Analysis of calcium, magnesium in brine - Metrohm

In this Process Application Note, the analysis of low concentrations of calcium and magnesium (0–20 µg/L) in brine is addressed. The presence of calcium and magnesium can shorten the performance and lifetime of the membranes used in the chlor-alkali industry for the production of chlorine. Accurate online monitoring of the hardness is needed in several stages of the process.

analysis methods. We carried out an isotopic dilution assay to quantify the plant ‑available pools of calcium, magnesium and potassium and trace the soil phases that support these pools in 143 individual soil samples covering 3 climatic zones and 5 dierent soil types. For 81%, 87% and 90%

Calcium and Magnesium Determinations by EDTA Titrations ...

The other three methods consisted of direct titrations (d) of mangesium with EDTA to the EBT endpoint after calcium had been removed. If desired, calcium could then be estimated by subtracting the magnesium titration (d) from the titration for calcium plus magnesium (a). For removal of calcium, three precipitation procedures were compared.

Background and aim: Recent clinical studies have demonstrated that plant sterols moderately lower serum cholesterol levels in patients with mild hypercholesterolemia. Furthermore, there is evidence suggesting that mineral nutrients, such as calcium and magnesium, may also decrease serum cholesterol concentrations.
