Abstract:Box-Behnken design (BBD) was employed to study an optimal treatment method of synthetic lignin wastewater effluent from pulp and paper wastewater treatment plants using iron (III) trimesate (Fe-BTC) as an alternative coagulant aid. Fe-BTC was prepared by hydrothermal technique using ferric chloride hexahydrate (FeCl3·6H2O) combined with 1,3,5-benzenetricarboxylic acid (trimesic acid, H3BTC) in deionized water and ethanol. X-ray diffractometry and Fourier transform infrared spectroscopy were used to characteriz… Show more
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.
