Calcium And Magnesium

A rapid ethylenediaminetetraacetic acid titration for calcium and magnesium in serum requiring 0.1 ml of blood is described. Eriochrome black T is used as the sole indicator and the end point is observed photometrically. After determination of total calcium and magnesium, the calcium is removed as oxalate, the magnesium determined separately, and the calcium obtained by difference. The method is highly reproducible and is sensitive to ± 0.1 mg% of either calcium or magnesium.

Calcium And Magnesium

In the paper are published the results of deteremination of total, Calcium and Magnesium water hardness from four caves, one karst spring and one sinking creek in the area of Žumberačka Gora Mt. in NW Croatia. Water hardness is a measure of carbonate rocks dissolution and corrosion. Besides, it can give a hint of undergorund water courses since the stream that flows from dolomite has higher Magnesium content and one that flows from limestone has higher Calcium ions content. Geological, geomorphological and hydrological characteristics of all features from which water samples were taken are also described.
