简介：微隧道通常在0.3nm的范围与孔指矿物质的结构的隧道到2.0跑。如此的微隧道包括，K在cryptomelane充满的Mn-O八面体隧道，和Si-O和Al-0四角形的分子的筛构造的隧道在沸石由Na和Ca充满了，并且有效地有分子的筛的功能。这里，我们指出自然矿物质的ultra-microchannels与离子的筛的特征在0.3nm下面有孔。矿物质长石的ultra-microchannels，为地球的半团的财务“scrust，因为孔是太小的，大部分被忽略了。在这个工作，我们在场那长石显示离子交换的某个度并且在高、低的温度下面拥有隧道结构的一个特征。在高温度，Na~+能进入长石的隧道。在直到15.9%的长石增加的Na_-O的Thecontent。在中间的温度，Pb~(2+)能也作为离子交换的结果进入长石的隧道，这样带到形成ofPb长石。在房间温度，大约97.94%Cd~(2+)能被移开，Cd长石能被获得。这些现象显示长石的ultra-microchannels的典型效果，它可以为重金属污染和原子废物的处理作为一个潜力被建议。自然矿物质的Theultra-microchannels在移植和交换ofgeomaterials起了特殊作用。一些自然矿物质的微隧道的分子的筛有净化分子的煤气的污染的性质。并且很自然的矿物质的ultra-microchannels的离子的筛能净化离子的水污染。
