电感耦合等离子体发射光谱法测定铝合金中钛、锆、铈、铁、硅

Determination of Titanium, Zirconium, Cerium, Iron, Silicon in Aluminium Alloys by Inductively Coupled Plasma Emission Spectrometry

本文采用ICP-AES法测定了铝合金中钛、锆、铈、铁、硅,其测定含量在0.x％～0.0x％之间,回收率一般为95％～106％,相对标准偏差1.2％～8％。所拟定的分析方法,经几种铝合金标准样品验证,其准确度和精密度较高。符合日常分析的要求。分析速度简便快速。

In this paper the determination of titanium, zirconium, cerium, silicon in the aluminium alloys by ICP-AES was suggested. The recovery was 95%-106%with relative standard deviation 1.2%-8%, when the content determined was in the range of 0.x%-0.0x%.The results for determination of mentioned elements in some aluminium alloy standard samples by entitled method hare demonstrated that this method has high accuracy and precision. It could be used in routine analysis operated easily and rapidly.
