“…Despite its high demand in several sectors and elds such as the textile industry, aquaculture and hatchery industry, the use of malachite green (MG) and other dyes (MB and RhB) is not recommended because they have carcinogenic and mutagenic effects on human health. [94][95][96] To date, many reports have been published on the removal of malachite green from aqueous media using ZIF-8-based materials. For example, Zhao et al 73 assembled ZIF-8s on g-C 3 N 4 /Fe 3 O 4 to produce ZIF-8/g-C 3 N 4 /Fe 3 O 4 nanocomposites, which were effective for adsorbing varying concentrations of malachite green.…”

“…It can be seen that the percentage removal of MG increases sharply and then reaches an almost constant value when the adsorbent dose increases from 0.04 to 0.14 g. This is because there are more binding sites of the adsorbent and a larger adsorption surface. When the dose was increased from 0.40 g to 1.4 g, no significant improvement in MG removal percentage was observed; therefore, the adsorbent dose of 0.1 g was identified as the preferred amount of adsorbent for further research [17,18].…”

This work explored the adsorption of Malachite Green (MG) dye by Acorn Pericarp (AP) in the context of biomass valorization. The Acorn Pericarp was analyzed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction. The adsorption capacity under optimal experimental conditions was studied at different adsorbent doses, the initial concentration times of the dye and pH. The results presented in this work on the adsorption kinetics of MG showed that the pseudo-first-order model (R2 = 0.9971) better described the adsorption kinetics at 10−5 M. The experimental isotherms showed that Acorn Pericarp adsorption followed the Langmuir isotherm model (R2 = 0.9889). The thermodynamic study showed that MG adsorption is endothermic (ΔH° > 0) and spontaneous (ΔG° < 0). For a sustainable industry, the sludge was converted into reinforcement of polystyrene using in-situ polymerization with 10% by weight of filler. A morphological and structural analysis was performed using SEM and FTIR, the results of characterization showed that the AP sludge was incorporated well into the PS matrix.

A laboratory-synthesized triblock copolymer poly(ethylene oxide-b-acrylic acid-b-styrene) (PEG-PAA-PS) was used as a template to synthesize hollow BaCO3 nanoparticles (BC-NPs). The triblock copolymer was synthesized using reversible addition–fragmentation chain transfer radical polymerization. The triblock copolymer has a molecular weight of 1.88 × 104 g/mol. Transmission electron microscopy measurements confirm the formation of spherical micelles with a PEG corona, PAA shell, and PS core in an aqueous solution. Furthermore, the dynamic light scattering experiment revealed the electrostatic interaction of Ba2+ ions with an anionic poly(acrylic acid) block of the micelles. The controlled precipitation of BaCO3 around spherical polymeric micelles followed by calcination allows for the synthesis of hollow BC-NPs with cavity diameters of 15 nm and a shell thickness of 5 nm. The encapsulation and release of methotrexate from hollow BC-NPs at pH 7.4 was studied. The cell viability experiments indicate the possibility of BC-NPs maintaining biocompatibility for a prolonged time.
