| 摘 要： | 采用27Al NMR法、渗析法与原子吸收分光光度法,研究了柠檬酸铝(AlCit)溶液中铝的形态及pH值的影响.结果表明,在AlCit溶液中存在两种形态的Al,一种是分子态AlCit,另一种是胶态Al, pH值增加时,分子态AlCit的量减少而胶态Al的量增加.

| Abstract: | The existing state of aluminum in aqueous aluminum citrate(AlCit)solution and the effect of pH value on it are investigated by 27 Al NMR,atomic aborbance spetrum and dialysis.The experimental results show that there are two states of Al in AlCi t solution,one is in molecular state,the other is in colloidal state.When the pH value of solution is increased,the amount of the Al in molecular sta te is decreased,and the amount of the Al in colloidal state is increased gr adually. |
