A Sustainable Development Strategy for Municipal Solid Waste Incineration Bottom Ash: Adsorption Performance and Mechanism in Removing Heavy Metals from Water

Sustainability, Journal Year: 2025, Volume and Issue: 17(8), P. 3466 - 3466

Published: April 13, 2025

As urbanization progresses rapidly, the pollution of heavy metal wastewater and disposal municipal solid waste incineration bottom ash (MSWI-BA) have emerged as significant challenges. MSWI-BA is a porous material recognized an environmentally friendly adsorbent. To prevent escalating costs in future practical engineering applications, this study employed unmodified, natural MSWI-BA. This research assessed adsorption capabilities for Pb(II) Zn(II) through static experiments, which included kinetics isotherm studies. The influence various factors on performance was investigated adjusting solution pH amount ash, competitive conditions, regeneration experiments. Advanced techniques, including ESEM-EDS, XRD, FTIR, were utilized to analyze mechanisms. results indicated that under conditions values 4 5, temperature 318 K, dosage 0.1 g/20 mL, maximum capacities 89.09 mg/g 33.77 mg/g, respectively. demonstrates robust potential over multiple cycles, validating its feasibility. principal mechanisms removal include chemical precipitation, ion exchange, surface complexation. By repurposing it efficient low-cost adsorbent, represents sustainable strategy.

Simultaneous Catalytic Oxidation of Benzene and Toluene over Pd-CeZrOx Catalysts

Atmosphere, Journal Year: 2024, Volume and Issue: 15(11), P. 1301 - 1301

Published: Oct. 29, 2024

Since actual industrial emissions contain a wide range of volatile organic compounds, studies into the simultaneous catalytic degradation multi-component VOCs are essential. This work developed Pd-CeZrOx samples for elimination benzene and toluene. Firstly, CeZrOx supports were synthesized using several methods (co-precipitation, CTAB template co-precipitation, sol–gel method). Pd active species then added 1.0Pd-CeZrOx impregnation procedure. XRD, BET, NH3-TPD, Raman, EPR, XPS, H2-TPR utilized to analyze as-prepared samples. The performance tests reveal that 1.0Pd-CeZrOx-CTAB outperforms 1.0Pd-CeZrOx-PM 1.0Pd-CeZrOx-CASG, displays superior activity both toluene oxidation. improved redox properties, abundant surface oxygen vacancies, Pd2+ sample may be responsible
