Effluent discharged from industry usually contains large amount of organic dyes,which need to be treated properly to avoid environment pollution.Adsorption by porous carbon is an efficient way to purify effluent with dyes.In this paper,porous carbon obtained from chrome leather(CLPC) was prepared and used as an adsorbent of dyes.Its adsorption performance for methylene blue(MB) was investigated and the adsorption mechanism was studied.The results show that the pH value,initial concentration and adsorption t...
