“…Adsorption is widely applied in industries since it offers a low-cost and effective method to treat highly polluted water. , The technology is relatively simple while adsorbents can be easily regenerated and recycled for further uses. Recently, nanoporous adsorbents have been developed and effectively applied to remove metal ions from industrial wastewater as shown in Figure . , The fundamental of this application is to develop a highly porous nanoscale material with a large surface area to absorb the metal irons which can be selectively designed to target a specific metal. Significantly, the nanomaterials can be regenerated using a desorbing agent that is not harmful to the environment.…”

Removal of heavy metals in wastewater treatment is crucial to protect the environment, wildlife, and human health. Various techniques have been developed focusing on removal of heavy metal ions, pharmaceuticals, and other contaminants from different wastewater sources. The main methods include adsorption, filtration, ion exchange, electrochemical, reverse osmosis, precipitation, flotation/coagulation/ flocculation, and photocatalytic-based treatments. This paper comprehensively assesses the sustainability of those common technologies used for wastewater process treatment. The sustainability profile depends mostly on the exact approach followed for each technology, including its energy consumption, type of radiation (where appropriate), auxiliary materials used (e.g., catalysts, adsorbents), and further specific experimental process settings. Thus, while sustainability inevitably provides a multifaceted answer, the review finally aims for sustainability benchmarking of all technologies, by compressing the manifold outcomes toward a compact information set, such as a table and radar plot.

“…There are currently a variety of adsorbents used in removal studies, including adsorbents to inorganic material bases such as clay, metals, and oxides, carbon adsorbents, etc. [92,119,120]. However, polymer applications have become a major source of solutions to the problem of organic pollutants [121].…”

In recent decades the presence of pollutants has grown considerably around the world, along with the scarcity of fresh water. One of the environmental problems that has intensified lately is the presence of antibiotic resistant strains and the appearance of resistant genes due to the misuse and high worldwide consumption of this type of pharmaceutical products. Therefore, the number of investigations has been intensified to address these great problems that can affect public health and cause great economic losses around the world. For this reason, in this review, different antibiotics removal techniques in water have been compiled and analyzed critically.

“…10 Several conventional techniques have been introduced such as photochemical, photocatalytic degradation, ion exchange treatment, adsorption, oxidation, membrane filtration, and ozonation for the removal or degradation of organic pollutants from the water. [11][12][13][14][15][16][17][18] Adsorption is one of the most effective, safe, and non-toxic ways to remove organic pollutants. 5,19 For the removal of organic dyes, there are many adsorbent materials reported in Reference 20.…”

“…27,34,35 However, there are certain limitations like high synthesis cost, reusability, low stability in water, and selective adsorption of organic pollutants, which can be resolved by introducing MOF-derived materials. 12 Layered double hydroxides also called anionic clay are interesting hydrotalcite-like compounds. These are low in cost and have interesting properties like high surface area, resistance to thermal change, good ion exchange treatment, tunable behavior, simple preparation, and extensive pH variation range.…”

The development of highly efficient and cost‐effective materials for water treatment is paramount and the preparation of metal–organic framework‐derived layer double hydroxide (MOF‐LDH) is an area of great interest. In this study, an innovative adsorbent material zeolitic imidazole framework‐8 (ZIF‐8) derived ZnCo layered double hydroxides was prepared by in situ growth for the adsorption of cationic methylene blue (MB) dye from wastewater. Analytical tools such as FTIR, SEM, and XRD were used to characterize the composite material. Different adsorption parameters like initial dye concentration, pH, temperature, contact time, adsorption mechanisms, and density functional theory (DFT) mechanisms were studied which showed that the derived material significantly enhanced the adsorption capacity which was 502.51 mg/g at pH 11. DFT analyses suggested that MB possessed interaction sites favorable to adsorbent material. The adsorption kinetic model showed that pseudo‐second‐order had a good correlation coefficient (R2 = 0.99983) value proposing the chemisorption adsorption phenomenon. Both the Langmuir and Freundlich isotherm models are well fitted in experimental data as both have good correlation coefficient (R2 = 0.99771) and (R2 = 0.99856) values respectively but the best fit of the adsorption isotherm data was achieved with the Freundlich model, indicating multilayer adsorption characteristics. The experimental and theoretical analyses demonstrated that the fabricated adsorbent is a highly efficient material for the adsorption of organic pollutants from an aqueous medium.
