天然矿物电气石产生空气负离子性能研究

Study on negative-air-ions properties of natural mineral tourmaline

以桂林电气石和阿尔泰电气石为原料，研究了它们产生的空气负离子性能。用红外光谱仪、X射线衍射仪、扫描电镜对这两种电气石进行了分析表征。结果表明：桂林电气石为铁电气石，平均能够产生空气负离子692个／cm^3，相对增加空气负离子394个／cm^3；阿尔泰电气石为铁镁电气石，平均能够产生空气负离子935个／cm^3，相对增加623个／cm^3；两种电气石吸收或辐射的主要红外波段基本一致，都存在比较多的红外活性键，但是阿尔泰电气石在7．39gm处多出现了一个B-O键辐射或吸收峰。

Tourmalines from Guilin and Aertai area were researched on negative-air-ions properties and characterized by IR, XRD and SEM. The results showed tourmaline from Guilin was Fe-tourmaline, which could produce average 692 negative air ions and relative increasing 394 negative air ions per cubic centimeter; that tourmaline from Aertai was ferridravite, which could bring average 935 negative air ions and relative increasing 623 negative air ions per cubic centimeter; meanwhile, both of tourmalines were basically consistent in main infrared wavelength absorbed or eradiated by tourmalines and existed in quite a few infrared active bond, but tourmaline from Aertai appeared an added absorbed or eradiated peak of B-O bond in the wavelength of 7.39μm.
