The invention discloses a preparation method of efficient and recyclable pH test paper, and particularly relates to test paper capable of changing color in real time according to the pH of an oil product. The preparation method of the pH test paper comprises the following steps: mixing a zwitterionic compound synthesized by reaction of alkenyl pyridine and sultone with an initiator, a cross-linking agent and an amphiphilic monomer to prepare a precursor solution, uniformly soaking the precursor and a matrix, and drying in a heating or ultraviolet radiation mode to prepare the pH test paper. The test paper has the advantages of being recyclable and high in detection efficiency, and can be applied to the field of detection of white oil and derivatives thereof.
