【 摘 要 】

In this study, nanofluid detergent was synthesized from methyl ester sulfonate (MES) surfactant and titanium dioxide nanoparticles while MES surfactant was synthesized from waste cooking oil (WCO), a low-cost material. The purpose of this study was to obtain an eco-friendly nanofluid detergent with optimum stability and performance. In the synthesis of MES surfactant, WCO has been purified first then followed by trans-esterification and sulfonation process. Concentrations of MES surfactant and CMC (carboxymethyl cellulose) were varied for detergent synthesis, while TiO2 concentration was kept at 0.1%. Performance test of detergent was studied by stain removal and stain degradation test. Optimum quality of MES surfactant was obtained at pH 7 with disalt content of 4.47%. The results showed at MES surfactant concentration of 1.5%, detergent had the best stability about 99% and after the addition of CMC 4%, no sedimentation occurred within two weeks. MES concentration of 1.5% has the best performance for stain removal and after the addition of CMC 4%, detergent performance increased about 14%. While stain degradation test showed that detergent performance can be improved by TiO2 photocatalytic reaction, which respectively increased about 11% and after the addition of CMC increased 5%.
