Determination of sodium, potassium, calcium, magnesium, copper, iron, cobalt nickel, manganese, zinc, cadmium in lithium carbonate by plasma atomic fluorescence spectrometry

For the determination of impurity elements in lithium carbonate, most of the literature uses emission spectrometry to perform simultaneous determination of multiple elements. Or flame spectrophotometry to determine alkali metal elements, the remaining elements need to be separated and enriched, and then absorbed by atoms Or spectrophotometric method for single element determination "I. Due to the emission spectrum method, it is difficult to overcome the line interference, and the single element determination procedure is cumbersome, which brings certain difficulties to the analysis.
