Popis:	Optimal conditions have been found for the modification of compact liquid phases based on a cationic surfactant, cetylpyridinium chloride, with salicylic acid. On the example of the system tin-phenylfluorone we have shown the applicability of such phases to the preconcentration of multiply charged ions readily hydrolyzed metals. The influence of concentrations on the absorbance and composition of the complex has been studied; the optimal conditions of its extraction have been found. The developed spectrophotometric procedure of tin determination with phenylfluorone using micellar-extraction preconcentration has been tested for the analysis of canned vegetables and brines.
