Simultaneous Determination of Ionic Nutrients in Liquid Fertilizer for Hydroponic Culture Using Ion Chromatography with Alkaline Eluent Open
本研究では,塩基性溶離液(NaOH)と強塩基性陰イオン交換樹脂分離カラムを組み合わせた液体肥料中のイオン性栄養塩類(K+,NH4+,NO3−,NO2−,HPO42−)の同時分離定量法を応用し,水耕栽培における液体肥料中のイオン性栄養塩類の濃度変動に関するモニタリングと施肥管理を試みた.その結果,本法の適用により,水耕栽培において用いる液体肥料中の主要イオン性栄養塩類であるK+,NO3−,HPO42−の変動に関するモニタリングが可能であった.また,水耕栽培における液体肥料の一…
