Manuscript received 28 June 1976, accepted 10 November 1976 Phenylhydrazine sulphinic acid, a new analytical reagent has been employed for the gravi-metric determination of tellurium in presence of several metals. The reagent precipitates tellurium quantitatively from strong hydrochloric acid solutions ranging from 25 to 75% by volume, 5 to 100 mg of the element can be estimated rapidly by this procedure,
