摘要
为充分利用电气石的天然电极性和远红外发射特性,利用核磁共方法研究了电气石对水分子团簇结构的影响。实验结果表明:电气石能够降低水分子的17O核磁共振(NMR)半高宽,并且降低的幅度与电气石的粒径呈正相关关系;若将电气石烧成陶粒后,则其对水分子的17ONMR半高宽降低的幅度更大。另外活化水的时效性测试结果表明,活化水在放置480h之后,仍然可以保持良好的活性。
In order to make full use of natural polarity and far-infrared radiation characteristics of tourmaline,effect of tourmaline on the structure of water clusters was studied by the method of nuclear magnetic resonance.It is indicated that tourmaline reduced ^17O nuclear magnetic resonance（NMR）full width at half maximum intensity（FWHM）of water molecular,and the reduction amplitude is positive correlation with the size of tourmaline.When tourmaline is calcined to ceramisite,its effect on ^17O NMR FWHM of water molecular is more obvious than that of tourmaline powder.From the aging test of activated water,it can be found that the water still maintained good activity after 480 hours.
