Optima 8000 DV 光谱仪分析盐水对仪器配置及条件的选择

摘要

The core of ionic membrane caustic soda was the use of ion exchange membrane , and the salt water of the Ca2+, a high content of Mg 2+plasma affected the use of ionic membrane performance , therefore the content of Ca 2+and Mg2 +must be strictly controlled.Based on the analysis with Optima 8000DV, determination of secondary brine in ionic membrane caustic soda process when calcium , magnesium ions content in the best conditions , equipment configuration and analysis in the use of gem orthogonal atomizer , high sensitivity atomizer , low flow atomizer and change after the analysis condition of determining when using a low flow atomizer and radial observation method was the most stable and accurate analysis results.%离子膜烧碱的核心在于离子交换膜的使用，而盐水中的Ca2＋、 Mg2＋等离子含量高使影响离子膜的使用性能，因此必须严格控制其中的Ca2＋、 Mg2＋含量。通过试验，分析用Optima 8000DV测定离子膜烧碱工艺中二次盐水中钙、镁离子含量时最佳的仪器配置和分析条件，在使用宝石正交雾化器、高灵敏度雾化器、低流量雾化器及改变部分分析条件后，确定用低流量雾化器及径向观测方式时具有最稳定、准确的分析结果。
