摘要
在草酸钙过饱和溶液中,利用十八胺和硬脂酸Langmuir-Blodgett(LB)多层膜为模板,文章研究了草酸钙(CaOxa)在LB膜上的结晶行为,采用X射线衍射(XRD)和金相显微镜等技术对CaOxa晶体的结构和形貌进行了表征。实验结果表明,在中性溶液中可以形成一水草酸钙(CaC_2O_4·H_2O,COM)和二水草酸钙(CaC_2O_4·2H_2O,COD)混合晶体,而在同样条件下,十八胺LB膜上只形成COD晶体。
In the supersaturated calcium oxalate solution,the crystallization behavior of calcium oxalate(CaOxa)on LB film is studied by using octadecylamine and Langmuir-Blodgett(LB)multilayers with stearic acid as the template.The structure and morphology of CaOxa crystal are characterized by X-ray diffraction(XRD)and metallographic microscope.The experimental results show that mixed crystals of calcium oxalate monohydrate(CaC2O4·H2O,COM)and calcium oxalate dihydrate(CaC2O4·2H2O,COD)can be formed in neutral solution.Under the same conditions,form a COD crystal.
