Fenton oxidation is generally inhibited in the presence of a high concentration of chloride ions. This study investigated the feasibility of using benzoquinone (BQ) and hydroxylamine hydrochloride (HA) as Fenton enhancers for the removal of glycerin from saline water under ambient temperature by accelerating the ferric system. It was found that organics removal was not obviously affected by chl...

Myeloperoxidase was purified from human polymorphonuclear leukocytes and the effect of chloride upon the EPR and potentiometric properties was studied. The redox titration between the ferrous and ferric states of the enzyme yielded n = 1 Nernst plots between pH 9 and 4, with clear isosbestic points in the optical spectra during the redox change. The midpoint potential (Em) between the ferric an...

In this issue of Blood, Ciciliano et al demonstrate that thrombus formation in ferric chloride (FeCl3) thrombosis models relies on physiochemical, rather than biological, mechanisms.

The recent trials of gentisic acid as a therapeutic agent (1, 2)’ stimulated our interest in the development of methods for the determination of gentisic acid in serum. Meyer and Ragan (1) referred to a method which is suitable for the analysis of gentisic acid in urine. No details were given. Although they were able to detect 5 y of hydroquinone per ml. in urine (l), they did not find detectab...

the efficiency of existing municipal wastewater treatment plants has been affected by the increase of incoming organic load caused by the expansions in developing countries. in the present investigation, the effect of chemically enhanced primary treatment (cept) process was studied on the enhancement efficiency of a municipal wastewater treatment plant in tehran, iran. jar test results showed a...
