X-Ray fluorescence determination of mercury on the polyurethane foam sorbent chemically modified by resorcinol

Abstract

Technique of X-ray fluorescence determination of mercury in water with preconcentration on the polyurethane foam sorbent chemically modified by resorcinol is proposed. It is shown that grazing-incidence excitation of mercury X-ray fluorescence directly in a sorbent phase allows increasing the sensitivity of determination and linearity range of calibration dependence of sorption – X-ray fluorescence technique by one order of magnitude.
Key words: X-ray fluorescence analysis, chemically modified polyurethane foam sorbents, resorcinol, mercury.
