摘　　要：根据生物矿化原理,以PSSS(聚苯乙烯磺酸钠)为模板,开展Mg^( 2+)/L-谷氨酸协同作用对PSSS为模板合成碳酸钙晶体的调控探究。采用扫描电子显微镜(SEM)、X射线粉末衍射仪(XRD)等对所得产物进行表征。结果表明,实验得到了各种不同形态的碳酸钙晶体,通过比较发现,Mg^(2+)和L-谷氨酸的加入对碳酸钙晶型与形貌构成产生影响。This article discusses the regulation of PSSS(sodium polystyrene sulfonate)as a template,magnesium ions as inorganic ions,and Mg^(2+)/L-glutamic acid synergistic effect on the synthesis of calcium carbonate crystals using PSSS as a template.The obtained product was characterized by means of scanning electron microscope(SEM)and X-ray powder diffractometer(XRD).The result showed that various forms of calcium carbonate crystals were obtained.Through comparison,we found that the addition of Mg^(2+)and L-glutamic acid affects the crystal form and morphology of calcium carbonate.
