“…For example, Ahmad et al [ 33 ] prepared activated carbon from durian seeds and studied the removal of MG; Akar et al [ 34 ] tried to use tea leaves to eliminate MG from water; Basirun et al [ 35 ] prepared activated carbon from the banana stalk as a lignocellulosic agricultural waste. MG has also been removed from an aqueous solution using ceramic clays as adsorbents [ 36 ].…”

Almond shell-based biocarbon is a cheap adsorbent for the removal of malachite green, which has been investigated in this work. FT-IR, DRX, and BET were used to characterize almond shell-based biocarbon. The nitrogen adsorption-desorption isotherms analysis results showed a surface area of 120.21 m2/g and a type H4 adsorption isotherm. The parameters of initial dye concentration (5–600 mg.L−1), adsorbent mass (0.1–0.6 mg), and temperature (298–373 K) of adsorption were investigated. The experiments showed that the almond shell could be used in a wide concentration and temperature range. The adsorption study was fitted to the Langmuir isotherm and the pseudo-second-order kinetic model. The results of the FT-IR analysis demonstrated strong agreement with the pseudo-second-order chemisorption process description. The maximum adsorption capacity was calculated from the Langmuir isotherm and evaluated to be 166.66 mg.g−1. The positive ∆H (12.19 J.mol−1) indicates that the adsorption process is endothermic. Almond shell was found to be a stable adsorbent. Three different statistical design sets of experiments were taken out to determine the best conditions for the batch adsorption process. The optimal conditions for MG uptake were found to be adsorbent mass (m = 0.1 g), initial dye concentration (C0 = 600 mg.L−1), and temperature (T = 25 °C). The analysis using the D-optimal design showed that the model obtained was important and significant, with an R2 of 0.998.

In this article, the effectiveness of two different application methods (photocatalytic degradation and adsorption) onto the created solid nanomaterials for the removal of malachite green (MG) was investigated. Copper ferrite nanoparticles (CF) and copper ferrite/calcium alginate composite (CG) were synthesized as two studied solid samples. By using XRD, TGA, FTIR, DRS, nitrogen adsorption/desorption isotherm, pHPZC, SEM, and TEM, the physicochemical and morphological properties of the solid samples were tested. Sample dose, pH, initial MG concentration, shaking time, ionic strength, UV light power, and temperature were the key experimental parameters that were established. The obtained results demonstrated that at 40 °C, CG reached a greater adsorption capacity (297.62 mg/g). The spontaneous, endothermic, and advantageous adsorption process of MG was proved by the best fitting of pseudo-second order, Elovich, intra-particle diffusion, Langmuir, Dubinin-Radushkevich, and Temkin models onto all the produced materials. The maximum percentage of MG degradation by CG (89.9%) was accomplished by utilizing 1.0 g/L of catalyst mass, an initial MG concentration of 10 mg/L, and 33 W. Arrhenius and Eyring–Polanyi models well applied the MG photodegradation onto the catalyst surface.
