Toxics, Год журнала: 2024, Номер 12(9), С. 652 - 652

Опубликована: Сен. 5, 2024

Based on the life cycle assessment methodology, this study systematically analyzes energy utilization of environmental waste through photocatalytic treatment and simultaneous hydrogen production. Using 10,000 tons organic wastewater as functional unit, evaluates material consumption, utilization, impact potential synchronous production system (specifically, process 4-NP with CDs/CdS/CNU). The findings indicate that impacts from photochemical primarily manifest in freshwater ecological toxicity, marine terrestrial non-carcinogenic toxicity to humans. These stem catalyst's adsorption metal leaching during photo-degradation processes waste. By implementing reasonable modifications morphological refinements catalyst, these effects can be mitigated while achieving enhanced efficiency processing research outcomes provide valuable insights for advancing sustainable development green technology utilization.

Influence of Arsenate Competition on Tungstate Sorption by Soil

Sustainability, Год журнала: 2024, Номер 16(21), С. 9363 - 9363

Опубликована: Окт. 28, 2024

The green and digital transitions toward sustainable development will drive an increased demand for critical raw materials, among which tungsten plays a crucial role in emerging technologies. Understanding the sorption processes of soils is essential assessing its bioavailability potential toxicity to living organisms. In many soils, may co-exist with other contaminants, such as arsenic. Investigating competitive between these two anions helps clarify how they interact within soil matrix. Batch experiments were conducted on three Mediterranean evaluate behavior tungstate arsenate, both individually combination, using “Langmuir-type” model. Both exhibited highest acidic lowest alkaline soils. While shapes isotherms similar single binary systems, maximum values decreased when co-occurring anion was present. These reductions can be attributed competition sites, have high affinity anions. all tested percentage decrease arsenate presence greater than observed arsenate. Gaining deeper understanding tungsten’s mechanisms critical, not only advancing environmental research but also informing regulations that currently give limited attention

Zinc Oxide/Moringa Oleifera Gum-Grafted L-Methionine-Functionalized Polyaniline Bionanocomposites for Water Purification

Water, Год журнала: 2024, Номер 16(18), С. 2576 - 2576

Опубликована: Сен. 11, 2024

This study evaluates the preparation of novel ternary functional adsorbents based on polyaniline, zinc oxide nanoparticles, and moringa oleifera gum to produce oxide/Moringa gum-grafted L-methionine-functionalized polyaniline bionanocomposites (ZM-g-Pani) employed sequestrate divalent metal ions (Cd2+, Hg2+ Pb2+) from wastewater samples. The morphological structural properties ZM-g-Pani were exploited using FT-IR, FE-SEM/EDS, TEM, XRD. FT-IR FE-SEM studies show that as prepared nanocomposite has an abundant number reactive groups a porous structure, thus demonstrating outstanding cation removal. confirms attachment L-methionine is facilitated by C-S linkage. Both TEM techniques confirmed clustered granules ZnO over surface which ultimately provided more area adsorb ions. demonstrated Cd2+, Pb2+ could undergo physical sorption chemisorption simultaneously during adsorption process. maximum capacity was 840.33, 497.51, 497.51 mg/g for Hg2+, Pb2+, respectively. impact co-existing ions, including NO3−, PO43−, SO42−, Cl−, Na+, Cu2+, Al3+, showed there no notable alterations in selected with ZM-g-Pani. eight successive regeneration cycles than 85% removal efficiency.

Effective removal of As5+ from aqueous medium using date palm fiber biochar/chitosan/glutamine nanocomposite: kinetic and thermodynamic studies

Research Square (Research Square), Год журнала: 2024, Номер unknown

In the current work, three adsorbent materials were developed; biochar derived from date palm fiber (C), biochar/chitosan nanoparticles (CCS), and composite supplemented with glutamine (CCSG). These compounds used as solid adsorbents to remove As⁵⁺ polluted water. Several characterization approaches investigate all synthesized adsorbents, including TGA, N₂ adsorption/desorption isotherm, SEM, TEM, ATR-FTIR, zeta potential. CCSG demonstrated good thermal stability, a maximum specific surface area of 518.69 m²/g, microporous radius 0.97 nm, total pore volume 0.25 cm³/g, an average particle size 38 pH_pzc 6.9. To optimize reaction conditions, various sorption factors examined, contact time, pH, initial concentration, dosage, temperature, ionic strength. The study found that modified samples able more (CCS; 256.0 mg/g CCSG; 376.0 mg/g) than unmodified ones (C; 150.5 mg/g). removal procedure corresponded well Langmuir isotherm model. Thermodynamic kinetic experiments show Elovich, PFO, Van't Hoff plot endothermic, spontaneous, physisorption nature are best fitted models. EDTA has highest desorption efficiency percentage (98.8%). enhanced reusability after six application cycles adsorption/desorption, only 4% decrease in adsorption. This demonstrates effectively wastewater use agricultural waste residues (date fiber; DPF) for environmental remediation purposes.
