Tổng hợp vật liệu CuO/biochar từ hạt nhãn bằng phương pháp thủy nhiệt ứng dụng hấp phụ methyl orange trong nước
Nội dung chính của bài viết
Tóm tắt
Nghiên cứu này trình bày quy trình tổng hợp vật liệu hấp phụ CuO/biochar từ hạt nhãn bằng phương pháp thủy nhiệt, nhằm xử lý chất màu methyl orange (MO) trong nước. Vật liệu được đặc trưng bằng các phương pháp SEM, EDX, XRD, FT-IR và BET. Kết quả phân tích cho thấy CuO được phân bố đồng đều trên bề mặt biochar, góp phần làm tăng diện tích bề mặt riêng và khả năng hấp phụ. Khả năng hấp phụ của vật liệu được khảo sát theo các yếu tố: thời gian đạt cân bằng hấp phụ, pH dung dịch, nồng độ MO và khối lượng chất hấp phụ. Quá trình hấp phụ tuân theo mô hình Langmuir với dung lượng hấp phụ cực đại đạt 227,27 mg/g tại pH = 3 và thời gian cân bằng là 90 phút. Mô hình động học biểu kiến bậc hai phù hợp nhất với dữ liệu thực nghiệm, cho thấy quá trình hấp phụ chịu sự chi phối của cơ chế hóa học. Kết quả cho thấy CuO/biochar từ hạt nhãn là vật liệu hấp phụ tiềm năng trong xử lý nước ô nhiễm chứa phẩm nhuộm anion.
