Abstract

Degradation of carbamazepine (CBZ) by two different forms of MnO₂ (δ-MnO₂ and colloidal MnO₂) was studied and compared. The intermediate products in CBZ oxidation at different pH by δ-MnO₂ or colloidal MnO₂ were analysed via LC/MS. Results demonstrated that 1mg/L of CBZ could be completely removed by both δ-MnO₂ and colloidal MnO₂ within 2 hours. Comparing to δ-MnO₂, colloidal MnO₂ was less affected by pH and had better removal of CBZ per unit mass Mn. In total, 7 and 4 kinds of intermediate products were detected in the process of CBZ oxidation by δ-MnO₂ and colloidal MnO₂, respectively. That was because colloidal MnO₂ had stronger oxidizing power, and could omit several oxidation steps producing various intermediates. As a result, CBZ oxidation by colloidal MnO₂ was via a more concise pathway.

Key words： manganese oxide carbamazepine degradation pathway
