calcium in, e.g., plasma, is much greater than that of magnesium this method is undesirable. All the methods so far described involve a number of steps in their procedure; separa tion ofcalcium is often necessary. The earlier methods require as much as 2.0 ml. ofplasma. The methods have been developed chiefly
A simple, accurate, and precise ion chromatographic (IC) method for determination of total K, Na, Ca, and Mg in plant materials was developed. It involves dry ashing approximately 0.1 g of plant material, followed by dissolution of the residue in 5 m M HCl and determination of K, Na, Ca, and Mg in the digest by using a Dionex Model 10 IC.
A comparison was made of four methods for the determination of magnesium by titration with EDTA (disodiumdihydrogen-ethylenediaminetetraacetate). The first method consisted of three steps: ( a) estimation of the sum of calcium plus magnesium by EDTA titration to EBT (Eriochrome Black T) endpoint, ( b) estimation of calcium by EDTA titration to murexide endpoint, and ( c) estimation of magnesium …
