- 中文摘要: With a flow injection technique, the content of sulfate in solution was determined indirectly from the concentration of partially equilibrated barium ion in solution. To obtain improved sensitivity, atomic absorption spectrophotometry of a flame was used to determine barium. With these procedures combined with a linear calibration graph, superior sensitivity and detection limit of sulfate determination were obtained compared with those from other indirect methods.
