摘要
加乙酸钠于试样制备的溶液中,加热水解,基体元素生成碱式盐沉淀与锶钙镁分离,以 DCTA 掩蔽钙镁,锶与偶氮胂Ⅲ显色.测定结果满意.
The matrix elements were separated from strontium,calcium and magnesium by adding sodium acetate to the sam- ple solution and hydrolysis under heating.A complex of strontium was formed with arsenazo Ⅲ and the color intensity of this complex was measured spectrophotometrically.DCTA is added as masking agent to eliminate the interference from other met- als.The results obtained were good in agreement with the other methods.
