Study on Synthesis and Application of HCs5P2W18O62.16H2O to Adsorption of Organic Matter: Methylene Blue | Chapter 13 | New Innovations in Chemistry and Biochemistry Vol. 1

 The dye methylene blue was tested for adsorption by the cesium Dawson heteropolyanion HCs5P2W18O62.16H2O. Adsorption is a critical step in heterogeneous catalysis.

Adsorption can also be used as a separation method to eliminate unwanted colours from industrial waste. The first section is on adsorbent synthesis and characterization. The adsorption-related experimental parameters were then optimised. Finally, the adsorbent's regeneration was investigated. For an MB concentration of 25 mg/L and an adsorbent mass of 0.25 g, the best yield was 88 percent. At 80°C, the regeneration yield was 98 percent. The linearization of adsorption isotherms revealed that the Langmuir model is best adapted to describe the observed occurrence, indicating a good distribution of active sites over the adsorbent surface.
