This research shows the development of a miniaturized solid-phase extraction method with UV-Vis detection for simultaneous determination dibenzofuran, fluoranthene and phenanthrene using chemometrics approaches. After synthesis Fe3O4 nanoparticles (Fe3O4 NPs), surface was modified by Triton X100 coating. The influence solvent volume, concentration X100, time, sample pH were studied optimized. D...

The present research investigates the ability of graphene oxide nanosheets for treatment of dairy wastewater, using In Situ Sludge Magnetic Impregnation” (ISSMI) to separate sludge after adsorption process. To increase the interaction between magnetic nanoparticles and graphene oxide, the former has been functionalized, using 3-Aminopropyl triethoxysilane, with the synthesized graphene oxide an...

nanoporous graphene which is used as nanosorbent was synthesized by chemical vapor deposition method via porous zinc oxide nanocatalyst. the reaction was carried out using methane as the carbon source and hydrogen as the carrier gas in a ratio of 4:1 at the temperature ranging 900-1050°c for 2-50 min. the product was characterized by scanning electron microscopy, transmission electron microscop...

The removal of crystal violet from aqueous solution by NiFe2O4 magnetic nanoparticles treated with sodium dodecyl sulfate was investigated. The modified magnetic nanoparticles were prepared by chemical reaction of a mixture of Ni+2 and Fe+3 ions mixture in aqueous solution at the presence of ammonia and then sodium dodecyl sulfate was utilized as an ionic surfactant to modified the obtained mag...

This work successfully created a polypyrrole-polyethyleneimine (PPy-PEI) nano adsorbent for the elimination of lead ion Pb2+ from an aqueous solution. An efficient conducting polymer-based called as was using ammonium persulfate (NH4)2S2O8 oxidant (PPy-PEI). The PEI hyper-branched polymer with terminal amino groups added to PPy offer heavy metals more effective chelating sites. removal solution...

The removal of sulfur compounds from petroleum is extremely necessary for industrial and environmental reasons. Sulfur in transportation fuels is a major air pollution source. In this work, the efficiency of nanostructured Ni-clinoptilolite adsorbent was investigated in the removal of sulfur from gas oil. For this purpose, the design of experiments was performed by selecting effective factors i...
