| Abstract | ||
| In the present study, the activation features of phosphoric acid have been investigated using asphalt as the raw material in the production of granular activated carbon. The quality of the prepared carbon was tested by measuring its iodine number and ability to adsorb methylene blue. The density, moisture content, hardness, effective size, and total ash content were also evaluated. The obtained results were compared with a carbon of a commercial grade supplied by the BDH chemical company. The comparison proved that the prepared carbon is of a good quality and comparable to the commercial one. | ||
