Abstract

Effects of nano-materials on 17O NMR line-width of water clusters have been measured. Different water samples were prepared by adding nano-materials into distilled water and tap water. The average particle size and distribution of nano-materials were characterized, meanwhile, the ions, pH values, total dissolved solids (TDS) and 17O NMR line-width of different water samples were also tested. The effects of time and temperature on 17O NMR line-width of water sample prepared by adding nano-materials into tap water (pH = 8.3) were analyzed as well. The experimental results showed that the particle size distribution of the nano-materials is from 1 to 300 nm, the average particle size is 95.5 nm and the median particle size is 44.7 nm. The nano-materials were mainly composed of calcium. After adding moderate nano-materials into different water samples, the 17O NMR line-width of distilled water decreased from 59 Hz to 44 Hz and the tap water decreased from 113 Hz to 53 Hz. The 17O NMR line-width of water sample prepared by adding a certain amount of nano-materials into tap water (pH = 8.3) is almost the same after 42 days, and the value keeps nearly unchanged as the temperature increases from 30 C to 85 C.
