Micro and Semimicro Determination of Calcium Ion by Potentiometric Titration using Calcium Electrode and its Application in Pharmaceutical Preparation\

SummaryMICRO and semimicro determination of calcium using ion selexjtlve electrode .and its application in piimuceutical preparation.Galcium is exceedingly Lmpoz-t antr and wi.d.e Ly distri¬buted element which occur-es in nature only in combind state.Calcium ion is generally distributed in most living organisms. Aside from the role that calcium plays in the formation of skeletons~ it is present in all tissues and oella pnd is essential for maintainanco of life.Several methods have been desoribed for determination of calcium. Lon , These methods involves chemical methods (which include 2,ravilT,etric and volumetric) and in Btrwnental1 methods (including c o Loro.netird.c , spectro¬photometric, flame phot.omet rrl c and ampcriometird.o) ,In this study r.ttempts’ have boon done to establish a new method for determination of calcium ion. The results are aat Lsf ao’t or-y accurate and precise.
