Spectrophotometric Determination of Trace Amounts of Calcium Using the Calcium Complex with Alizarin
The reaction between calcium and alizarin (ALZ) was investigated for the spectrophotometric determination of trace amounts of calcium. The cationic surfactant, cetyltrimethylammonium bromide (CTAB) was useful to increase the sensitivity. The beta-correction method was applied for the determination o...
