Determination of Potassium in Infusion Solutions Using Cation Exchange Separation and Radioluminography

本研究では天然放射性核種である40K由来のβ−線計測を利用した輸液中カリウム濃度の定量法を検討した。輸液試料40 mL中のカリウムイオンを陽イオン交換樹脂3 gへ吸着させ,グルコース等の共存成分を除去した。ラジオルミノグラフィにて種々の輸液中カリウム濃度を計測し,40及び60 mEq/Lの各種輸液において真度95–105%の範囲で定量可能であることを見出した。本法はカリウム輸液による医療事故防止への応用が期待される。
