COMPOSITION FOR REMOVING HEAVY METAL CD FROM WATER, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF

摘要

Disclosed in the present application are a composition for removing heavy metal Cd from water, a preparation method therefor, and an application thereof. The method comprises: metering a water-based fatty acid ethyl ester suspoemulsion and a silicon-rich solution in a volume ratio of 1:100 to 100:1; putting the metered water-based fatty acid ethyl ester suspoemulsion and silicon-rich solution into a reaction kettle having a stirrer; performing stirring 50-100 r/min for 30 min-14 days at normal temperature to obtain the composition for removing the heavy metal Cd from water. Provided is the preparation method for the composition for efficiently, environmentally friendly, and safely removing the heavy metal Cd from water to purify cadmium-polluted water. The final product can be used for purifying natural and industrial polluted water. The final product can be separated from a water surface for combustion or serving as a diesel engine fuel. Ash generated by the process contains high-content cadmium, and therefore can be used as a raw material for producing heavy metal cadmium; the method implements cycle industry, and is an environment-friendly method.
