摘要
研究使用电感耦合等离子体发射光谱法测定炼钢含铝预熔性渣洗料中钙、镁、硅、铝氧化物的分析条件以及处理样品的方式方法,为便于区别金属铝和三氧化二铝,创建了 一种新型的仪器分析方法.由于试样中金属铝的存在,采用先酸溶再碱融的处理方式,并采用配置相似基体的方法消除基体干扰.研究了渣洗料的溶样过程、仪器分析参数的选择、基体的干扰消除等对分析结果影响,在优化仪器分析参数和分解试样实验过程中,试样分析结果相对标准偏差远小于1.0％,分析结果准确度和精密度都很高.因此,该方法可取代化学分析法,是一种准确、快速的仪器分析方法.
Abstract
The analytical conditions of calcium,magnesium,silicon and aluminum oxides in aluminum-containing premelted slag washes by inductively coupled plasma atomic emission spectrometry and the methods of sample treatment were studied.A new instrumental analysis method was created to solve the difference between aluminum and aluminum oxide.The sample was treated with acid dissolution-alkali fusion,and the matrix interference was eliminated by matrix matching method.The influence of sample dissolution method,the selection of instrumental analysis parameters and the elimination of matrix interference were investigated.Under the optimized instrumental parameters and sample decomposition experiment,the relative standard deviation of sample analysis result was far less than 1.0％.The accuracy and precision of the analysis results were very high.The method takes the place of chemical analysis.It is an accurate and rapid instrumental analysis method.
