Synthesis of zeolite from industrial wastes: a review on characterization and heavy metal and dye removal

Environmental Science and Pollution Research, Journal Year: 2024, Volume and Issue: 31(29), P. 41791 - 41823

Published: June 11, 2024

Abstract Increasing world population, urbanization, and industrialization have led to an increase in demand production consumption, resulting industrial solid wastes pollutant levels water. These two main consequences become global problems. The high Si Al content of suggests that they can be used as raw materials for the synthesis zeolites. In this context, when literature studies conducted obtain synthetic zeolites are evaluated, it is seen hydrothermal method generally used. order improve performance terms energy cost, time, even product quality, additional methods such alkaline fusion, ultrasonic effect, microwave support been developed. synthesized by different techniques exhibit superior properties surface area well-defined pore sizes, thermal stability, cation exchange capacity, regeneration ability, catalytic activity. Due these specific properties, recognized one most effective removal pollutants. toxic heavy metals dyes water their carcinogenic effects long-term exposure pose a serious risk living organisms. Therefore, should treated at specified before discharge environment. review study, processes including developed from were evaluated. Studies using health environmental risks reviewed. addition, EPMA, SEM, EDX, FTIR, BET, AFM, 29 27 NMR techniques, which characterization zeolites, presented thermodynamics adsorption, effect temperature, pH investigated. It expected consumption reduced large-scale applications alternative zeolite introduction into industry. envisaged utilizing will obtaining green technology. use wide variety applications, especially problems, holds great promise.

Adsorption of Cu(II) and Ni(II) from Aqueous Solutions Using Synthesized Alkali-Activated Foamed Zeolite Adsorbent: Isotherm, Kinetic, and Regeneration Study

Molecules, Journal Year: 2024, Volume and Issue: 29(10), P. 2357 - 2357

Published: May 16, 2024

Water pollution, particularly from heavy metals, poses a significant threat to global health, necessitating efficient and environmentally friendly removal methods. This study introduces novel zeolite-based adsorbents, specifically alkali-activated foamed zeolite (AAFZ), for the effective adsorption of Cu(II) Ni(II) ions aqueous solutions. The adsorbents’ capabilities were comprehensively characterized through kinetic isotherm analyses. Alkaline activation induced changes in chemical composition crystalline structure, as observed via XRF XRD AAFZ exhibited significantly larger pore volume (1.29 times), higher Si/Al ratio (1.15 lower crystallinity compared ZZ50, thus demonstrating substantially capacity ZZ50. maximum monolayer capacities ZZ50 determined be 69.28 mg/g 99.54 mg/g, respectively. In case Ni(II), at 48.53 88.99 For both optimum pH was found 5 6, Equilibrium reached around 120 min, pseudo-second-order kinetics accurately depicted chemisorption process. Langmuir model effectively described adsorbents. Furthermore, regeneration experiment demonstrated that could regenerated minimum two cycles using hydrochloric acid (HCl). These findings highlight potential developed adsorbents promising tools practical applications.
