摘要
测试了AlCl3,Al2 (SO4) 3,FeCl3,Fe2 (SO4) 3等对水的1 7O NMR化学位移和半峰宽的影响 ,并利用水1 7O NMR化学位移和半峰宽的变化与氢键的关系 ,分析了AlCl3,Al2 (SO4) 3,FeCl3,Fe2 (SO4) 3等对水缔合的影响 .研究表明 ,AlCl3,Al2 (SO4) 3,FeCl3,Fe2 (SO4) 3等对水缔合有促进作用 ,且Fe3+对水缔合的作用大于Al3+.
The effects of AlCl 3,Al 2(SO 4) 3,FeCl 3 and Fe 2(SO 4) 3 on 17O-NMR chemical shift and line-width of water is tested.It is analyzed that the effect of them on water association by means of the relationship of 17O-NMR chemical shift and line-width of water with hydrogen bond.It is demons- trated that they increase water association.The effect Fe 3+ on promotion of water association is stronger than that of Al 3+.
