Magnesium can be separated from calcium by elution with 3.0 IM hydrochloric acid containing 60% ethanol from a column of AGsoW-X8 cation-exchange resin. Calcium is retained and can be eluted with 3.0 IM hydrochloric acid or 2.0 IM nitric acid. The separation factor of OL&~ = 5.6 is considerably high
An automated standard additions method with an ion-selective electrode is used to determine free fluoride in plasma, urine and sea water; the amounts of pH buffer and sequestering agent are minimal. The presence of uncomplexed metal ions was allowed for in the data treatment by using modified Nernst
