摘要： Artificial humic acid (A-HA) produced from biowaste via hydrothermal conversion demonstrates as a promising advanced soil organic matter supplement. However, its low production yield, and poor physicochemical properties, such as high molecular weight and inert function groups, limit the practical application. This study investigated the potential of green vitriol (GV) on stimulate A-HA production and modify the its qualities. The yield of A-HA increased from 21.87 wt% to 27.84 wt% with a ratio of biomass to GV was 6 at 220 degrees C, while the optimum proportion of A-HA in hydrochar was increased by 13.57 +/- 11.06 wt% compared to the control at a temperature of 280 degrees C and a 3:1 addition ratio. In addition, the A-HA molecular weight decreased, and oxygencontaining functional groups (i.e., hydroxyl and carboxyl groups) increased with GV addition, enhancing its the reactivity and hydrophilicity. The related promotion mechanism was proposed, which the oxidative decomposition and humification of difficult-to-break-down substances facilitated by hydroxyl radical(& sdot;OH) from the Fenton-like reaction of GV with water. This study helpfully presents a novel strategy for promote production of sustainable and high-quality A-HA.
