Synthesis, Characterization, and Evaluation of Anion Removal Properties of Cationic Derivatives of Waste Triglycerides

Waste cooking oils (WCO) exert a detrimental effect on the environment. It is crucial for our future to either reuse or eliminate those materials. This study assesses the cationic derivatives of triglycerides derived from plant oils. Furthermore, the research also examines the potential of the synthesized materials to remove anions. The process of creating cationic derivatives involves three distinct phases. The initial procedure involves the epoxidation of the utilized cooking oil (WCO). The next procedure involves the amalgamation of epoxidized waste cooking oil (EWO) with monochloroacetic acid (MCA). The last stage involves the quaternarization reaction using tertiary amines. Triethylamine and pyridine were employed for the process of quaternarization. The derivatives were investigated using FTIR and 1H NMR spectroscopy techniques. It was determined that each altered triglyceride contains three quaternary amine groups. Insoluble adducts are generated when these chemicals are combined with multivalent anions. One gram of QT-EWO-MCA can absorb 0.059 g of carbonate, 0.0947 g of sulfate, and 0.0947 g of monohydrogen phosphate.
