Abstract

The research successfully synthesized a composite MIL-100(Fe) modified Fe3O4 (Fe3O4@MIL-100(Fe)) catalyst and examined its efficiency in degrading methyl orange (MO) through the photo-Fenton process compared to Fenton. The different percentages of Fe3O4 were integrated into MIL-100(Fe) and their effects on material characteristics and degradation capabilities were studied. Ex-situ synthesis involved varying Fe3O4 weight ratios (3, 10, and 20% w/w). Characterization techniques confirmed the integration of Fe3O4 and MIL-100(Fe) and revealed changes in surface area, pore size, and thermal stability with Fe3O4 addition. Meanwhile, removal tests showed promising results with the photo-Fenton process exhibiting maximum efficiency (95.51%) using 10% Fe3O4@MIL-100(Fe). This study provides valuable insights into developing efficient photo-Fenton catalysts for environmental remediation, particularly for addressing dye pollution in wastewater by highlighting the potential of Fe3O4@MIL-100(Fe) composites in this context.

Abstract

It is generally known that zeolite has potential for heavy metal adsorption. The objectives of this study were to synthesize and characterize zeolite ZSM-5 and to figure out the adsorption capacity of zeolite ZSM-5 for heavy metals of Cu2+, Pb2+ and Cd2+. Characterization of zeolite ZSM-5 included some variables i.e. crystal structure (XRD), morphology (SEM), specific surface area and total pore volume (N2 physisorption). Adsorption capacity of zeolite ZSM-5 was analysed using a batch system with heavy metals of Cu2+, Pb2+ and Cd2+ in various concentrations (50, 100, 150, 200 and 250 ppm) with contact times 30, 60, 90, 120 and 250 minutes. Adsorption data was calculated by Langmuir and Freundlich isotherm. The results showed that the maximum adsorption capacity of zeolite ZSM-5 against heavy metals of Pb2+, Cu2+, and Cd2+, were 74.07, 69.93 and 60.24 mg g-1, respectively. These indicated that synthetic zeolite ZSM-5 had potential to adsorb heavy metals. The results also suggested that the adsorption capacity was affected by the pore size of zeolite, negative charge of zeolite, diameter of hydrated and electronegative ion.
