Abstract: Application of oscillopolarographic titration to EGTAtitration of Ca in presence of Mg gives satisfactory results, with Ca:Mg = 1:40.Small amounts of Fe、Al、Ti、 Mn and Pb, which are precipitated in the titration cell without filtration give no interference.The end point is sharp.Being rapid and accurate, the method can be used in limestone analysis.
