建立一种以分光光度法测定 SAPO-34分子筛中硅含量的分析方法。以硅和钼酸铵在盐酸介质中形成硅钼黄杂多酸，再以抗坏血酸将硅钼黄还原成硅钼蓝后，对硅含量进行测定。结果表明，体系中硅钼蓝的最大吸收波长为806 nm，绘制的标准曲线在0.1000~6.000 mg/ L 内服从朗伯-比尔定律，所得相关系数为 R2=0.9995。该分析方法用于 SAPO-34分子筛中硅含量的测定，精密度及稳定性良好，操作简单、快速。

To establish a spectrophotometric method determination of SAPO-34 silicon content in molecu-lar sieve analysis method. With silicon and ammonium molybdate formed in hydrochloric acid medium sili-con molybdenum yellow heteropoly acid,using silicon with ascorbic acid molybdenum yellow after reduc-tion of silicon molybdenum blue,for determination of silica content. The results show that the maximum absorption wavelength of silicon molybdenum blue is 806 nm,draw the standard curve of within 0. 100 0~ 6. 000 mg / L to lambert beer’s law,the correlation coefficient R2 = 0. 999 5. The analysis method is used for SAPO-34 on the determination of silicon content in molecular sieve,precision and good stability, simple operation,fast.
