We report a new analytical method for determination of strontium in highly active liquid waste, which employs liquid electrode plasma optical emission spectrometry (LEP-OES) following online solid phase extraction (SPE). The homemade SPE column is constructed by packing Sr selective resin into a 30-cm long resin tube, which can be reused for tens of times. Preconcentration factor is estimated about 15. Total time for one measurement is 1.5 hours. The developed method is validated with the measurement of simulated HALW. We suppose that the method is able to measure 10000-fold diluted HALW with a volume of 5 mL.
