| The advancement of technology and the development of society create more social value, but it also does harm to the environment and health as well. How to use the method of low price and high efficiency to solve these problems attracts people's attention. Tourmaline as a kind of natural mineral materials, not only has excellent piezoelectricity, pyroelectricity and permanent polarity, but also has the performance of far-infrared emission and releasing negative ions, these properties can be applied in the field of environment and health. China as one of the few nations of tourmaline-rich, has abundant resources, however, China is in a weak position in the development and utilization of the wave of tourmaline. Therefore, to enhance the application of tourmaline has great significance in the field of environment.This work was focused on the application of tourmaline from Inner Mongolian, in addition, also studied the tourmaline from Hebei. First, studied the preparation process of tourmaline powder and tourmaline ceramisites. Discussed the variation of related properties of tourmaline by XRD, Laser particle size analysis, IR, SEM and Far-infrared emissivity test, and analysed the reasons caused by these variations. Based on these experimental data, we studied the tourmaline from the aspects of activated water, pH value adjustment, adsorption of heavy metal ions and the effect on the TiO2 photocatalytic activity, and discussed the mechanism.The results showed that the phases of two groups of tourmaline both were Schorl-Dravite. We obtained superfine tourmaline powder about 0.47μm using the wet milling process at the ratio of tourmaline: zirconium ball: deionized water equal to 4:47:10. From the test spectra it can be found that the XRD diffraction peaks broadened IR vibration band blue-shifted, and the far-infrared emissivity improved, these results were attributed to the surface effect brought by particles continue to being refined in the process of milling. We also obtained the tourmaline ceramisites satisfied the experimental requirements at the condition of 600℃calcined and borax as a flux. Calined tourmaline powder at 400℃and 600℃have caused shrinkage of cell volume and improvement of far-infrared emissivity.NMR be used to characterize the clusters of water molecule in the experiment of activated water. The effect of tourmaline particle size, tourmaline morphology and the laying time of activated water on the 17O NMR FWHM of water can be discussed by the direct action of tourmaline and water. The results showed that the 17O NMR FWHM of water get narrower with the decrease of tourmaline particle size,especially addition of tourmaline ceramisites, so ceramisites have widely application due to its fixed shape and easy recovery. It can be found from tracking test of activated water, the 17O NMR FWHM of water still below 100Hz after 480 h, water molecule still maintained good activity, suggesting the potential application value of tourmaline in water activation.In the experiment of pH value adjustment, studied the effect of tourmaline particle size, tourmaline morphology, tourmaline heat treatment temperature, the recycling times of tourmaline and laying time on the pH value of water. We concluded that tourmaline changed the pH value of water and made it stable at 8.8. The smaller of the tourmaline particle size, the greater change of pH value of water, but the effect on acid solution was greater than alkali solution under the influence of surface hydroxylation of tourmaline. It was found from the tourmaline heat temperature, pH value reach to maximum when tourmaline was heated to 800℃, this is related to the surface property and spontaneous polarity, however, the effect of ceramisite on pH value of water is better than powder in this process. The water still maintained alkaline after tourmaline was used five times, demonstrating that using tourmaline to adjust pH value of water not only simplied the process and improved the efficiency but also saved raw materials and reduced pollution.After adsorption treatment of different particle size tourmaline, the residual concentrations of Cu2+ and Zn2+ in the solution were tested by atomic adsorption spectrophotometer, and the results show: The smaller particle size of tourmaline, the better adsorption effect. Under the electric field, the removal rate of Cu2+ and Zn2+ reach to 99.79 % and 99.96 %, respectively, Cu2+ and Zn2+ almost all have been removed, it made the Cu2+ and Zn2+ concentrations of solution were much less than primary standard of national effluent standards.Titania composite powder containing tourmaline were prepared by a sol-gel method in the experiment. From XRD pattern, it was found that the composite powder was anatase phase of TiO2, when the composite powder was calcined at 600℃for 2 hours. From the results of fluorescence emission intensity and photocatalytic degradation of methyl orange of composite powder, it exhibited the best photocatalytic effect when the tourmaline particle size was 0.47μm and the doping concentrations was 6 %. This demonstrated that more electron can be captured by tourmaline in this condition and controlled the recombination probability of photo-generated electron and photo-generated hole, therefore, improved the utilization of photo-generated hole.
