Removal of Purpurin From Aqueous Samples By Fe3O4Magnetic Nanoparticles

The nanoparticles of Fe3O4 were used for the removal of purpurin dye from aqueous solutions. Adsorption study was performed under different experimental conditions. The adsorption of purpurin onto Fe3O4 nanoparticles was affected by the initial pH, dye concentration, adsorbent amount, contact time and temperature. The maximum adsorption capacity of Fe3O4 were measured. The isotherm modelsof Langmuir and Freundlich were used to fit the experimental adsorption equilibrium data of purpurin on Fe3O4 adsorbents. The enthalpy change (ΔH0) and entropy change (ΔS0) was 24.3 kJ mol−1 and 95.5 J mol−1K−1, respectively
