“…A soluble dye usually forms a variety of ionic dyestuffs quickly in water, but this dye can also reduce the photosynthetic activities of hydrophytes and pose a possible hazard to human [10][11][12] and aquatic life [13]. Several techniques have been developed to remove dyes from wastewater: bioremediation, chemical precipitation, oxidation, and adsorption [14]. Adsorption is regarded as effective and economical due to its low cost, toxic tolerance, simple design, and ease of operation [10,15].…”

Recycling and reusing glass fiber waste (GFW) has become an environmental concern, as the means of disposal are becoming limited as GFW production increases. Therefore, this study developed a novel, cost-effective method to turn GFW into a mesoporous zeolite-like nanomaterial (MZN) that could serve as an environmentally benign adsorbent and efficient remover of methylene blue (MB) from solutions. Using the Taguchi optimizing approach to hydrothermal alkaline activation, we produced analcime with interconnected nanopores of about 11.7 nm. This MZN had a surface area of 166 m2 g−1 and was negatively charged with functional groups that could adsorb MB ranging from pH 2 to 10 and all with excellent capacity at pH 6.0 of the maximum Langmuir adsorption capacity of 132 mg g−1. Moreover, the MZN adsorbed MB exothermically, and the reaction is reversible according to its thermodynamic parameters. In sum, this study indicated that MZN recycled from glass fiber waste is a novel, environmentally friendly means to adsorb cation methylene blue (MB), thus opening a gateway to the design and fabrication of ceramic-zeolite and tourmaline-ceramic balls and ceramic ring-filter media products. In addition, it has environmental applications such as removing cation dyes and trace metal ions from aqueous solutions and recycling water.

The aim of this study is modeling of the process of Ni(II) removal onto new materials synthesized by a facile coprecipitation method. The literature presents different surfactants intercalated on MgAl-LDH with applicability for nickel ions removal, but the researches on the use of this material ��as cast�� as adsorbent for Ni(II) ions are limited, it is reason to develop this study. The morphology, chemical composition, and the basic structure of the new material were analyzed by SEM, EDAX, BET, XRD and FT-IR. The kinetic modeling was performed using the pseudo-first-order, four-type linear pseudo-second-order, and intraparticle diffusion. The experimental data demonstrated that the adsorption process is very fast in the first 20 minutes and reach equilibrium after 50 min. The maximum adsorption capacities of the adsorbent are in the range of 36.5-68.18 mg/g, for the 200-500 mg/L initial solution concentration.

“…For both adsorbents, ion exchange was the governing mechanism after electrostatic attraction dominated for the first few minutes. Grover, Mohiuddin, Malik, Aulakh, and Kim (2019) prepared LDH with the urea hydrolysis method with the embolism of dodecylsulfate into LDH (DS-Zn/Al LDH). The dodecylsulfate intercalation made the LDH surface hydrophobic, which would be favorable to the organics' adsorption.…”

By summarizing 187 relevant research articles published in 2019, the review is focused on the research progress of physicochemical processes for wastewater treatment. This review divides into two sections, physical processes and chemical processes. The physical processes section includes three subsections , that is, adsorption, granular filtration, and dissolved air flotation, whereas the chemical processes section has five subsections , that is, coagulation/flocculation, advanced oxidation processes, electrochemical, capacitive deionization, and ion exchange.
