The invention belongs to the technical field of PDS content detection, and particularly relates to a rapid PDS content detection method in an HPF method, and the method comprises the following steps: S1, adopting a three-electrode system prepared from a commercial screen-printed electrode as an electrochemical detection device, and modifying commercial screen-printed electrode loaded MOFs; s2, an electrode of the electrochemical detection device is externally connected with an electrochemical workstation; s3, a portable PDS comprehensive detector is used for conducting DPV electrochemical detection, due to the fact that MOFs have high stability in some harsh chemical environments, the application of the MOFs can cover a wide range, the MOFs serve as a modification material of a screen-printed electrode, the MOFs make direct contact with the substrate environment, direct contact between the screen-printed electrode and the substrate environment is avoided, and the DPV electrochemical detection efficiency is im
