPLC/MS and UV-Vis analysis the formation of two different chlorinated products (5-chloro-2-hydroxy-4-methoxybenzophenone and 3,5-dichloro-2-h...

The thermal energy conversion of natural gas (NG) using appropriate configuration cycles represents one the best nonrenewable resources because its high heating value and low environmental effects. can be converted to liquefied (LNG), via liquefaction process, which is used as a heat source sink in various multigeneration cycles. In this paper, new cycle proposed LNG sink. This includes CO2 cyc...

Abstract A sequential one‐pot chemoenzymatic procedure for the conversion of diol 1 , easily obtained from oleic acid, into pelargonic and azelaic acids is herein described. The oxidation a mixture corresponding regioisomeric hydroxyketones was promoted by an alcohol dehydrogenase Micrococcus luteus selected after extensive screening commercial enzyme kits strain collections. stereochemistry pr...
