Na. D'Yachenko et al., Sorption of silver on silica gel modified with N-propyl-N '[1-(2-thiobenzothiazole)-2,2 ',2 ''-trichloroethyl]urea groups and its use in analysis, J ANALYT CH, 55(9), 2000, pp. 851-853
Conditions for the separation of silver from predominant amounts of transit
ion and platinum-group metals on a sorbent containing N-propyl-N'[1-(2-thio
benzothiazole)-2,2',2 "-trichloroethyl]urea groups were found. A procedure
was developed for the sorption-atomic-absorption determination of silver.
