二是要看蜂窝活性炭产品所产生的气泡，如果产生的气泡越多则产品的质量就越好。我们可以做一个小实验，将一小把蜂窝活性炭产品投入水中，由于水渗透的作用，水会随之浸入活性炭的孔隙中，以此来让孔隙中的空气排出，从而产生一连串的极为小的气泡，在水中拉出一条细小的气泡线，同时又发出了兹兹的气泡声，看着十分有趣。如果这种现象发生的很剧烈的话，而且持续的时间越长，那么就证明蜂窝活性炭产品的孔隙结构非常发达，就是蜂窝活性炭的吸附性越好的表现。
  
  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.

活性炭是一种经特殊处理的炭，将有机原料（果壳、煤、木材等）在隔绝空气的条件下加热，以减少非碳成分（此过程称为炭化），然后与气体反应，表面被侵蚀，产生孔发达的结构 （此过程称为活化）。由于活化的过程是一个观过程，即大量的分子碳化物表面侵蚀是点状侵蚀 ，所以造成了活性炭表面具有无数细小孔隙。活性炭表面的孔直径大多在2～50nm之间，即使是少量的活性炭，也有巨大的表面积，每克活性炭的表面积为500~1500m2，活性炭的一切应用，几乎都基于活性炭的这一特点。
