Removal of Oil Spills Using Mango peels as Natural Adsorbent

Abstract

Oil spills is one of the major type of pollution that is disturbing the ecosystem. Majorly oil spills occurs in the ocean due to the negligence of the human activities because generally the crude oil is transported with the help of ships where water is the main means of transportation which results in the damage of the aquatic life. In this study sorbents are used to remove the oil spills that occurred on the surface of the ocean water. Naturally available sorbent is used in this removal process namely Mango peels powder. As it is difficult to collect the oil spills sample from surface of the ocean here in this study we prepared synthetic oil solution by mixing the 5liters of crude oil into 25liters of distilled water. After the synthetic oil sample is prepared we vary the sorbent heights as 5cm, 10cm, 15cm, 20cm, 25cm, 30cm and plot the graph between the %removal efficiency and the bed height by maintain the constant contact
time as 20min and flow rate as 0.3mg/lit and as the column studies are going on the studies that are done in this project is Bed Depth Service Time (BDST) where the graph is plot between bed height and service time i.e. the 350ml of sample is collected and the time is measured for that 350ml which is the maximum sorption capacity of the adsorbent for different heights of different adsorbent dosage height i.e. bed depths. The efficiency for the removal of oil spills observed by using Mango peels is 94.22% and percentage removal of the oil varies from 80.92% - 94.22% at constant contact time of 20 min and flow rate of 21.6 mL/min for varying bed heights i.e. from 5cm to 30cm respectively.
