Summary: This study demonstrates the efficient removal of cellulose-reactive anionic dyes using water hyacinth root powder (WHRP) bioadsorbent. By adjusting adsorption conditions such as pH, adsorbent dose, dye concentration, particle size, mixing speed, and temperature, the adsorption performance can be effectively enhanced. The adsorption process exhibits spontaneity and exothermicity in terms of Gibbs free energy and enthalpy, and is controlled by multiple mechanisms.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
