Abstract

This research was conducted to modify oil palm solid wastes chemically to become oil adsorbent for palm oil mill effluent (POME). The purpose of modification on oil palm leaves (OPL) and oil palm frond (OPF) was to change the hydrophilic nature to a more hydrophobic character. This study also exploited the production of sorbent materials with high efficiency in the oil uptake for POME from OPL and OPF. Chemical modification was carried out using 200 mL of 1.0 M lauric acid solution for 6 hrs at room temperature. The modified OPL and OPF were preceded to adsorption test for POME and the capacity of oil adsorbed was compared between them. FTIR analysis supported the modification to occur with the increase in a peak of C−H group and the presence of C=O originated from lauric acid structure chain. The hydrophobicity of modified OPL and OPF samples was supported by XRD and contact angle analysis with modified OPL became more hydrophobic than the modified OPF, which had been 38.15% and 24.67% respectively. Both the analyses proved that the result from the oil adsorption test on POME showed the presence of a new peak attribute at C=C stretching of aromatics for the oil in POME proved that it was attached on the sorbent materials. Based on SEM analysis, the perforated and rough surface had been observed on modified OPL and OPF samples because oil layers on OPL and OPF surfaces were observed on the modified samples after the adsorption test. All the analyses in the study agreed that the results from oil adsorption test showed that the modified OPL had higher adsorption capacity than the modified OPF with the percentage of oil uptake at 83.74% and 39.84% respectively. The prepared adsorbent showed the potential to be used as a low-cost adsorbent in oil for POME.
