The reliability of a colorimetric determination of magnesium (Mg) and calcium (Ca), and a tubidimetric determination of potassium (K) were evaluated. The concentrarions of Mg, K and Ca were determind with xyldil blue (XB), tetraphenylboron (TPB) and orthocresolphthaleincomplexone (OCPC) method, respectively. The detective range of each element was followed ; Mg > 1.25mg/dl, K > 6.25mg/dl, and Ca > 2.5mg/dl. These colorimetric determination of XB and OCPC methods were specific for Mg and Ca, and no interference with other elements was observed. The determination of K was slightly interferred with other elements. XB and OCPC methods were applied both dry-aching and HCl etxraction samples, however, K content measured by TPB method using HCl extraction samples had tendency to underestimate than those using ashing samples. Therefore, the determination of K in HCl extraction samples needs to assay the K concentration of sample as control simultanously.
