Abstract:
The objective of this study was to make surface active agent from used cooking oil and to evaluate biodegradable properties of that product. Sulfonation studies conducted on a methyl
ester derived from used cooking oil1. Methyl Ester Sulfonate (MES) prepared by reacting used
cooking oil with sodium hydroxide and methanol. This MES have superior detergent and environmental properties. Surface active properties of this product were destroyed rapidly by the
bacteria of an activated sludge2. The optimum concentration of MES to destroy the bacteria is 10
ppm. The pH of this product is about 7.8-7.9.
