Ca2 + ions from the reactants attended to be absorbed in the diffusion dilayer by the so3 - anion . calcium ions could compress the diffusion dilayer and reduce the aggregation number of aot molecular because of the higher charge density . the absorbance of ca2 + ions change of phase diagram of system and water core diameter 反应试剂溶液中的ca ~ ( 2 + )离子倾向于被吸附在aot极性头基的- so _ 3 ~ -阴离子附近，压缩了极性头基水解产生的扩散双电层，使得aot分子的聚集体变小，也使得处于束缚状态的水分子数量减少。
