Heavy metal removal from wastewater and valuable recovery electronic waste are of critical environmental economic significance. Separation based on the use polymer inclusion membranes (PIMs) with advantage simultaneous extraction stripping has emerged as a promising approach for efficient selective ion and/or wastewaters or waste. However, conventional extractants used in PIMs often not to certain ions, highly volatile toxic, leading low efficiency significant concerns. Ionic liquids (ILs) have negligible vapor pressure can be purposely designed specific ions. In addition, ILs multifunctional by purpose design, instance, having functions both plasticizers. Therefore, marriage (i.e., IL-based PIMs) been attractive various this review, we discuss fundamentals PIMs, explore key considerations provide an overview different applications. By leveraging advantages ILs, offers new possibilities sustainable recovery. This review state-of-the-art assessment previous efforts strategies well future research directions ions through application ILs-based PIMs.

Standardized methodology for performance evaluation in using polyaniline-based adsorbents to remove aqueous contaminants

Journal of environmental chemical engineering, Год журнала: 2024, Номер 12(3), С. 112650 - 112650

Опубликована: Март 30, 2024

In literature, mistakes and inconsistencies in evaluation of the adsorption equilibrium, kinetics, thermodynamics pollutants removal often exist. Here, we review these propose a standardized methodology, with focus on polyaniline (PANI)-based adsorbents to correctly determine equilibrium data, kinetic rates, time, capacity. Removal aqueous by PANI-based through well-designed experiments predominantly involves monolayer chemisorption. The nature adsorption, whether heterogeneous or homogeneous, is contingent upon morphological characteristics distribution functional groups adsorbents. literature reflects multitude complexities implementation subsequent analysis results. Researchers have attempted address complexities, yet variations findings remain due diverse experimental conditions applied. This study critically examines existing methodologies their develop distinctive approach for rational design, meticulous sampling, accurate calculations. Controversial descriptions regarding kinetics are scrutinized scientifically reasonable presented. Finally, main steps determining mechanisms via physiochemical studies recommended. contributes insightful perspectives field offering more robust methodology conduct interpret results, thereby enhancing reliability comparability adsorption.

Activated Carbon Prepared from Waste Coffee Grounds: Characterization and Adsorption Properties of Dyes

Materials, Год журнала: 2024, Номер 17(13), С. 3078 - 3078

Spent coffee grounds (SCGs) have great potential as a useful, value-added biological material. In this context, activated carbon (AC) was prepared from SCGs by an activation process using H3PO4 at 600 °C in the air and used adsorbent for azo dye AO7, model molecule colorants found textile industry effluents. X-ray diffraction, SEM BET revealed that AC predominantly amorphous, consisting of powder 20–100 µm particles with mesopores averaging 5.5 nm pore size. Adsorption kinetics followed pseudo-second-order law, while Langmuir best fitted experimental isotherm data (maximum capacity 119.5 mg AO7 per g). The thermodynamic parameters adsorption endothermic spontaneous. All characterizations indicated occurred physisorption via mainly π–π interactions. removal efficiency optimized means Box–Behnken design response surface methodology 98% initial concentration 20 mg·L−1 pH 7.5 dose 0.285 g·L−1 contact time 40 min. These results clearly show can be useful material efficiently removing organic matter aqueous solutions.
