| description | The invention provides a method for detecting trace elements in a zinc layer of a galvanized sheet. The method comprises the following steps: firstly, sealing one surface and the edge of a to-be-detected sample which is cut into a proper size, reserving the other surface as a detected surface, cleaning the detected surface by using a cleaning agent, blow-drying for later use, and weighing the mass of the detected surface as m1; placing a to-be-detected sample in a container, adding an acid solution for treatment, then taking out the sample, flushing the surface of the sample with distilled water, merging the flushing liquid into the solution, and fixing the volume to obtain a to-be-detected solution; the surface of the sample subjected to acid treatment is cleaned with a cleaning agent, blow-drying is conducted, and the mass of the sample is weighed to be m2; preparing a standard curve solution of to-be-detected elements to obtain a standard curve of the to-be-detected elements; and detecting the to-be-detect |
