Method for determining chloride ions in nitro-type molten salt

The invention relates to the field of chloride ion quantitative detection methods, and particularly discloses a method for determining chloride ions in nitro-type molten salt. The method for determining the chloride ions in the nitro-type molten salt comprises the following steps: detecting the peak area of a chlorine standard solution on the basis of an ion chromatograph, and drawing to obtain a chloride ion mass fraction-peak area standard curve; drying the nitro-type molten salt sample to constant weight, and cooling to room temperature; the method comprises the following steps: dissolving 1-3g of a nitro-type molten salt sample in 20-40ml of water for determination, uniformly mixing, and adding the water for determination to a constant volume of 100ml to obtain a to-be-tested solution; the peak area of the to-be-tested liquid is detected through the ion chromatograph, and the detection result of the mass fraction of the chloride ions in the to-be-tested liquid is obtained based on the standard curve; the
