The invention discloses a method for detecting a zinc element of a cold-plated zinc coating through X-ray fluorescence. Comprising the following steps: 1, selecting a sample; step 2, processing a sample wafer; step 3, setting detection conditions of the X-ray fluorescence spectrometer; and step 4, detecting each sample of the selected galvanized plate by using an X-ray fluorescence spectrometer to obtain the fluorescence intensity of the zinc element, if the fluorescence intensity meets the uniformity requirement, taking the galvanized plate as an internal control standard plated plate, and detecting the thickness of a galvanized layer of the selected internal control standard plated plate by using a metallographic method, the detection result is used as the zinc coating thickness value of the internal control standard plating plate; 5, drawing an X-ray fluorescence correction curve; and 6, calculating the thickness of the zinc coating according to the measured fluorescence intensity of the zinc element in th
