摘要
本文研究了用浓硝酸将２－乙基蒽醌中的硫定量转化成硫酸根，然后用硫酸钡分光光度比浊法间接测定其硫含量的方法。建立的方法简单、快速、实用。试样分析结果表明准确度及精密度均符合要求。
An analytic method was studied and developed to determine the sulfur impurity in catalyst 2-EAQ.The sample was oxidized with concentrated nitric acid, converting sulfure into sulfate,pricipited with barium chloride,the resultant turbidity of barium sulfate was determined with a spectroscope,sulfur content was calculated. This method is simple and fast,yielding accurate result.
