摘　　要：选用HCl（2％）处理螯合铁样品,建立了电感耦合等离子体原子发射光谱法（ICP-AES）快速测定螯合铁含量的方法,实验确定了最佳测定条件,采用标准曲线法为定量依据,得出样品的相对标准偏差（RSD）为0.42％（n=6）,加标回收率为98.48％～99.43％.建立的方法处理样品简单、快速,测定结果准确可靠,令人满意.A method for the determination of chelated iron in chelated fertilizer was established by the inductively coupled plasma atomic emission spectrometry （ICP-AES）. The samples were pretreated with 2% HC1. The optimized experimental conditions were obtained using the standard curve method as the basis of quantitative analysis. The results showed that the relative standard deviations （RSDs） were 0.42% （n= 6） with 98.48% ~99.43% recoveries. The proposed method has simple operation, fast analytical speed and accurate results for fertilizer analysis with satisfactory results.
