This work developed a short-growth-cycle biomass waste (golden needle mushroom roots) to prepare an inorganic adsorbent (activated carbon) through one-step H₃PO₄-activated carbonization. The effects of GNMACs dosage, solution pH value, and carbonization temperature on the removal ability of Cr(VI) were studied. The GNMACs possessed a hierarchical pore structure including micropores, mesopores, and macropores with a specific surface area of 782.641 m<sup>2</sup>/g and an average pore diameter of 5.620 nm. The GNMACs exhibited a Cr(VI) adsorption capacity of 100.95 mg/g. Additionally, the isotherm model and kinetic model results indicated the adsorption of Cr(VI) by GNMACs involved a combination of physical and chemical adsorption. The adsorption mechanism involved electrostatic interaction, redox reaction, and pore filling. Besides, the GNMACs exhibited excellent adsorption performance for Cr(VI) and MO in a binary pollutant solution, and both of them can be totally absorbed within 90 min, indicating the promising application potential for simultaneously removing heavy metals and dyes from textile wastewater. GNMACs maintained a removal rate of 52.60 % after five regeneration cycles.
