In the photometric determination of thoriu.n with thoronol, it is found that dehydroascorbic acid may be used as an effective masking reagent for zirconium. The optimum conditions has been investigated and a procedure is given for the determination of thorium in the presencx of zirrnmum. The method has been used for the determination of thorium in monazite sand and satisfactory results were obtained.
