Analytical - Method: | Method according to Schwarzenbach with o-cresolphthalein complexone.3 Calcium ions react with o-cresolphthalein complexone (o-CPC) under alkaline conditions to form a violet colored complex. The addition of 8-hydroxyquinoline prevents interference by magnesium and iron. Alkaline pH Ca2+ + o-CPC calcium-o-CPC complex The color intensity of the complex formed is directly proportional to the calcium concentration and is measured photometrically. |
