Investigation on the mechanism of water activated via tourmaline powder

Herein, the mechanisms of tourmaline powder activating water were discussed via the performance of water cluster. The result suggested that the performance of water were improved by tourmaline powder. The surface tension 72.19 mN/m, dissolved oxygen 9.57 mg/L, and conductivity 0.53 us/cm of activated water were obtained at D50 of tourmaline powder 0.79 μm, dosage of tourmaline powder 20 g/L, processing time 10 min, and processing temperature 17 °C. Besides, assisted by the tourmaline powder, the full width at half maxima (FWHM) of 17O in the nuclear magnetic resonance (NMR) of water diminished from 1485 Hz to 533 Hz. The polarization electric field of tourmaline improved the water temperature to weaken and break the hydrogen bond. Based on the various infrared active vibrational bonds of tourmaline, the molecules resonate of water were promoted by the far-infrared radiation to cut off the hydrogen bonds and improve the activity of water.
