Abstract
The sorption and determination of mercury(II) on the solid phase of a fibrous polyacrylonitrile material filled with the AV-17 anion exchanger is studied. Mercury is adsorbed in the form of the chloride complex from a solution with pH 5–7.5; it is determined on the solid phase by the reaction with dithizone either visually or by the measuring the color hue. A procedure for the test determination of mercury(II) has been developed and tested in the analysis of fresh natural waters by the added–found method. The detection limit is 0.02 mg/L. The time of analysis of 5 or 6 samples is no more than 15–20 min.
