The zero valent iron doped polypyrrole (Ppy/Fe) was synthesized via chemical oxidative polymerization method in diethylene glycol medium for the first time this study. characterization of Ppy and Ppy/Fe composites realized by using fourier transform infrared spectrometer (FTIR), UV-visible diffuse reflectance (DRS), scanning electron microscope (SEM), elemental dispersion X-ray analysis (EDX), ...

Paraoxon is an emerging organophosphate pollutant that commonly used as a pesticide and drug, hence increasing the risk of contamination water supplies. Its intensive use for vector control has led to pollutions in soil water. very toxic, with LD50 2 30 mg/kg rats. It can be metabolized body from parathion; thus, exposure lead serious health effects. In this study, zero valent iron (Fe°/ZVI NPs...

introduction     cadmium as one of the toxic heavy metal, because of harmful effects on health and the environment, has attracted a lot of attention. the main sources of cadmium emissions are the environment, the waste of electroplating, melting, alloyed manufacturing, pigments, plastics, batteries, extraction and refining processes. this metal easily accumulates in different machines of people...
