Abstract
- To reduce the cost of water treatment reagents, a simplified iron(III) tetraamido macrocyclic ligand compound (Fe<superscript>III</superscript>-TAML) was synthesized with a total yield of 53.3%. For comparison, two second generation Fe<superscript>III</superscript>-TAML catalysts were synthesized. The synthetic route was optimized, and the total yield increased from 30.1% to 49.5%. The catalytic activity of the simplified catalyst for degradation of dye wastewater by hydrogen peroxide was tested and compared with that of the second generation Fe<superscript>III</superscript>-TAML catalysts. The experimental results show that the simplified catalyst has good catalytic activity. At 25 °C, pH = 8, C<subscript>Fe-TAML</subscript> = 50 mg/L, and C<subscript>hydrogen peroxide</subscript> = 1.5 g/L, the decolorization and chemical oxygen demand removal of methylene blue, methyl orange, neutral red, and Rhodamine B dye wastewater were 74.8%–96.1% and 46.9%–63.7%, respectively.
