Modified biochar and modification method and application thereof |
| abstract |
The invention relates to the technical field of preparation and application of modified biochar, in particular to a method, a material and application for modifying biochar by utilizing supercritical carbon dioxide. The invention provides a method for modifying biochar by using supercritical carbon dioxide, which comprises the step of placing the biochar in a supercritical carbon dioxide reaction kettle for reaction to obtain the biochar modified by the supercritical carbon dioxide. The method is simple, environment-friendly, low in cost and easy to realize industrial popularization and application. The prepared modified biochar has a large specific surface area and a large pore volume, and the biochar is rich in surface functional groups and can effectively remove heavy metal ions in an aqueous solution. |
