A Semi-Automated Technique for the Separation and Determination of Barium and Strontium in Surface Waters by Ion Exchange Chromatography and Atomic Emission Spectrometry

Abstract

A semi-automated method for the separation and the analysis of barium and strontium in surface waters by atomic emission spectrometry is described. The method employs a semi-automated separation technique using ion exchange and an automated aspiration-analysis procedure. Forty specimens can be prepared in approximately 90 minutes and can be analyzed for barium and strontium content in 20 minutes. The detection limits and sensitivities provided by the described technique are 0. 00 3 mg/l and 0.01 mg/l respectively for barium and 0.00045 mg/l and 0.003 mg/l respectively for strontium.
