Tóm tắt

Một loại hydrogel hạt đã được chuẩn bị trong điều kiện môi trường với chitosan làm xương sống, axit acrylic làm monome, và axit ascorbic/hydrogen peroxide (Vc/H2O2) làm chất khởi đầu redox, sau đó được liên kết chéo với ion Fe3+. Fe3+-hydrogel thu được đã được thử nghiệm trong quá trình khử xúc tác 4-nitrophenol (4-NP), với nhận định rằng trong sự hiện diện của NaBH4 và môi trường trơ, 5 mg/L 4-NP có thể được khử hoàn toàn bởi Fe3+-hydrogel trong vòng 30 phút. Ngoài ra, Fe3+-hydrogel cho thấy khả năng tái sử dụng xuất sắc trong mười chu kỳ xúc tác liên tiếp.
