| Abstract |
A method is described for the photometric determination of thorium in soils. This involves decomposition of the sample by sintering with sodium peroxide, and precipitation on calcium oxalate. Sensitivity of the proposed method is 0.04 microg/ml. This permits determination of down to 1 x 10 to the -6th power gram of thorium per gram of soil. The analysis is performed without platinum vessels or hydrofluoric acid. |
