【摘要】 本文用反相流动注射分析一分光光度法研究了自来水、江水和城市废水中铁的价态,以记录双峰加和作为定量依据.Fe（Ⅱ）和 Fe（Ⅲ）的检出限均为0. 15μ/ml,线性关系0-4μg/ml,灵敏度ε1. 65×10⁴L·cm^-1 ·mol^-1 ,实际样品分析结果与原子吸收法和手工比色法接近.更多还原

【Abstract】 In this paper,the reverse flow injection analysis of theiron speciation in tap water,river water and urban wastcwater is presented.The sum of the recording double peak is used as basis of quantitative analysis.The detection limit of Fe（Ⅱ）and Fe（Ⅲ）is 0. 015 μg/ml.The linear relation is 0-4μg/ml.The sensitivity ε1. 65×10⁴1 cm^-1 ·mol^-1 .The results of the practical sample.analysis approach the results of atomic absorption spectroscopy and the colorimetric analysis method.更多还原
