【 摘 要 】

UCO is one of the domestic wastes in our daily life. Normally, UCO are produced by hawkers, restaurants and household in a large quantity. The UCO usually exist in water mixture and eventually can cause water drainage problem which can lead to the environmental problem. Therefore, in order to overcome this problem, a study was conducted to test the adsorption of RKF and MKF towards the UCO. As for the MKF, the adsorption was tested by using different concentrations of Calcium Oxide (CaO) in percentage during the esterification. The oil removal percentages were calculated for RKF and MKF. Based on the results, it was found that the RKF has adsorbed 25.32g of UCO with a 50.64% of adsorption. As compared to MKF, it was able to increase the hydrophobic properties which resulted more UCO adsorption by 26.78g of UCO with the increment in the adsorption of 53.56% by using CaO of 5 wt% of RKF mass. However, when the percentage of CaO was increased, the UCO adsorption was also increased. The results showed that by using CaO of 10 wt% and 15 wt% of RKF mass, the UCO adsorption was increased to 28.50g (56.84%) and 31.73g (63.46%), respectively. Thus, MKF has higher adsorption of UCO compared to RKF. The highest amount of UCO adsorption has been achieved by using CaO of 15 wt% in the esterification, which was 31.73g corresponded to 63.46%.
