Popis:	The meth~od proposed by Malyshevskaya et al . [2] pe rmi t s both ana lyses to be c a r r i e d out in a single solution, does not r equ i re the p r i o r ex t rac t ion of the ion-exchange r e s in f rom the solution, and reduces the analys is t ime to 5-6 rain. L a b o r a t o r y t e s t s with this method showed, however, that it gives two to three t imes lower values for TTC and slightly higher values for CX (by 1.6-2~0 in t e r m s of CS 2) than the method used by Lapkina et al . [1 ].
