Application of Paper Partition Chromatography for Estimation of Calcium and Magnesium Especially in Water

Abstract

I studied the estimation of calcium and magnesium especially in water, by the method of paper partition chromatography. In this method, the max. relative error is 5 %.
Main points of this method are;
(1) the separation of Ca and Mg by the method of paper partition chromatography, and
(2) colorimetric estimation of alizarin solution extracted from Ca or Mg alizarin lake on the strip of filter paper.
