Abstract. Rice husk is a by-product of the agricultural industry which could be applied for green-composite which obtained from massiveness waste-agricultural materials as a replacement to reducing expenses methods of removing heavy metal ions from wastewater. The adsorption of mercury (Hg) from solutions by a composite of polyaniline/rice husk (PAN/ RH) with hydroxypropyl cellulose (HPC) from the aqueous solutions was considered as a main purpose. The data revealed that the solution pH values of the aqueous solution indicated that Hg(II) adsorption can efficiently remove Hg(II) in pH 6 and equilibrium time of 30 min (50 ppm). The adsorption isotherms were best fitted to a Freundlich model compared to Langmuir, which indicates the adsorption of Hg (II) onto PAN/RH with R2 = 0.989. The agro-synthesized composite were analyzed and characterized by FTIR. The morphology of nanocomposite was observed by using Scanning Electron Microscope (SEM), which indicated that the polyaniline/rice husk were uniformly dispersed and highly stabilized in the presence of hydroxypropyl cellulose as a surfactant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
