Using a spectrometer with an argon plasma source coupled to a high-frequency magnetic field, we developed a direct method for determining iron in urine of patients being treated with deferoxamine. The detection limit for iron was 75 nmol/L; added iron was satisfactorily recovered; and we observed no interference from deferoxamine at its most commonly used concentrations. Values for between-run and within-run precision (CV) was less than 5%. Correlation of results with those obtained with a colorimetric method involving bathophenanthroline was good (r = 0.96).
我们使用一台配有与高频磁场耦合的氩等离子体源的光谱仪，开发了一种直接测定接受去铁胺治疗患者尿液中铁含量的方法。铁的检测限为75纳摩尔/升；添加的铁回收率良好；并且我们观察到在去铁胺最常用的浓度下没有干扰。批间和批内精密度（CV）值均小于5%。与采用邻二氮菲比色法获得的结果相关性良好（r = 0.96）。
