Th and certain other tetravalent elements such as U and Zr form internal complexes with the reagent arsenazo III (an organic sulfocompound containing As) which are stable in strong acids, sulfates, and phosphates. Th was determined photometrically in HCl solutions ranging from 0.01 to 10 N without finding it necessary to remove the sulfates, phosphates, or oxalates. The method was especially useful for working at concentrations from 0.05 to 1 of Th in the analysis of minerals such as alaskite granite, syenite, and nordmarkite. (TTT)
