Application of green iron nanoparticles supported on biochar for the removal of selected organochlorine pesticides from water / Samavia Batool

In this work, novel green iron nanoparticles supported on biochar (INPs-Bg) were prepared for the efficient removal of organochlorine pesticides (OCPs) from water system. For this purpose, four biochars were prepared from four biomass wastes of Rambutan fruit peel (BRtP), Oil palm leaf (BOpL), Jackf...
