Title: Determination Of Calcium And Magnesium In Limestone And Dolomite By Enthalpimetric Flow-injection Analysis
Author: de Oliveira W.A.
Mendes A.S.
Abstract: A flow-enthalpimetric method for the determination of calcium and magnesium in limestone and dolomite is described. Calcium is determined by measuring the heat evolved from the substitution reaction with Mg-EDTA. The amount of magnesium is calculated from the calcium content and the enthalpimetric signal for the reaction of the sample solution with disodium-EDTA, which gives the total concentration of calcium and magnesium. Analysis of reference materials and other samples indicates an error not exceeding 0.3% of CaO and MgO, and a sampling rate of 100 samples per hour. © 1987.
