An attempt to enhance the adsorption capacity of biochar for organic pollutants - Characteristics of CaCl biochar under multiple design conditions.

Activators affect the physical and chemical properties of carbon products. However, the effects of different activation mechanisms and pyrolysis conditions on the properties of carbon products still need to be explored. In this study, we obtained a new biochar by impregnation of reed powder with an alkali metal salt (CaCl) under a specific pyrolysis procedure and pyrolysis conditions.

Insights into olation reaction-driven coagulation and adsorption: A pathway for exploiting the surface properties of biochar.

In this study, characterization of biochar for the efficient removal of cadmium was investigated. Biochar has a specific distribution of functional groups on its surface and has a natural electronegativity. Using carbonate as an olation reagent, the biochar coagulates with the olation reaction products.

Study on the influencing factors of natural pectin's flocculation: Their sources, modification, and optimization.

Natural pectin, derived from fruit residue, presented a certain flocculation performance in previous studies. However, the process of extraction and treatment affected the flocculation performance considering the uncontrollable chemical composition and the molecule structure. In this study, degree of esterification (DE), degree of amidation (DA) were used as the internal factors affecting flocculation performance.
