Research of Decoloring Effect on Active Charcoal to the Single Dyestuffs

This paper has found out the optimum condition of absorbing the single dyestuffs of active charcoal through the experiment which makes the decolouring rate more than 97%. It also discusses the decolouring and absorbing mechanism from the structure of active charcoal and offers the effective basic data for further study of dealing with the printing and dying waste water with the active charcoal.
