Abstract
Since coal gangue can destroy the environment, we aim at improving coal gangue to absorbing material by changing it in different temperature and chemical liquor. Base on the microstructure and the adsorption experiment, we detect microstructure and absorption property of improved coal gangue. The microstructure experiment shows that the average pore size and specific surface area of improved coal gangue appear distinguish obviously as the increasing of chemical liquor pH value and temperature. Absorption experiment shows that the absorption capacity of improved coal gangue decrease as the chemical liquor pH value increase, increase as the temperature increase. The adsorption capacity of improved coal gangue increases with an increase of average pore size and specific surface area.
