The invention relates to a method for measuring molten salt chloride residues and recycling chemical components in regenerated substances, and belongs to the technical field of detection analysis of element component content. The method comprises the following steps: weighing a to-be-measured sample, dissolving the to-be-measured sample with a dilute nitric acid solution, adding water to dilute in a special solid-liquid dilution ratio to form a to-be-measured solution; and then, measuring the content of chemical elements such as potassium, iron, magnesium, manganese, calcium, chromium, nickel, vanadium, titanium, copper and lead in the to-be-measured solution through an inductive coupling plasma atomic emission spectroscopy. The method disclosed by the invention can be used for simultaneously obtaining the contents of molten salt chloride residues and the chemical element components in the recycled generated substance sample by one step, simple, quick, few in operation step, few in disturbing influence factor, high in measuring efficiency for the substrate components and trace impurities, short in inspection period and low in analysis cost.
