PRELIMINARY STUDY OF CHEMICALLY MODIFIED PARKIA SPECIOSA AS AN ADSORBENT FOR OIL TREATMENT

Abstract

The waste discharge containing contaminated oil to the environment rise annually due to tremendous revolution of an urbanization and industrial. The oil pollution can affect the ecology, aquatic life, environment and human health. Common practice in treating oil spill by using natural adsorbent due to it low cost and availability of the sources. This study introduced Parkia Speciosa Pod (Petai) as a new oil combating powder. The aim of this study is to produce a low-cost adsorbent in cleaning oil spill. Then, to investigate the effect of different weight dosage of adsorbent and study the influence of oil adsorption via different type of oil. The pod of Parkia Speciosa was ground and sieved before being conducted for oil treatment analysis. The powder of Parkia Speciosa was treated with soda treatment using sodium hydroxide in order to enhance the porosity of its surface. The treated adsorbent was testing to a few types of oils such petrol, diesel, used vegetable oil and lubricant oil. The results revealed that the percentage removal of oils for 1 g treated adsorbent for petrol, vegetable oil, diesel and lubricant oil were by 86%, 74.3%, 14.2% and 43.55% respectively. Based on the outcome, the Parkia Speciosa has a good potential as an adsorbent in removing oil spill.
