An improved potentiometric titration method for the determination of calcium and magnesiumin sea water has been newly devised. In this method, a mini-computer is used for the automation of titrations, and ion-selective electrodes are used as an end-point detector. Calcium is determined by titration with EGTA, and total alkaline earth metals (magnesium+calcium+strontium) by titration with EDTA. Magnesium can be determined by the difference, strontium having been determined by a suitable method. In the present method, calcium and magnesium in sea water can be determined with a precision of 0.1%.
