Method for rapidly measuring content of calcium in impurity removal liquid of intermediate product in chemical rhenium precipitation process

The invention discloses a method for rapidly determining the content of calcium in an intermediate product impurity removal solution in a chemical rhenium precipitation process, which comprises the following steps: preparing a calcium standard solution; preparing the calcium standard solutions into calcium standard series solutions with different calcium concentrations, putting the calcium standard series solutions into an inductively coupled plasma emission spectrometer to measure light intensity values, and drawing a calcium standard curve; taking the filtered impurity removal liquid, adding hydrochloric acid, and adding water to prepare a solution to be detected; and putting the solution to be measured into an inductively coupled plasma emission spectrometer to measure a light intensity value, and obtaining the calcium content in the impurity-removed solution according to the calcium standard curve. The determination method provided by the invention is simple in sample treatment, wide in linear range, mult
