Modified Irvingia gabonensis nut waste (MIg) was used for malachite green (MG) removal from aqueous solution. Adsorption operational parameters such as pH, adsorbent load, concentration with contact time were investigated to establish the behavior of MIg for subsequent applications in a complex media. The potency of MIg in the effective treatment of binary and ternary mixture of MG/rhodamine B (RhB) dyes and MG/RhB/Cu 2+ solution was also studied. Optimum MG adsorption was obtained at pH of 6.0. MG-MIg kinetics adsorption data was best described by the Pseudo second order kinetic model. MG adsorption onto MIg was predominantly onto a uniform site and the maximum monolayer adsorption capacity was obtained to be 250mg/g. MG and RhB synergistically aided the removal of each other both in binary and ternary solutions hence 99.99% removal was observed for the two dyes after treatment with MIg. Cu 2+ showed no change in concentration after treatment with MIg.

“…The adsorption method for wastewater treatment has the advantages of inexpensiveness, high efficiency, easy operating procedures, system flexibility, wide-range applicability, insensitivity to pollutants, and facilitation of material recovery [ 5 , 6 ]. Various low-cost, environmentally friendly alternative adsorbents have been prepared from agricultural waste or byproducts for the removal of dyes from wastewater, such as mung bean husk [ 7 ], corn stalk [ 8 ], rice bran [ 9 ], bamboo [ 10 ], rice husk [ 11 ], and Artocarpus odoratissimus leaves [ 12 ]. These green adsorbents have the major characteristic properties of low cost with satisfactory adsorption capacities and environmentally friendly nature (such as derived from abundant natural sources, biodegradable, non-toxic, etc.…”

Hydrogel beads based on the husk of agarwood fruit (HAF)/sodium alginate (SA), and based on the HAF/chitosan (CS) were developed for the removal of the dyes, crystal violet (CV) and reactive blue 4 (RB4), in aqueous solutions, respectively. The effects of the initial pH (2–10) of the dye solution, the adsorbent dosage (0.5–3.5 g/L), and contact time (0–540 min) were investigated in a batch system. The dynamic adsorption behavior of CV and RB4 can be represented well by the pseudo-second-order model and pseudo-first-order model, respectively. In addition, the adsorption isotherm data can be explained by the Langmuir isotherm model. Both hydrogel beads have acceptable adsorption selectivity and reusability for the study of selective adsorption and regeneration. Based on the effectiveness, selectivity, and reusability of these hydrogel beads, they can be treated as potential adsorbents for the removal of dyes in aqueous solutions.

“…In recent years, many technologies have been widely used to remove toxic dyes from wastewater, such as adsorption (Zaidi et al 2019), photocatalytic degradation (Khatarr & Kasiri 2010;Mangindaan et al 2020), coagulation (Dizge et al 2008), solvent extraction (Nidheesh & Gandhimathi 2012), and membrane filtration (Rashidi et al 2015;Febrianto et al 2019;Gunawan et al 2019). Among these technologies, adsorption has been popularly applied in many countries due to its low production cost, easy operation, and sustainability (Ngulube et al 2017).…”

In this study, spent Auricularia auricula substrate (AS)-derived biochar (ASBCs) and activated biochar with NaOH (A-ASBC) were evaluated for the adsorption of cationic azo dyes, including methylene blue (MB), rhodamine B (RB), and crystal violet (CV), from single and binary adsorptive systems. A-ASBC showed a higher maximum adsorption capacity for these dyes (MB: 53.62 mg·g−1, RB: 32.33 mg·g−1, CV: 735.73 mg·g−1) than ASBCs in a single system because it had a greater specific surface area and more oxygen containing-functional groups on the surface. The adsorption process of the three dyes onto the adsorbents was in good agreement with the Freundlich adsorption isotherm and fit the pseudo-second-order kinetic model, which revealed sorbate polymolecular layer formation over the adsorbent surface and the involvement of chemisorption. The adsorption mechanism showed that the adsorption of three dyes on adsorbents could be postulated as a multistep process with extraordinary affinity-induced adsorption in terms of both physisorption and chemisorption. In the binary adsorptive system, the results showed that all MB, RB, and CV had antagonistic/competitive effects on each other's adsorption (QBinary/QSingle < 1). Furthermore, a phytotoxic assay affirmed the effectiveness of the adsorbent in adsorbing dye species from aqueous solutions using Brassica pekinensis L. seeds as the model. Therefore, activated biochar prepared from AS can be used as a potentially economical and effective adsorbent for treating printing and dyeing wastewater.
