Determination of manganese in cements and their raw materials by atomic absorption spectrophotometry

Atomic absorption spectrophotometric analysis of ceramics and their raw materials. V

Abstract

Atomic absorption spectrophotometric methods have been established for the determination of manganese in cements and their raw materials. The determination is interfered with mineral acids, but the constituents usually found in the samples did not give any disturbance. The calibration curve for manganese was found to be slightly deviated from a linear line. Manganese in the samples were determined rapidly with satisfactory accuracy and reproducibility.
