建立了流动注射化学发光法测定伊班膦酸钠。伊班膦酸钠被破坏转化为无机磷,与钼酸铵在酸性条件下形成磷钼杂多酸,与鲁米诺在碱性条件下反应产生化学发光。伊班膦酸钠溶液在5～25μg/ml浓度范围内线性关系良好。回收率大于97.6%,RSD小于2.0%。
Flow injection chemiluminescence was established for the determination of ibandronate. Ibandronate sodium is destroyed into inorganic phosphorus, and ammonium molybdate in acidic conditions to form phosphomolybdic heteropoly acid, and luminol reaction under alkaline conditions to produce chemiluminescence. Ibandronate sodium solution in the 5 ~ 25μg / ml concentration range of good linear relationship. Recoveries were greater than 97.6% with RSDs less than 2.0%.
