2026-09-15 Preparation Method of N,S Co-Doped Hydrothermal Carbon and Its Application in Removing Cr(VI) from Aqueous Solution doi:10.57760/sciencedb.iga.01383 en This patent discloses the preparation method of N,S co-doped hydrothermal carbon and its application in removing Cr(VI) from water, aiming to solve the problem of poor Cr(VI) removal efficiency of traditional carbon-containing adsorbents. Using corn straw powder and thiourea as raw materials, the hydrothermal carbon is prepared via a one-step low-temperature hydrothermal method, and the preparation process is optimized by regulating parameters such as raw material ratio and hydrothermal temperature. This material can be used as an adsorbent to treat Cr(VI)-containing wastewater under specific pH and temperature conditions, with an adsorption capacity of 98.84 mg/g. It can also reduce toxic Cr(VI) to low-toxicity Cr(III), and is suitable for the field of Cr(VI)-containing wastewater treatment.
