摘要
凹凸棒石黏土矿因富含有铁等元素限制它的应用。本实验利用超声波的热效应,搅拌作用和强烈振动作用,应用草酸-三氯化钛联合漂白的技术路线,对各地凹凸棒石黏土矿进行除铁漂白。实验结果表明,应用此方法除铁增白效果明显,经除铁增白后的凹凸棒石黏土矿反射率可达56.1%,白度可达71.1%。利用除铁增白后的凹凸棒石黏土矿进行分子筛的合成,并借助IR、XRD、SEM等手段进行表征,结果表明经除铁增白后的凹凸棒石黏土矿能合成出分子筛。
Attapulgite clay has iron impurities, which greatly restrict its application. Using ultrasound thermal, stimng and vibration effects, and oxalicacid and titanium-chloride joint-bleaching technology, the iron removing and bleaching of the attapulgite clay are carried out, The results show that this method is effective, and after iron-removing and bleaching, the attapulgite clay reflectivity can reach 56.1% and the whiteness index can reach 71.1%. Using this attapulgite clay to synthesize zeolite, and tested by IR, XRD and SEM, we find that attapulgite clay can be synthesized into zeolite after iron-removing and bleaching.
