Abstract

In this paper, nanomaterials ZnxMn(1-x)Fe2O4 have been prepared by the hydrothermal process, applied in the degradation of basic fuchsin in the presence of H2O2 agent. Factors affecting basic fuchsin degradation over ZnxMn(1-x)Fe2O4 catalyst were investigated including material synthesis conditions, catalytic mass and temperature. The results indicated that the conditions for the synthesis of ZnxMn(1-x)Fe2O4 nanomaterials affect basic fuchsin degradation. The first order kinetic equation is suitable for describing this basic fuchsin degradation. The activation energy of the basic fuchsin degradation was determined to be 14.37 kJ/mol.
Keywords: Basic fuchsin, ZnMnFe2O4 nanomaterial

Tóm tắt

Trong nghiên cứu này, vật liệu nano ZnxMn(1-x)Fe2O4 được tổng hợp bằng phương pháp thủy nhiệt, ứng dụng phân hủy basic fuchsin khi có mặt tác nhân H2O2. Các yếu tố ảnh hưởng đến quá trình phân hủy basic fuchsin trên xúc tác ZnxMn(1-x)Fe2O4 đã được khảo sát gồm điều kiện tổng hợp vật liệu, khối lượng xúc tác và nhiệt độ. Kết quả nghiên cứu chỉ ra rằng điều kiện tổng hợp vật liệu nano ZnxMn(1-x)Fe2O4 ảnh hưởng đến khả năng phân hủy basic fuchsin. Phương trình động học bậc 1 phù hợp để mô tả quá trình phân hủy basic fuchsin trên xúc tác ZnxMn(1-x)Fe2O4 khi có mặt tác nhân H2O2. Năng lượng hoạt hóa của phản ứng phân hủy basic fuchsin xác định được là 14,37 kJ/mol.
Từ khóa: Basic fuchsin, ZnxMn(1-x)Fe2O4
