工业合成盐酸中铁含量分析方法研究

Study on determination of iron content in industrial synthetic hydrochloric acid

对电感耦合等离子体发射光谱法和分光光度法测定工业用合成盐酸中铁含量的方法进行研究。确定了试验条件及试验方法,并对两种方法进行了对比,得出每种方法的适用范围。通过试验,认为电感耦合等离子体法更适合目前国内工业合成用盐酸铁含量的测定,并且准确度更高。

In this article,the inductively coupled plasma emission spectrometry and spectrophotometer method for the determination of iron content in industrial synthetic hydrochloric acid were studied.The two methods were compared and the applicable range of each method was obtained.The experimental results showed ICP method was more suitable for the determination of ferric hydrochloric acid content in domestic industry and had higher accuracy.
