Oxidizing radical formation was tested in paper mill water together with biocides. The investigation of electrochemical behavior of biocides on SS 2343 and MMO (mixed metal oxide) electrode surfaces was conducted in synthetic paper mill water (cPMW). Hydrogen peroxide and peracetic acid gave response to the polarization on the anodic and cathodic sides on the SS 2343 electrode surface. At the MMO electrode the phenom Read More

Electro-Fenton process has gained considerable interest for its application in water treatment for the removal of recalcitrant organic pollutants. This review is based on an overview of the electro-Fenton process applied for water treatment. The process mechanisms and fundamentals of the operation are explained. The applications of the process in water treatment have been reviewed. The major advantages of the process Read More

This study reports on comparative performance of electro-Fenton and photo-Fenton processes in the mineralization of three cationic dyes: BB41, BR46 and BY28. Primary objective was to determine the optimal conditions for both processes. It has been shown that the mineralization rate by electro-Fenton process depends on operating parameters such as applied current density, catalyst concentration, pH, etc. It was also ob Read More

Aqueous solutions of Rhodamine 6G (R6G), one of the more used xanthene dye, were treated by hydroxyl radicals (.OH) electrocatalytically generated through the electro-Fenton process, a powerful and environmentally friendly electrochemical method. Platinum (Pt) or boron-doped diamond (BDD) anodes were used with a carbon-felt cathode. The effect of anode nature and applied current on the degradation and m Read More

The present work studied, for the first time, the removal of organic pollutants from a reverse osmosis (RO) concentrate by a three-dimensional electrode reactor using γ-Al2O3 /Sn-Sb oxide as particle electrodes. The morphological characterization and composition of the particle electrodes was studied by SEM, XRD and XPS, and the effects of current density and initial pH on the COD removal were investigated. The three-di Read More

The low-valent titanium (LVT) reagents have gained widespread acceptance in organic synthesis since their first use in 1973. McMurry coupling reaction uses the LVT (low-valent titanium) reagents. This article is an attempt to review the broad synthetic utilizations of this reagent in inter and intramolecular coupling of carbonyl groups in olefination, resulting in the formation of heterocyclic compounds.

Polycyclic aromatic hydrocarbons (PAHs) are of great interest due to their excellent optoelectronic properties and selfassembling properties. As a class of PAHs, star-shaped PAHs have a particular two-dimensional architecture and can self-assemble into three dimensional packed structures. Therefore, star-shaped PAHs have displayed comprehensive application in organic semiconducting materials. In this review, we will focu Read More
