ABS>Spectrophotometric studies on the composition and stability of the chelate formed between thorium and 1-(oarsonophenylazo) -2-naphthol 3,6- disulphonate (thoron) was made at pH 3.0. The chelate is red in color with lambda /sub max/ at 515 m mu . The composition, as determined by different methods, is 1: 2 (metal: chelating agent). The chelate is stable between pH 1.O and 6.5. The values of log K, as determined by two different methods, are 9.4 plus or minus 0.3 and 9.8 plus or minus 0.2, respectively at pH 3.6 and at 25 deg . (auth)
