Ratio Determination of Antimony Trisulfide and Potassium Chlorate by Atomic Absorption Spectrophotometry
An atomic absorption spectrophotometric method for the determination of the ratio of antimony trisulfide to potassium chlorate in 0.2–0,4 mg igniter beads has been developed. The sample is dissolved in acids. diluted with distilled water, and aspirated directly into the acetylene-air flame of the atomic absorption spectrophotometer. Measurements of antimony and potassium concentrations are made from the same solution. The results agree with those obtained by the colorimetric iodoantimonous acid method. The analysis requires one third the time of the conventional colorimetric method.
