Abstract An AAS method for the determination of manganese in fluorspar was established for the inspection of export product. The fluorspar sample was treated with HF, then fumed with HClO4. After cooling, the residue was dissolved by adding HCl and boric acid with gentle heating. The series of standards for calibration were prepared by adding the same amount of Ca for matrix matching. The linear range of the determination of manganese is 0.09-2.5μg·mL-1. The determination limit of the method for Mn in fluorspar was 0.001 0%. Analytical results of real samples with various levels of content by the proposed method were in good agreement with those by the ISO method of spectrophotometry. The method features good precision, easy operation, and convenience for application.
