Abstract: A method for treating a waste plastic based on a persulfate system is provided. The method includes the following steps: mixing the waste plastic, sulfuric acid, sulfate, peroxymonosulfate, and water, and reacting at 80-140° C. for 3-15 h to complete the treatment; where the waste plastic is polyethylene or polyethylene terephthalate; and the sulfate is copper sulfate or ferrous sulfate. The present invention reasonably regulates and controls each parameter in the reaction process while constructing a homogeneous catalysis system of transition metal activated peroxymonosulfate, and finally directionally converts the waste plastic into C7H12 and C10H12 fuels, which realizes high-efficiency recycling of the waste plastic, has a simple and convenient working procedure, and has a wide application prospect.
