Increase of impervious surfaces in urban area followed with increases in runoff volume and peak flow, leads to increase in urban storm water pollution. The polluted runoff has many adverse impacts on human life and environment. For that reason, the aim of this study was to investigate the efficiency of nano iron oxide coated sand with and without magnetic field in treatment of urban runoff. In ...

BACKGROUND Discharge of heavy metals such as hexavalent chromium (Cr (VI)) and nickel (Ni (II)) into aquatic ecosystems is a matter of concern in wastewater treatment due to their harmful effects on humans. In this paper, removal of Cr (VI) and Ni (II) ions from aqueous solution was investigated using an amino-functionalized magnetic Nano-adsorbent (Fe3O4-NH2). METHODS An amino-functionalized...

today, water resources stored in reservoirs is one of the basic sources of drinking-water. the elements in the sediments of reservoirs are the most important factors affecting water quality. unlike the primary plan, due to water shortage problems, nowadays, almost all the stored water in the kardeh reservoir is allocated to drinking water. from the other side in the catchment area of this dam a...

Immiscible metals due to their inherent specs are insoluble over the steady state. Developing an innovative approach to this issue would be fascinating and challenge the overriding rules. Herein, we proffer the principles of synthesis of Cu-Nb nanocomposites using electrochemical deoxidation route. This method consists of the cathodic electrolysis of the nanoparticles Cu-Nb2O5 through the...

unsubstituted phthalocyanines of co, fe and mn supported on zinc oxide nanoparticles were prepared and were well characterized with x-ray diffraction (xrd) and scanning electron microscopy (sem). the oxidation of alcohols with tert-butylhydroperoxide (tbhp), in the presence of metallophthalocyanines (mpc) supported on zinc oxide nanoparticles was investigated. these mpc/zno nanocomposites were ...

Nickel is one of the toxin heavy metals in surface waters. Developing new approaches aimed at removing heavy metals from aqueous solutions that are simultaneously economical and environmentally friendly is of great importance. The purpose of this study will be using Nano-lignocellulose adsorbent as a natural material to remove nickel heavy metal. In this study, several important environmental p...

composites with micro- and nano-metal fillers has attracted the attention of researchers for radiation shielding applications. Lead toxicity and heaviness have oriented extensive research toward the use of non-lead composite shields. The present study aimed to systematically review the efficiency of the composite shields of various micro- and nano-sized materials as composite shields have been ...

Nanoparticles with high reactivity can be applied as amendments to remediate soil metal contaminations by immobilizing toxic elements. Nano-oxides of Fe have been studied but Al and Ti nano-oxides not tested for their remediation capacity metals. The potential synthesized iron (Fe-O), aluminum (Al-O), titanium (Ti-O) stabilizing Cd, Pb, Zn in mine spoil (Chat) contaminated was compared using ad...
