Trong nghiên cứu này, quá trình Fenton điện hóa dị thể sử dụng xúc tác manganese trên than hoạt tính có nguồn gốc từ bã mía (MnFe2O4/C) để loại bỏ thuốc nhuộm methyl orange trong nước thải mô phỏng. MnFe2O4/C được tổng hợp bằng phương pháp tẩm-đồng kết tủa và được xác định các đặc tính bằng kính hiển vi điện tử quét (SEM), phổ kế tia X tán xạ năng lượng (EDS), nhiễu xạ tia X (XRD). Mô hình Fenton điện hóa sử dụng điện cực than chì được áp dụng để thử nghiệm đánh giá hiệu quả loại bỏ methyl orange trong điều kiện pH trung tính. Ảnh hưởng của các yếu tố khác nhau như dòng điện sử dụng, hàm lượng chất xúc tác, nồng độ methyl orange ban đầu đã được nghiên cứu.
