Leather and textile industrial effluents are the main disseminating routes for chromium contamination of water bodies, causing adverse impacts on public environmental health. The attempt to remediate through conventional wastewater treatment methods is inefficient. Therefore, this study aims synthesize zinc-doped nickel ferrite pinecone biochar (Zn-NiF@PBC) nanocomposite removal from systems. Zn-NiF@PBC was synthesized via co-precipitation method. properties (Zn-NiF) were effectively modified by blending with at 1, 5, 10, 15 % (w/w) which successfully embedded Zn-Ni nanoparticles. This characterized confirmed typical adsorbent such as a high surface area 104 m2/g, conducive pore volume 0.117 cm3/g size 3.41 nm (BET), interactive multi-functional groups (FTIR), charge determination (pHpzc,), crystalline structure (XRD) very rough morphology (SEM). maximum adsorption found be 95 specific experimental condition pH 3, dose 1 g/50 mL, contact time 120 min, initial concentration 100 mg/L. data best fitted Langmuir isotherm R2 0.98 indicating process homogeneous monolayer whereas kinetics resembling second-order kinetic 0.99. Moreover, thermodynamics spontaneous, endothermic, increased change in entropy. Finally, regeneration effective up five 5 cycles but gradually degrading terms efficiency after 3 cycles. In general, can huge potential scale-up extend other pollutants clear-up.

Advancements in adsorption and photodegradation technologies for Rhodamine B dye wastewater treatment: fundamentals, applications, and future directions

Green Chemical Engineering, Год журнала: 2023, Номер 5(4), С. 440 - 460

Опубликована: Дек. 30, 2023

Organic dye pollutants present in wastewater pose a significant global challenge. Among pollutants, the synthetic Rhodamine B (RB) stands out due to its non-biodegradable nature and associated neurotoxic, carcinogenic, respiratory irritant properties. Extensive research has been conducted on efficacy of adsorption photodegradation techniques for removal RB from wastewater. While advanced oxidation processes (AOPs) have gained considerable attention their effectiveness recent years, underlying behaviors mechanisms these technologies remain incompletely understood. Therefore, comprehensive summary progress this domain is imperative clarify basics up-to-date achievements. This review provides an in-depth exploration fundamentals, advancements, future trajectories treatment technologies, mainly encompassing photodegradation. work starts with general introduction outlining sources, toxicity, diverse applicable strategies. Subsequently, it thoroughly examines crucial within non-photochemical, photochemical, such as UV light-assisted AOP, catalyst-assisted ozonation, Fenton systems, electrochemical technology. The primary objective furnish broad overview techniques, elucidating effectiveness, limitations, applicability. Following this, encapsulates state-of-the-art computational simulations pertaining interactions clays other adsorbents. Lastly, delves into column dye, elucidates various influencing factors, including bed height, feed concentration, pollutant feeding or flow rate, regeneration. panoramic aims provide valuable insights suitable gaps, applicability containing dye.
