近年我厂陆续开发了多种新型重整催化剂 ,这些新型重整催化剂的微量杂质硅 ,铁 ,钠 ,钙对其活性有严重影响 ,必须严格控制。为此我们利用ＰＥ2 0 0 0ＩＣＰ标准加入法 ,配制单点标样校准谱线强度 ,利用仪器自动扣除背景的方法测定各元素浓度 ,本方法同时测定多个元素 ,快速 ,简 In recent years, our factory has developed a series of new reforming catalysts. The trace impurities of these new reforming catalysts, such as silicon, iron, sodium and calcium, have a serious impact on their activity and must be strictly controlled. To this end, we use PE2 0 0 0 ICP standard addition method, the preparation of a single point calibration standard calibration curve intensity, the instrument automatically subtracts the background of the method of determination of each element concentration, the method of simultaneous determination of multiple elements, fast, simple
