A simple procedure is created to isolate Sr from a lot of Ca, which depends on the insolubility of Ca(OH)2 in alkaline arrangement. Calcium is quantitatively isolated from Sr and over 95 of Sr is recouped from an example with as much as 50 g of Ca and a CaSr mole proportion of 250. Another method for the division of Sr from Ba and Ra is additionally researched, which is based on the distinction in dissolvability of the chlorides of Sr, Ba and Ra in HCl media. In 9.5 mol l−1 HCl or 7.5 mol l−1 HCl–10 CH3)2CO media, >97 of Ba and Ra can be evacuated by Ba(Ra)Cl2 precipitation, and >94 of Sr was recouped. In the determination of by estimating, the division of Ra and Ba can without much of a stretch be carried out by precipitation of Ba and Ra as Ba (Ra) SO4, while Y can be quantitatively recouped in the arrangement. By this method, a further division of from radio strontium can be finished. The new division method has been effectively utilized for the determination of in samples with high Ca content, for example, 45 l of seawater and 200 l of drinking water. The analytical nature of the outcomes is practically identical to that of the conventional method utilizing raging nitric corrosive and BaCrO4 precipitation.
