A rapid determination of Ra-226 in water using composite ion exchanger MnO2-PAN
Original language description
A rapid method for Ra-226 determination in water samples up to 10 L using MnO2-PAN (polyacrylonitrile) composite ion absorber was proposed and verified. Samples were traced with Ba-133 to monitor radium radiochemical recoveries which were in the range of (92-100) %. MnO2-PAN absorber with grain size < 0.1 mm with bed volume (BV) 2 mL was used for Ra-226 preconcentration from water samples (pH 6.5-7.0) at flow rate < 290 BV h(-1). Radium was eluted from the absorber with 20 mL of 6.5 M HCl at flow rate of 1.5 mL min(-1). Alpha-spectrometric counting of Ba(Ra)SO4 microprecipitate was used for Ra-226 determination. The developed method was used for the Ra-226 determination in 15 samples of natural mineral, mountain spring, drinking and natural healing waters from Slovakia, Slovenia and Czech Republic.
