“…To assess the performance of Fe3O4@GT@Mg NPs for the adsorption of MB removal, a comparison was made with other adsorbents that have been reported for the same purpose, including biomass matrix adsorbents, magnetic nanocomposite adsorbents, and biomass-based magnetic nanocomposite adsorbents (Table S4) [37][38][39][40][41][42][43][44]. The results illustrated the Fe3O4@GT@Mg NPs' high removal rate and adsorption capacity, which were generated throughout the current testing.…”

In this study, a novel green tea/Mg-functionalized magnetic nano-adsorbent, denoted as GTE-MgO-Fe3O4 NPs, was developed and applied to the extraction of Methylene Blue (MB) from water-based solutions. The GTE-MgO-Fe3O4 NPs were synthesized by incorporating green tea extracts (GTE) and Mg species onto the surface of Fe3O4 nanoparticles using a hydrothermal method. Characterization analyses corroborated the successful functionalization of the Fe3O4 surface with GTE and Mg species, resulting in a superparamagnetic adsorbent equipped with abundant surface functional groups, which promoted MB adsorption and facilitated magnetic separation. Batch experiments revealed that different operating parameters had an impact on the adsorption behavior, such as adsorbent dosage, pH, coexisting ions, contact time, the initial MB concentration, and temperature. The investigations of adsorption kinetics and isotherms emphasized that the MB adsorption onto GTE-MgO-Fe3O4 NPs was an exothermic process dominated by chemisorption. The experimental adsorption capacity of GTE-MgO-Fe3O4 NPs for MB surpassed 174.93 mg g−1, markedly superior to the performance of numerous other adsorbents. Ultimately, the utilized GTE-MgO-Fe3O4 NPs could be effectively regenerated through acid pickling, retaining over 76% of its original adsorption capacity after six adsorption–desorption cycles, which suggested that GTE-MgO-Fe3O4 NPs was a suitable adsorbent for eliminating MB from effluent.

“…Based on Fig. 3, MRC shows sharp peaks compared to RC at 2θ 35.46, 43.04, 57.22, and 62.58° [31]. The asymmetrical RC peaks turn into sharp peaks in the XRD MRC pattern, indicating that RC has been coated with magnetite so that the peaks appear with sharp intensity.…”

Rubber fruit shells-derived carbon (RC) modified with magnetite (MRC) and triethoxyphenylsilane (TEPS) (SRC) made from rubber fruit shells were used to adsorb crystal violet (CV) dye effectively. The RC was successfully modified by magnetite and TEPS, according to the characterization of the adsorbent utilizing Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy-energy-dispersive X-ray (SEM-EDX) showed that the RC was successfully modified by magnetite and TEPS. Several adsorption process parameters were investigated, and the ideal results were obtained with an adsorbent dose of 0.1 g, pH 10, contact time of 15 min, and initial concentration of CV 250 mg L−1. The MRC and SRC adsorption capacities are 71.43 and 69.93 mg g−1, respectively. The adsorption kinetics followed a pseudo-second-order model with MRC and SRC rate constants of 3.40 and 0.83 g mg−1 min−1, respectively. The Freundlich adsorption isotherm is suitable for CV dye adsorption using MRC and SRC with KF values are 1.36 and 1.76 mg g−1 L mg−1 which gives R2 0.943 and 0.932, respectively. These findings showed that the modified RC with magnetite and TEPS effectively removes the CV dye solution through the adsorption process.

“…The adsorption process of a combination is influenced by several factors, including temperature and environmental pH, characteristics of the adsorbed elements, type and amount of adsorbent, and treatment during adsorption, such as contact time and stirring speed [14]. Adsorption methods generally use activated carbon, chitosan, limestone, and quicklime to adsorb dissolved materials in wastewater, such as heavy metal content in wastewater and phenolic waste [15]. The important thing in the adsorption process is selecting the type of adsorbent with high porosity and large surface area [16].…”

Ammonia is a harmful organic substance for aquaculture existence coming from high-protein foods that significantly enhances the growth of white-shrimp. The cultivation rate of artificial feed production increases the water-soluble ammonia load. Unfortunately, not all regional regulations adopt the Minister of Environment Regulation to limit ammonia levels to no more than 5 mg/L. Adsorption is an alternative solution to remove or reduce ammonia levels in liquid waste bodies. This study aims to describe the efficiency of ammonia absorption as a form of environmental management towards sustainable coastal resources, especially in hatchery of vannamei’s. The points of the discussion are the technology used in the adsorbent pre-treatment strategy, laboratory scale, and field tests for the adsorption of water-soluble ammonia. Various types of adsorption materials were compared to determine the best physical and chemical properties to be used as biosorbent. Results of the review show that applying composite technology is able to absorb more ammonia compared to a single material. An important point are finding the right adsorption material and the number of times this material which can be used to adsorb ammonia material. this has an effect on the need for provision costs for waste management in the hatchery.
