钛硅沸石 UV-Vis 谱的研究

Research on UV Vis spectra of titanium silicalite

研究了以ＴＰＡＢｒ为模板剂合成的ＴＳ－１的ＵＶ－Ｖｉｓ谱，考察了配料方式、模板剂用量、络合剂、酸处理等对２７０～２８０ｎｍ峰强度的影响．研究发现：晶化条件对此峰强度影响不大，模板剂用量有一定影响；采用络合剂和酸处理可显著降低此峰强度．

UV Vis spectra of TS 1 synthesized using TPABr as the templating agent are studied. The influence factors on the strength of the 270-280 nm peak, such as the way to prepare the gel, the amount of template, the complexing agent are also discussed. It has been observed that crystallization condition has little influence on the strength of the peak while the amount of TPABr has some effect. The strength of the peak decreases largely if a complexing agent is used or the zeolite is treated with acid.
