The invention relates to a method for simultaneously determining the total amount of parathion-methyl and/or parathion-ethyl, and belongs to the technical field of chemical detection. According to the method, parathion-methyl and/or parathion-ethyl in a system are/is thoroughly and completely hydrolyzed by adding a hydrolysis reagent to generate p-nitrophenol, and by measuring the content of p-nitrophenol and a calculation formula. the total content of parathion-methyl and/or parathion-ethyl in the system can be obtained. The (rapid) hydrolysis reagent has the advantages of cheap raw materials, no pollution, environmental friendliness and the like, is simple to prepare and convenient to use, and can effectively improve the hydrolysis efficiency and detection efficiency of methyl/ethyl parathion. Besides, the (rapid) hydrolysis reagent has the characteristic of no toxicity, can be prepared into a reagent suitable for cleaning agricultural products such as fruits and vegetables according to needs so as to remov
