| Abstract: | in this paper, a linear regression spectrophotometry of multiwavelength data ispresented for simultaneous determination of micro-amounts of calcium and magnesium with Ca(Mg)-acid chrome blue K system. The interference from some common ions can effectively be eliminated by hydroalde and sulfide precipitation separation. The method has been used for directdetermination of Ca and Mg in tap water. The rseult is satisfactory. |
