| Abstract: | Lignin separated from the kraft pulp mill black liquor was used to make active carbon by adding ZnCl 2 and CaCl 2 together as activating agent. Then the active carbon was used to dispose synthesis wastewater of pulp mill by adsorbing. The results are as follows: a high yield (over 50%) and low ash (just 0 113%) active carbon is gained. The adsorption capability of this carbon is almost equal to commercial product active carbon. Thereby it reduces the discharge of black liquor greatly. |
