Abstract: The conditions of colour reaction of calciun and DBC-chlorophosphonazo in ethanol-aqueous medium were optimized and analytical charateristics of this colour system was examied. A decomposition method and interference-free method for determination of calcium in complex Baotou iron ores were investigated. A spectophotometry with simple separation for determination of calcium in Baotou iron ores was developed.
