活性炭是一種經(jīng)特殊處理的炭，將有機原料（果殼、煤、木材等）在隔絕空氣的條件下加熱，以減少非碳成分（此過程稱為炭化），然后與氣體反應，表面被侵蝕，產(chǎn)生孔發(fā)達的結(jié)構 （此過程稱為活化）。由于活化的過程是一個觀過程，即大量的分子碳化物表面侵蝕是點狀侵蝕 ，所以造成了活性炭表面具有無數(shù)細小孔隙。活性炭表面的孔直徑大多在2～50nm之間，即使是少量的活性炭，也有巨大的表面積，每克活性炭的表面積為500~1500m2，活性炭的一切應用，幾乎都基于活性炭的這一特點。

 

 二是要看蜂窩活性炭產(chǎn)品所產(chǎn)生的氣泡，如果產(chǎn)生的氣泡越多則產(chǎn)品的質(zhì)量就越好。我們可以做一個小實驗，將一小把蜂窩活性炭產(chǎn)品投入水中，由于水滲透的作用，水會隨之浸入活性炭的孔隙中，以此來讓孔隙中的空氣排出，從而產(chǎn)生一連串的極為小的氣泡，在水中拉出一條細小的氣泡線，同時又發(fā)出了茲茲的氣泡聲，看著十分有趣。如果這種現(xiàn)象發(fā)生的很劇烈的話，而且持續(xù)的時間越長，那么就證明蜂窩活性炭產(chǎn)品的孔隙結(jié)構非常發(fā)達，就是蜂窩活性炭的吸附性越好的表現(xiàn)。
  
  The two is to look at the honeycomb activated carbon products produced by the bubble, if the bubble is more the better the quality of the product. We can do a little experiment, a handful of honeycomb activated carbon products into the water, because the water penetration effect, water will be immersed in the pores of activated carbon, so the pore in the air, resulting in a series of very small bubbles, pulled out a tiny bubbles lines in the water, at the same time also issued Zizi bubble sound, looked very interesting. If this phenomenon is very serious, and the longer the duration, then it is proved that the honeycomb activated carbon product pore structure is very developed, that is, the better adsorption performance of honeycomb activated carbon.
