Abstract: cf. C.A. 49, 8043b. The method is potentiometric and is based on the titration of Na2S by an ammoniacal soln. AgNO3 or by an aq. soln. of HgCl2 with Pt indicator electrode. The results are not affected by various amts. of OH-, CO32-, SO32-, S2O32-, and SO42-. They compare favorably with the results of the standard TAPPI method but the new method can be carried out in much less time.
