; ;
A colorimetric method of thorium determination by sulfophenazoxine, arsenazo, and thoron was developed. The colorimetric determination of Th by thoron was achieved in the presence of U/sup 6+/, Ce/sup 3+/, and La. It is also shown that thorium determination by arsenazo is possible in the presence of uranium and rare earths. The thorium composition with arsenazo was found to be in a ratio of 1:1. (R.V.J.)
