DETERMINATION OF MERCURY IN WINE SAMPLES USING OF SILICA, MODIFIED BY POLYHEXAMETHYLENUGANIDINE

Abstract: the aim of the work was the development of a sorption-atomic-absorption method for determining mercury after its separation from wine samples in the form of a complex with unithiol on modified polyhexamethylene guanidine silica. The sorption-atomic absorption determination of mercury in wines was performed using the cold-steam method. The developed method is characterized by a low detection limit and a sufficiently high accuracy and satisfactory reproducibility.
