摘要：NOVELTY - Removing water in chloro-olefin through in situ chemical oxidation comprises (i) adding water in a reaction bottle, then adding sodium hexametaphosphate and surfactant, then adding chlorinated olefin with fixed mol ratio of potassium permanganate solution, (ii) adding chloro-olefin solution in the reaction bottle, then filling water in the reaction bottle, and (iii) placing the step (ii) reaction bottle in the organic glass cylinder, reacting in a constant temperature culture box, and obtaining the treated water. USE - The method is useful for removing water in chloro-olefin through in situ chemical oxidation (claimed). ADVANTAGE - The method is simple and easy to operate, is economical, and uses trichloroethylene and tetrachloroethylene which increases dechlorinating efficiency by more than 19.5% and 7.5%, respectively.
