摘要
利用元素分析(EA)、红外光谱(FTIR)、热分析(DSC-TGA)和扫描电镜(SEM)等分析手段对配合物的组成、尺寸和形貌进行分析与表征.采用水热法合成了树叶状的镧(La)-对苯二甲酸(1,4-bdc)二元配合物.结果表明,对苯二甲酸的羧基氧与La3+配位,树叶状配合物的组成为La2(1,4-bdc)2.3H2O,树叶状叶片厚度范围约为1~3μm.
The composition,size and morphology of the La2(1,4-bdc)2·3H2O were characterized by Elemental analysis(EA),Fourier transform infrared spectrum(FTIR),Thermal analysis(DSC-TGA) and scanning electron microscope(SEM),respectively.The leaves shape of lanthanum binary complex of LaCl3·6H2O with terephthalic acid(1,4-benzenedicarboxylic acid,1,4-bdc) was synthesized by hydrothermal method.Results showed that the carboxylate oxygen atoms from terephthalic acid were coordinated with La3+ ions.And the size range of the leaves shape micron complex was 1~3μm.
