A chitosan fiber as green material for removing Cr(VI) ions and Cu(II) ions pollutants

Abstract The application shell uses cellulose as a green and recyclable fiber material, which has great value in the field of water treatment environment. Varying factors, including pH value, dosage of CS, reaction time and original Cr(VI) ions and Cu(II) ions were studied to investigate the Cr(VI)...
