宝钢电炉纯水钼系缓蚀剂及铜和铝的联合测定

Determination of the Molybdenum Corrosion-inhibitive Drug,Copper and Aluminum in the Pure Water System for Baosteel's EAF

建立了等离子发射色谱法对钼系缓蚀剂和电炉纯水中的铜、铝离子进行联合测定的方法。利用等离子发射光谱通过对钼的分析间接测定钼系缓蚀剂的含量 ,同时对系统中的铜、铝进行测定 ,使方法在准确反映电炉纯水系统钼系缓蚀剂的浓度变化的同时 ,跟踪系统使用的铜材、铝材的腐蚀情况。该方法在宝钢电炉纯水成功应用 ,并已在宝钢炼铁厂、炼钢厂等七个同类系统中推广应用。

A new analysis method of detecting the molybdenum corrosion-inhibitive drug,copper and aluminum in pure water system for electric arc furnaces (EAF) with ICP-AES has been developed.The method can detect the molybdenum corrosion-inhibitive drug,copper and aluminum at the same time.The change in concentration of the molybdenum corrosion-inhibitive drug and the corrosion of copper and aluminum materials of water system can be known.This method has been successfully applied to Baosteel EAF pure water system.It is also widely used in Baosteel's ironmaking,steelmaking and other 5 departments.
