摘要：

Here, we present a method for concentrating radiocesium in seawater using ammonium molybdophosphate-polyacrylonitrile (AMP-PAN) resin using custom-made sample-loading equipment. It was designed to reduce analytical time and labor with eight peristaltic pumps connected in parallel with eight columns, each packed with AMP-PAN. Eighty liters of seawater containing radiocesium were concentrated to 0.01 L in 6 h with the proposed method and Cs recovery was > 85%. The minimum detectable activity was 0.2 mBq L-1 at 160,000-s measurement with a high-purity germanium detector.
