补充资料：活性炭
| 活性炭 activated carbon 经过活化理的黑色多孔的固体炭质。一般呈粉状、粒状或丸状，主要成分为碳，还含少量氧、氢、硫、氮、氯。早期生产活性炭的原料为木材、硬果壳或兽骨，后来主要采用煤，生产方法有：①蒸汽、气体活化法。利用水蒸气或二氧化碳在850～900℃将碳活化。②化学活化法。利用活化剂放出的气体，或用活化剂浸渍原料，在高温处理后都可得到活性炭。 活性炭具有微晶结构，微晶排列完全不规则，晶体中有微孔（半径小于20  ［埃］＝10-10米）、过渡孔（半径20～1000 ）、大孔（半径1000～100000 ），使它具有很大的内表面，比表面积为500～1700米2／克。这决定了活性炭具有良好的吸附性，可以吸附废水和废气中的金属离子、有害气体、有机污染物、色素等。工业上应用活性炭还要求机械强度大、耐磨性能好，它的结构力求稳定，吸附所需能量小，以有利于再生。活性炭用于油脂、饮料、食品、饮用水的脱色、脱味，气体分离、溶剂回收和空气调节，用作催化剂载体和防毒面具的吸附剂。 |
