链状与环状多糖调控caco3的仿生合成
, PP. 50-54
Keywords: 可溶性淀粉,β环糊精,晶体形貌,碳酸钙
Abstract:
以可溶性淀粉、β环糊精及十二烷基硫酸钠（sds）为模板，在cacl2、na2co3体系中调控合成caco3晶体.研究了不同形貌caco3晶体成型原因.分别用红外光谱（ftir）、x射线衍射仪（xrd）、扫描电镜（sem）等技术对晶体的形貌和结构进行了观察和表征.结果表明：可溶性淀粉溶液中5d后得到以球霰石为主的球形caco3;环糊精溶液中5d后得到以球霰石为主的caco3层状聚集体,随着结晶时间的延长,产物中球霰石逐渐向方解石转化，sds的加入加快了球霰石向方解石的转化速度.
