| 摘 要： | 系统地研究了电气石晶体微粉的粒度、质量分数及环境条件(pH值、温度、搅拌情况)对盐酸溶液pH值、电导率的影响,采用X射线衍射仪和红外光谱分析仪分析了电气石的作用原理.结果表明,在酸性条件下电气石微粉没有发生晶型变化,利用其永久极化、表面吸附和离子交换来调节溶液pH值和电导率.本文的实验结果为电气石晶体微粉在水处理、保健纺织品等方面的应用奠定了基础.

| Abstract: | The effects of the particle diameter,concentration of tourmaline and environmental conditions (pH,temperature and stirring)on pH and conductivity of acidic solution are systematically studied.Its reaction princi- ples are investigated by using X-ray diffraction(XRD)and fourier transformed infrared spectroscopy(FTIR).The ex perimental results show that,pH and conductivity is adjusted by perpetual polarization,surface adsorption and ion ex change of tourmaline in acidic solution,and no transformation of crystal is observed.The present research provides a base for the applications of tourmaline in water treatment and healthcare textile. |
