通过模拟生物矿化过程，利用CO2缓慢扩散，在硫酸软骨素和十二烷基苯磺酸钠二元体系中，与富集在有机/无机界面的钙离子相结合，合成了碳酸钙晶体。系统地研究了室温下各种因素对碳酸钙晶体形貌和晶型的影响，利用粉末X-射线衍射（ XRD）、扫描电子显微镜（ SEM）等对所得的碳酸钙晶体进行了形貌与结构表征。结果显示，在不同浓度比下的硫酸软骨素和十二烷基苯磺酸钠二元体系或在不同时间下，生成的碳酸钙都具有不同的晶体结构和形貌。%By simulating biomineralization processes , calicium carbonate cystallites with different morphologies are synthesized using enriched Ca2+at organic-inorganic interfaces with slow diffuse CO2 gas in a system of Chondroitin sulfate/sodium dodecyl-benzenesulfonate.The effects of various experimental parameters on the morphologies and polymorphs of CaCO 3 particles are sys-tematically studied at room temperature .The results revealed that samples synthesized in different concentration ratios between sodi-um dodecylbenzenesulfonate and chondroitin sulfate results in different crystal structures and morphologies .
