“…Ahmad et al, (2004) applied chitosan, a biopolymer, to adsorb residual oil from POME. Fibrous sorbents prepared from natural plants, such as milkweed floss, kenaf, kapok, straw, corn cob or ear, wood fibers, sawdust, bark and cotton, have been reported as potential adsorbents (Shukla et al, 2002;Setti et al, 1999;Haussard et al, 2003;Inagaki et al, 2002). Satisfactory results were obtained using these natural adsorbents.…”
