Background: 4-Chlorophenol is used frequently in industries including refineries petrochemical, industries pesticide industries and many others. This compound causes damage to environment. The purpose of this research was the survey of 4-chlorophenole degradation by Fe°/H2O2 of synthetic wastewater and resulting intermediate compounds.   Methods: This study is an applied- experimental researc...

Abstract Background and Objective: Perchloroethylene (PCE) is a chlorinated hydrocarbon used as a solvent in many industrial processes. In contaminated water and soil a great deal of PCE is found. This study aimed to determine the rate of decomposition of PCE occurred after advanced oxidation. Material and Methods: In this descriptive-analytic study conducted (2011) in public health faculty...

Background: The reaction of natural organic matters (NOMs) with chlorine in the conventional disinfection process results in disinfection by-products (DBP) such as trihalomethanes and haloacetic acids. Due to the potential health risks of trihalomethanes for public health, it has attracted a lot of attention. The purpose of this study is to investigate the performance of combined Fenton-ultraso...

This study the effect of seed preparation (priming) with different concentrations of hydrogen peroxide on the anatomy of the flag leaf and spike two wheat genotypes( Cross Sabalan ( bread wheat) and Saji(durum wheat)) and its relationship with grain yield, under dry land farming system condition, Experimental design was factorial, arranged in randomized complete block. Results showed that the n...

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Background and Objective: Antibiotics are hardly decomposable and resistant contaminants in the environment that according to their anti-biological properties, it is necessary to eliminate or reduce the amount of them before entering the environment. Therefore, the main goal of this research is to investigate the Fenton and Fenton-like process efficiency for the treatment of wastewater containi...

Background: Due to the large volume of water consumed in textile industry and producing the colored wastewater containing non-biodegradable organic dyes, in the present study the interaction of hydrogen peroxide and nanophotocatalyst in the advanced oxidation process was investigated. Methods: In this research, after synthesizing of nanophotocatalyst (ZnO:Ag:Nd) the effect of hydrogen peroxide ...
