“…Adsorption is considered to be an attractive alternative since it stands out through operation simplicity, avoidance of supplementary chemicals, and nonexistence of undesirable products [ 36 ]. Numerous adsorbents such as activated carbon [ 37 , 38 , 39 ], silicates [ 40 ], porous geopolymers [ 41 ], materials prepared from agricultural wastes [ 42 , 43 ] or obtained from biomass residue [ 44 ], materials containing nanoparticles of various oxides [ 45 , 46 , 47 ], composites [ 48 , 49 ], etc., are reported as favorable adsorbents. They possess important surface area, high pore sizes, and structures permitting high affinity with various compounds; therefore, they are listed as efficiently retaining colored contaminants from aqueous media.…”

The treatment of contaminated water is currently a major concern worldwide. This work was directed towards the preparation of a composite hydrogel by entrapping cherry stones powder on chitosan, which is known as one of the most abundant natural polymers. The synthesized material was characterized by scanning electron microscopy, by Fourier transform infrared spectroscopy, and by the point of zero charge determination. Its ability to remove two azo dyes models (Acid Red 66 and Reactive Black 5) existing in single form and in binary mixture was evaluated. Response Surface Methodology–Central Composite Design was used to optimize three parameters affecting the process while targeting the lowest final contaminant concentrations. The best results were obtained at pH 2, an adsorbent dose of 100 g/L, and a temperature of 30 °C, when more than 90% of the pollutants from the single component systems and more than 70% of those of the binary mixtures were removed from their aqueous solutions. The adsorption process was in accordance with Elovich and pseudo-second-order kinetic models, and closely followed the Freundlich and Temkin equilibrium isotherms. The obtained results led to the conclusion that the prepared hydrogel composite possesses the ability to successfully retain the target molecules and that it can be considered as a viable adsorbent material.

“…Temperature was one of the most important factors affecting adsorption, which usually affected the adsorption process by influencing the thermal motion of molecules and promoting or inhibiting the formation of chemical bonds [ 47 ]. The effects of different temperatures (293, 298, 303, 308 K, and 313 K) on the adsorption of organic pollutants by LLB-MB and LLB-MB@Fe 3 O 4 are shown in Figure 9 .…”

Luffa leaf (LL) is an agricultural waste produced by loofah. In this work, LL was used as biomass carbon source for biochars for the first time. After carbonization, activation, and chemical co-precipitation treatments, a magnetic lignocellulose-derived hierarchical porous biochar was obtained. The specific surface area and total pore volume were 2565.4 m2/g and 1.4643 cm3/g, and the surface was rich in carbon and oxygen functional groups. The synthetic dye rhodamine B (RhB) and the antibiotic tetracycline hydrochloride (TH) were selected as organic pollutant models to explore the ability to remove organic pollutants, and the results showed good adsorption performances. The maximum adsorption capacities were 1701.7 mg/g for RhB and 1755.9 mg/g for TH, which were higher than most carbon-based adsorbents. After 10 cycles of use, the removal efficiencies were still maintained at more than 70%, showing good stability. This work not only verified the feasibility of lignocellulose LL as a carbon source to prepare biochar but also prepared a magnetic hierarchical porous adsorbent with good performances that can better treat RhB and TH, which provided a new idea and direction for the efficient removal of organic pollutants in water.

“…MO has been shown to be very hazardous, to damage the eyes, and could potentially result in long-term ocular harm [ 2 ]. Various techniques used for processes used in dye removal, These techniques include for example Ozonation [ 3 ], coagulation–flocculation [ 4 ], Photocatalytic oxidation [ 5 ] Algal treatment [ 6 ], Electrochemical oxidation [ 7 ], Membrane filtration [ 8 ], and adsorption [ [9] , [10] , [11] , [12] , [13] , [14] ]. Due to its adaptability, low cost, and simplicity of use, adsorption is regarded as the best wastewater treatment method.…”
