Overview

Randomized trial investigates photocatalytic dye removal in wastewater using synthesized nanoflowers, indicating an effective solution.

Key Points

  • This research aims to develop a method for complete removal of textile dyes from wastewater using nanoflower photocatalysts.
  • Synthesis of ZnO, Fe2O3, and MnO2 nanoflowers via ultrasonication-assisted co-precipitation
  • Evaluation of dye removal efficiency in relation to metal ion concentration, pH, and dye concentration
  • Characterization of nanoflowers to confirm surface area and purity
  • MnO2 nanoflowers achieved 90.42% dye adsorption and 93.48% photocatalytic degradation of methylene blue
  • ZnO nanoflowers showed the highest retention of activity after recycling
  • Overall, metal oxide flowers demonstrated high efficiency and scalability for wastewater treatment
