The grafting of acrylic acid onto biosorbents: Effect of plant components and initiator concentration

► The effect of plant components of radical grafting was determined. ► The optimum Fenton's reagent ratio for extracting plant components was determined. ► ORP and ΔH+ was applied in monitoring the radical initiation process. ► Relationship between initial KMnO4 concentration, ΔH+, and OPR was established. ► Relationship between percentage grafting, surface area and methylene removal was established.
