Degradation of chlorophenol by in-situ electrochemically generated oxidant     

丛燕青  吴祖成  叶倩  谭天恩 《Journal of Zhejiang University. Science. B》2004,(2)

INTRODUCTION With the development of industry, more and more pollutants are discharged into environment, among them, phenolic wastes are typical contami-nants considered to be hazardous and top priority toxic pollutants listed by the USEPA. They are toxic even at low concentration. Due to their biorefractory, bioaccumulation and carcinogenic potential, the treatment of these contaminants is very important in environmental protection. Various technologies and processes have been tried …  相似文献   

Degradation kinetics and mechanisms of phenol in photo-Fenton process     

何锋  雷乐成 《浙江大学学报(A卷英文版)》2004,5(2):198-205

Phenol degradation in photochemically enhanced Fenton process was investigated in this work. UV-VIS spectra of phenol degradation showed the difference between photo-Fenton process and UV/H2O2, which is a typical hydroxyl radical process. A possible pathway diagram for phenol degradation in photo-Fenton process was proposed, and a mathematical model for chemical oxygen demand (COD) removal was developed. Operating parameters such as dosage of H2O2 and ferrous ions, pH, suitable carrier gas were found to impact the removal of COD significantly. The results and analysis of kinetic parameters calculated from the kinetic model showed that complex degradation of phenol was the main pathway for removal of COD; while hydroxyl radicals acted weakly in the photo-Fenton degradation of phenol.  相似文献   

Dechlorination by combined electrochemical reduction and oxidation     

Cong YQ  Wu ZC  Tan TE 《Journal of Zhejiang University. Science. B》2005,6(6):563-568

INTRODUCTION Chlorinated phenols compounds used widely in industry were intentionally or inadvertently released into environment in large quantities. These chlorin-ated aromatic compounds have strong resistance to physical, chemical and biological treatments and have been listed as a priority pollutant by the U.S. Envi-ronmental Protection Agency (Lin and Tseng, 1999). Wastewater containing chlorophenols has malodor-ous odor, high toxicity, bioaccumulation and car-cinogenic potential. …  相似文献

Effect of supplementation of vitamin E, vitamin C and reduced glutathione on copper ion induced lipoprotein oxidation in renal diseased patients—Anin vitro study

The oxidative modification of lipoprotein especially low density lipoprotein (LDL) plays a key role in the initiation and progression of atherosclerosis. Serum apolipoproteinB (apoB) level is found to be an important marker for atherosclerosis. The present paper focuses on the measurement of serum apoB levels and the effect of Vitamin E, Vitamin C and reduced glutathione on the copper ion induced oxidation of LDL + VLDL (VLDL-Very Low Density Lipoprotein) lipoprotein fraction isolated from the serum of chronic renal failure (CRF) and renal transplanted patients. The level of apoB is significantly higher in the serum of transplanted patients when compared to CRF patients and normal subjects. The level of TBARS formed in oxidized LDL + VLDL lipoprotein fraction of CRF and renal transplanted patients are significantly increased than normal even in the presence of antioxidants but the level of TBARS produced, with antioxidants is comparatively lesser than that produced by oxidized lipoprotein fraction without antioxidants. It may be concluded than that produced by oxidized lipoprotein fraction without antioxidants. It may be concluded that oxidation of LDL can be prevented at an earlier stage by Vitamin E supplementation. The supplementation with Glutathione serves as the best method of preventing the lipoprotein oxidation among the renal diseased patients.  相似文献
