Abstract

In recent years, low-cost and high-performance properties of adsorbents have become a strong demand in adsorbents preparation. Biochar and lignin present great potential for wastewater treatment due to their unique physicochemical properties, and were found to be promising candidate materials in pollutant removal by adsorption in the practical application process. Researchers have adopted various methods to modify biochar and lignin to enhance their adsorption efficiency. In this study, the source, preparation methods, and structural features of biochar and lignin are thoroughly reviewed. The latest progress of biochar-based adsorbents (BBAs) and lignin-based adsorbents (LBAs) in wastewater treatment were reported and comparatively analyzed. The adsorption mechanisms between BBAs/LBAs and various pollutants were analyzed. Besides, the potential and challenge of BBAs and LBAs in pollution remediation and industrial application were comprehensively discussed. To accelerate the development of LBAs and BBAs in wastewater treatment, further explorations are necessary for the preparation of the novel LBAs/BBAs, exploring the adsorption mechanism and industrial application.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
