| Abstract: | Summary Embelin is reported as a new reagent for gravimetric estimation of (1) uranium in pure solutions at pH 6.0–6.5 and (2) thorium in acid solutions of 0.4 N HCl. In both cases, the precipitates were ignited and weighed as U3O8 and ThO2. The separation of thorium from large excess of uranium and rare earths could also be effected employing this reagent. In addition, Cu, Cd, Ca, Ba, Sr, Al, Be, Mn, Mg and Zn do not interfere. |
