| Abstract: | Color reactions of thorium with six unsymmetric arsenazo reagents are discussed. The acid stability of diverse complexes formed was studied and the toleiance to the major interfering ions compared. It was found that DBN-arsenazo excels all other reagents in selectivity and sensitivity for the determination of thorium. |
