摘要
以CO32-型镁铝LDHs为前体,采用了焙烧复原法和离子交换法两种不同的插层方法,成功地将水杨酸根阴离子插入到LDHs层间,并用FTIR、XRD、TG-DA和分子荧光光度计等手段对样品进行了表征。结果表明,离子交换法在pH=4条件下的插层效果要比焙烧复原法效果显著;同时,水杨酸根阴离子插入到层间后,因受到LDHs层间静电力、氢键、层板相互作用力等影响,其荧光发射波长发生蓝移,且其发光强度明显减弱。
Mg-Al-carbonate hydrotalcite （LDH） was synthesized by hydrothermal method and was Salicylate was successfully intercalated into LDH by calcined method and anion exchanged method. Th were characterized by XRD,FTIR ,TG-DTA and Fluorometry. The results show that the effect o used as precursor. e samples obtained f anion exchanged method of intercalation with pH=4 was better than calcined method. After Salicylate was intercalated into the interlayer, was affected by interaction of the host layers and the guests. As a result, the emission wave of the Salicylate moved to lo wave, and the intensity became weak.
