    Recent advances in adsorption kinetic models: their application to dye types
    (Elsevier B.V., 2021) Benjelloun, Mohammed; Miyah, Youssef; Akdemir Evrendilek, Gülsün; Zerrouq, Farid; Lairini, Sanae
    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 environmental impact of water pollution on the national (Morocco) and international scales. Recent studies about the adsorption treatment process for the removal of dyes from the aqueous solution with different adsorbents recognized as a sustainable solution in terms of minimization, recovery, and reuse were evaluated. It is also aimed to synthesize the current literature data concerning low-cost adsorbents by systematically highlighting both their characteristics and capacities. Moreover, the applicability of various kinetic adsorption and isothermal models to the removal of dyes by a wide range of adsorbents is reported in addition to information regarding continuous system adsorption.

    Synergistic effect of coupling ozonation/adsorption system for toxic dye efficient removal: chemometric optimization by Box-Behnken response surface methodology
    (Desalination Publ, 2023) Benjelloun, Mohammed; Miyah, Youssef; Evrendilek, Gulsun Akdemir; Lalami, Abdelhakim El Ouali; Demir, Irem; Atmaca, Bahar; Ssouni, Salma
    This work aims to optimize the ozonation/adsorption coupling system as an advanced technique for the removal of the dye crystal violet (CV) in the presence of new innovative material based on the Capparis spinosa L waste (CSLW). Data from operational parameters such as adsorbent dose (X1), CV concentration (X2), and oxygen flow rate (X3) were used to optimize the dye removal rate (Y) by the Box-Behnken design (BBD) response surface methodology. Under the ideal conditions of X1 (2 g center dot L-1), X2 (100 mg center dot L-1), and X3 (4 L center dot min-1), the rate Y exceeded 99.75%. The complete removal of the CV dye by the ozonation/adsorption coupling results from the selective interactions between the surface groups of the CSLW material, the ozone, and the various charges present in the solution. The coupling mechanism indicates that ozonation partially degrades the CV dye and the adsorption process significantly increases the percentage of removal due to the different adsorbent-adsorbate interactions. Due to the low power consumption of the oxygenator and ozonator and the lack of CSLW cost, the treatment of CV by the ozonation/adsorption coupling could cost about $1.8518 L-1. Thus, this process could be generalized through an industrial pilot-scale application.
