摘要
通过模拟生物矿化过程,把表面活性剂十二烷基苯磺酸钠(SDBS)加入到乙二醇和水混合溶液中,搅拌一段时间后加入一定浓度的Na2CO3水溶液,然后分别于20?、40?、60?、80?下缓慢滴加CaCl2水溶液进行反应。XRD和TEM发现,不同温度下生成的碳酸钙具有不同的晶体结构和形貌,分析了其可能的成因。
In this paper, by modeling biomineralization processes, adding surfactant sodium dodecylbenzensulfonatc （SDBS） into mixed solution of glycol and water. After agitating a period of time, 0.3mol/L Na2CO3 solution was given into SDBS/glycolAvater system, then 0.3mol/L CaCl2 was dribbled slowly into the mixed solution at different temperature （20℃, 40℃, 60℃, 80℃） to react with Na2CO3 mixed solution. XRD and TEM found that samples synthesized in different temperature had different.crystal structures and morphologies. And the possible reasons were analyzed.
