Synthesis and characterization of poly (styrene-co-acrylamide)-graft-polyanilines as new sorbents for mercuric present in aqueous hydrocarbon liquids

Abstract Background The unprocessing hydrocarbon oil often contains high concentrations of mercury, which damages the metallic processing components and have health risk on workers environment. Mercuric removal unit associated with natural gas plant is failed to complete mercury then distributed in most places unit. Most unremoved are found polar solutions. Results Styrene-co-acrylamide-graft-polyanilines were synthesized characterized. copolymer formed by free radical emulsion copolymerization styrene-acrylamide (14:1) using ammonium persulphate (APS) at 60 °C. In addition, grafting process was also achieved oxidation chemical polymerization above both aniline 2-chloroaniline APS. synthetic polymeric samples characterized infrared (IR), x-ray diffraction (XRD), scan electron microscope (SEM), transition (TEM), thermogravimetric analysis (TGA) Brunauer–Emmett–Teller (BET) confirm investigate as new sorbents for Hg (II). Both adsorption kinetics isotherm models checked. Conclusions cases (II) adsorbed multi-layer obtained mesopores materials. enhances activity towards removal. from water solution portion mercuric introduction material based styrene-co-acrylamide-graft-polyanilines. efficiency closed 100% case poly (2-chloroaniline).
