Recent Advances in Adsorption Kinetic Models: Their Application to Dye Types

Arabian Journal of Chemistry, Journal Year: 2021, Volume and Issue: 14(4), P. 103031 - 103031

Published: Feb. 3, 2021

The increased environmental awareness and tighter regulatory standards have prompted various industries to seek appropriate wastewater treatment technologies, in particular, for colored wastewater. This review provides detailed information on dyes, their classification, the impact of water pollution national (Morocco) international scales. Recent studies about adsorption process removal dyes from aqueous solution with different adsorbents recognized as a sustainable terms minimization, recovery, reuse were evaluated. It is also aimed synthesize current literature data concerning low-cost by systematically highlighting both characteristics capacities. Moreover, applicability kinetic isothermal models wide range reported addition regarding continuous system adsorption.

The primary, most obvious parameter indicating water quality is the color of water. Not only can it be aesthetically disturbing, but also an indicator contamination. Clean, high-quality a valuable, essential asset. Of available technologies for removing dyes, adsorption used method due to its ease use, cost-effectiveness, and high efficiency. process influenced by several parameters, which are basis all laboratories researching optimum conditions. main objective this review provide up-to-date information on studied influencing factors. effects initial dye concentration, pH, adsorbent dosage, particle size temperature illustrated through examples from last five years (2017-2021) research. Moreover, general trends drawn based these findings. removal time ranged 5 min 36 h (E = 100% was achieved within 5-60 min). In addition, nearly 80% efficiency with just 0.05 g adsorbent. It important reduce (with Φ decrease E 8-99%). Among dyes analyzed in paper, Methylene Blue, Congo Red, Malachite Green, Crystal Violet were frequently studied. Our conclusions previously published literature.

Novel approach for effective removal of methylene blue dye from water using fava bean peel waste

Scientific Reports, Journal Year: 2020, Volume and Issue: 10(1)

Published: May 8, 2020

Abstract Fava bean peels, Vicia faba (FBP) are investigated as biosorbents for the removal of Methylene Blue (MB) dye from aqueous solutions through a novel and efficient sorption process utilizing ultrasonic-assisted (US) shaking. Ultrasonication remarkably enhanced rate relative to conventional (CV) shaking, while maintaining same capacity. Ultrasonic amounted four times higher than its counterpart at 3.6 mg/L initial concentration, 5 g/L adsorbent dose, pH 5.8. Under dose conditions, percent ranged between 70–80% low concentration range (3.6–25 mg/L) reached about 90% 50 concentration. According Langmuir model, maximum capacity was estimated be 140 mg/g. A multiple linear regression statistical model revealed that adsorption significantly affected by time. FBP could successfully utilized low-cost biosorbent MB wastewater via US biosorption an alternative CV sorption. yields capacities biosorption, but with significant reduction in operational times.
