Direct X-ray fluorescence
determination of mercury on polyurethane foam sorbentS
Abstract
Advanced technique of sorption –
X-ray fluorescence determination of mercury (II) in water with static and
dynamic preconcentration in the form of iodide complexes on polyurethane foam
sorbents on the basis of ethers were proposed. It was show that optimization of
conditions of analytical signal formation allows to increase sensitivity of
X-ray fluorescence determination and linearity range of calibration curves
essentially (up to one order and more).
