Abstract: cf. C.A. 48, 6315h. The colorimetric detn. of Te with thiourea in the presence of other ions was studied. This method can be applied in the presence of the most of the ions with no or a little change. The colored ions in large amts. interfere. Bi is the most disturbing, next is Mo, then V and Sb. In these cases Te is pptd. with SnCl2 in a HCl medium. The detn. of traces of Te in Se is described.
