采用离子交换法将不同组份的十烷基三丁基溴化鳞交换到蒙脱土的层间得到柱撑蒙脱土.用热重分析(TGA)、X-射线衍射(XRD)和傅里叶变换红外光谱法(FTIR)等对其结构进行了表征,并测定其抗菌活性.研究发现柱撑蒙脱土中季鳞盐的热分解起始温度大于210℃,具有较好的热稳定性;季鳞盐含量越高,柱撑蒙脱土的层间距越大,抗菌活性越高.
採用離子交換法將不同組份的十烷基三丁基溴化鱗交換到矇脫土的層間得到柱撐矇脫土.用熱重分析(TGA)、X-射線衍射(XRD)和傅裏葉變換紅外光譜法(FTIR)等對其結構進行瞭錶徵,併測定其抗菌活性.研究髮現柱撐矇脫土中季鱗鹽的熱分解起始溫度大于210℃,具有較好的熱穩定性;季鱗鹽含量越高,柱撐矇脫土的層間距越大,抗菌活性越高.

Pillared montmorillonites were prepared by introducing different content of deeyltribu-tylphosphonium bromide into sodium montmorillonite through ion-exchange method. The structures were studied by thermogravimetric analysis (TGA) methods, X-ray diffraction (XRD) technique and fourier transform infrared (FrIR) spectroscopy. Also the antirnicrobial activity was studiesd. The results showed that the onset temperatrure of the decomposition for quaternary phosphonium salts in pillared montmoril-lonites were all higher than 210℃, and they were preferable thermal stability. The interlayer spacings ofmontmorilonites enlarged and the antimicrobial activity improved with the increase of the content of qua-ternary phosphonium salts in pillared montmorillonites.
