I、引言催化剂中硅的分析,长期以来我们采用化学分析法,该法流程长、手续繁。而光谱分析法手续简便,快速。但硅元素光谱灵敏度低。得不到一定谱线强度,因此,分析结果仍然不理想。为了提高硅元素谱线的强度,我们利用分馏法把硅元素直接从催化剂成品,原科试样中分馏出来,而后进行光谱分析。经我们对硅元素在催化剂的成品,原料 I. INTRODUCTION The analysis of silicon in catalyst has long been done by chemical analysis, which has a long process and complicated procedures. The spectral analysis method is simple and fast. However, the spectral sensitivity of silicon is low. The spectral intensity can not be obtained, therefore, the analysis result is still not satisfactory. In order to improve the intensity of the silicon element spectrum, we use fractionation to directly fractionate the silicon element from the catalyst product and the original sample, and then perform spectral analysis. After our silicon on the catalyst in the finished product, raw materials
