摘要：
The present disclosure relates to improved processes for preparing modified lignite by reacting raw lignite with a source of magnesium (Mg2+) ions and a source of calcium (Ca2+) ions, washing the modified lignite (e.g., with water), drying, and pyrolyzing the treated lignite, and to the use of such products for phosphorous remediation.
