Abstract

A modification of Hirth's method for calcium is presented. The important cations interfering in the precipitation of calcium oxalate — aluminium, copper, manganese, iron, zink, etc. — are separated as the oxinate in a buffered acid solution. In view of determining calcium in blood of marine animals, the method of Hirth for separating calcium as the oxalate has been modified so as to avoid alkalinizing the sample solution.
Calcium first separated as the oxalate is finally isolated as the phosphate, the phosphorus contents of which is determinated photometrically.
