Abstract
This research investigated the synthesis of Ag-doped Fe (Ag-Fe@BC) using plant biochar (PLC) for the degradation of Myclobutanil (MBL) pesticide. Various analytical techniques, including Fourier-transform infrared (FTIR), X-ray diffraction (XRD), scanning electron such as SEM, energy dispersed x-ray, (EDX), Brunauer–Emmet–Teller (BET) and thermogravimetric analysis (TGA), confirmed the successful synthesis of Ag-Fe@BC in both highly crystalline and amorphous forms. Wastewater containing MBL was treated with Ag-Fe@BC, and the result demonstrated a 76% removal of MBL within a 140-time interval. The mechanistic degradation of MBL through OH radicals under light was comprehensively evaluated. Hydrogen peroxide (H2O2) was employed in conjunction with the doping material (Ag-Fe@BC) under solar light to enhance the degradation of MBL. The study investigated various parameters, including concentration, temperature, pH, co-existing substances, and the presence of natural organic matter, to understand their effects on MBL degradation. Detailed toxicity analyses of MBL and its degradation products (DPs) revealed the formation of non-toxic acetate, demonstrating the treatment technology’s enhanced capability in reducing toxicity.
期刊介绍:
The journal includes papers in the following areas:
– Simple organic liquids and mixtures
– Ionic liquids
– Surfactant solutions (including micelles and vesicles) and liquid interfaces
– Colloidal solutions and nanoparticles
– Thermotropic and lyotropic liquid crystals
– Ferrofluids
– Water, aqueous solutions and other hydrogen-bonded liquids
– Lubricants, polymer solutions and melts
– Molten metals and salts
– Phase transitions and critical phenomena in liquids and confined fluids
– Self assembly in complex liquids.– Biomolecules in solution
The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include:
– Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.)
– Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.)
– Light scattering (Rayleigh, Brillouin, PCS, etc.)
– Dielectric relaxation
– X-ray and neutron scattering and diffraction.
Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
