Implication

Experimental tests reveal over 75% dye removal in a recirculating photoreactor, indicating effective visible light activation of ferrioxalate systems.

Key Points

  • Widespread degradation of Toluidine Blue achieved with ~75% removal in 1 hour under visible light.
  • Optimal conditions included pH 4 and a 10:1 molar ratio of oxalate to Fe(III).
  • Recirculating batch-loop photochemical setup utilized both LED and fluorescent light sources for comparison.
  • Findings underscore the potential of ferrioxalate systems, while highlighting needs for further investigation into by-products and mineralization.
