摘 要: 在酸性介质中,二价铁离子与邻二氮菲反应生成橙色络合物,最大吸收波长为510nm,铁离子含量在30~150mg·L^-1范围内呈良好线性关系,回收率在95%以上,可适用于水中微量铁离子的测定。 In acidic medium, Fe^2+ react with orthophenanthroline and produce orange complex whose lasgest absorption wavelength is 510nm. A good linear spectrophotometric relation was shown in the Fe^2+ conceatration range of 30 - 150mg/L and the recovery was above 95%. The method was suitable for the measurement of trace iron ion in water.
