“…A number of natural sorbents have been studied for use in oil-spill cleanup, e.g. cotton (Choi and Kwon 1993;Choi, 1996;Johnson et al, 1973), wool (Radetic et al, 2003), bark (Haussard et al, 2003), kapok (Hori et al, 2000, Ghalambor 1995Rowell, 1998) and rice straw (Sun et al, 2002). These agricultural products and residues are locally inexpensive and available.…”

ABSTRACT:In the present work, an attempt was made to provide an efficient, easily deployable method of cleaning up oil spills and recovering of the oil. Carbonized pith bagasse, a relatively abundant and inexpensive material is currently being investigated as an adsorbent to remove contaminants "oil" from water. Fibers extracted from bagasse and carbonized at 300 °C were found to have a high performance for sorption and recovery of light, heavy oils and even the viscous ones. The physical properties of pith bagasse were investigated using scanning electronic microscope to show the inner and the outer surface and the cross section area of the pith bagasse and thermo gravimetric analyzer to investigate the degradation profile of the pith bagasse. The carbonized pith bagasse was packed into a polypropylene bag and its sorption behavior was studied. A comparison was made between the prepared pad and the commercial sorbents show that the pad containing carbonized pith bagasse has higher sorption capacity in comparison to the commercial sorbents. The pad exhibited high oil retention ability and a high selectivity for the oils over the water. The pad showed a possibility of reuse for eight times. The sorption capacity of the pads containing carbonized pith bagasse was found to increase with increasing the time of sorption till it reaches the maximum value at the time of sorption equal to 60 min.

“…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.…”

-A synthetic rubber powder was used to adsorb the residual oil in palm oil mill effluent (POME). POME is the wastewater produced by the palm oil industry. It is a colloidal suspension which is 95-96% water, 0.6-0.7% oil and 4-5% total solids including 2-4% suspended solids originating in the mixing of sterilizer condensate, separator sludge and hydrocyclone wastewater. POME contains 4,000 mg dm -3 of oil and grease, which is relatively high compared to the limit of only 50 mg dm -3 set by the Malaysian Department of Environment. A bench-scale study of the adsorption of residual oil in POME using synthetic rubber powder was conducted using a jar test apparatus. The adsorption process was studied by varying parameters affecting the process. The parameters were adsorbent dosage, mixing speed, mixing time and pH. The optimum values of the parameters were obtained. It was found that almost 88% removal of residual oil was obtained with an adsorbent dosage of 30 mg dm -3 and mixing speed of 150 rpm for 3 hr at a pH 7. Adsorption equilibrium was also studied, and it was found that the adsorption process on the synthetic rubber powder fit the Freundlich isotherm model.

“…Haussard et al (2003) treated the bark with microorganisms or with copper or chromium solution, and Oh and Tshabalala (2007) consolidated bark pine into pellets using citric acid as cross-linking agent before removing Cd(II), Cu(II), Zn(II) and Ni(II). Treatment with acidified formaldehyde was also applied, the rationale being the reaction of formaldehyde with the phenolic hydroxyl groups leading to polymerization by crosslinking of formaldehyde with the soluble tannins and other phenolics making up an insoluble phenol-formaldehyde copolymer.…”

Tree bark is among the widely available and low-cost sorbents for metal adsorption in aqueous environments. A state-of-the-art review is compiled carrying out a comprehensive literature search on the biosorption of heavy metals in solution onto different bark species, including a characterization of bark structure and chemistry. The results indicate that biosorption has been gaining importance for bark valorization purposes. Promising heavy metal uptake values have already been attained using different bark species. These values are comparable to those obtained with commercial activated carbons. Bark has a cost advantage over activated carbon and can be used without any pretreatment. Thus, bark offers a green alternative to remove heavy metals from industrial waters. A brief survey of the chemical composition and structure of different bark species is presented. Suggestions are made to improve screening of bark species for specific heavy metal ions sorption.
