Indirect complexometric determination of beryllium.
An indirect complexometric method is described for the determination of beryllium, which is selectively precipitated as Be(NH(4))PO(4), then dissolved in HCl, and the solution passed through an ion-exchange column to retain Be and allow PO(4)(3-)to pass through. Phosphate is precipitated as Mg(NH(4))PO(4) and Mg in the precipitate is titrated with EDTA. Be is obtained from the Mg content.
