Synthesis of MOFs for RhB Adsorption from Wastewater

Abstract

Fe-MOFs were prepared using a solvothermal method, and were characterized by scanning electron microscopy. We explored the application of Fe-MOFs as an adsorbing material for the removal of Rhodamine B (RhB) from aqueous solutions. The experimental data were simulated by dynamics and the results showed that the pseudo–second-order kinetics model was appropriate for analysis of RhB removal. We studied the adsorption capacity of MOF materials under different masses, concentrations, and pH conditions. When the pH was 6, the maximum adsorption capacity within 4 h was 135 mg/g. In summation, the removal of RhB from wastewater using MOFs is feasible, inexpensive, and effective. Hence, our findings indicate that MOFs have a broad application in the purification of wastewater.

“…The second stage was from 384 to 668°C, where a sharp loss occurred between 494 and 668 °C. In this stage, the organic ligands of Cu/Co‐MOF were mainly lost, leading to a collapse of the structure with a loss of 30% 48 . Further, 56% of the solid remained at a temperature up to 800°C, illustrating that the molecule was stable at a temperature below 384°C and hence the structure was not destroyed.…”
