Summary: | The unregulated discharge of pollutants into water bodies had become an issue which led to pollution. The utilization of fiber derived from various forms of agrowaste as sorbent are widely used as it has a high sorption capacity and efficiency. The high content of cellulose in certain plants including the crown of pineapple (PCL) would be the best solution for sorption of oil pollutant released into the water bodies which usually caused by mismanagement of those pollutant especially waste cooking oil (WCO) which are widely used in food and beverages industry. In this study, the fiber obtained would be characterized by using Thermogravimetric Analysis (TGA) and Fourier-Transform Infrared Spectroscopy (FTIR) and its effect towards sorbent dosage and time on the adsorption capacity. In FTIR, the significant result were found in C-O stretching of chemical treated PCL which do not shows any peaks in range of 1419 cm-1 to 1422 cm-1, 1244 cm-1 and 1245 cm-1 which indicated the imperfection of hemicellulose and lignin. TGA results agreed with FTIR results where hemicellulose degraded first followed by cellulose and lignin at temperatures 206C, 396C, and 480C respectively for raw PCL. The degradation of hemicellulose, cellulose, and lignin is found at higher temperatures for chemically and thermally treated as compared with raw PCL. In agreement with results from FTIR and TGA analysis, the highest sorption efficiency in pure oil were shown by thermal PCL at 33% and chemical PCL in slick oil at 16.33%. For sorption capacity, the highest value recorded was in between 6-9 g/g for pure oil and 2.5-3.5 g/g for slick oil at duration of 10 minutes. This shown that PCL have a potential to be a sorbent for WCO especially the one which undergo modification as it shows a higher capacity then the raw samples. |
