“…is availability favors their occupation by the molecules of phenacetin. e same trend was observed by Gadipelly et al [16] during the adsorption of ciprofloxacin onto MOF-5 (zinc (II) benzene dicarboxylate). As the adsorption continues, the number of available sites decreases and the adsorbent becomes saturated.…”

“…However, the adsorption method has many advantages over the others, such as easy operation, high efficiency, and no risk of highly toxic sub-products [8]. e most used adsorbents for the removal of pharmaceutical compounds from aqueous solution are activated carbons [9][10][11] clay minerals [12], polymeric resins [13], and other adsorbents, such as molecular polymers [14], mesoporous materials [15], and metalorganic frameworks [16]. Despite all these, it is still of interest to study modified adsorbents or new adsorbents that may be more efficient at removing pharmaceutical compounds from water than conventional ones.…”

Two coordination compounds, copper (II) fumarate (CuFum) and copper (II) tartrate (CuTart), synthesized from copper (II) with fumaric acid and tartaric acid as ligands and using the slow evaporation method have been applied to study the adsorption of phenacetin in aqueous solution. These compounds were characterized by elemental analysis, IR-FT spectroscopy, and X-ray powder diffraction. The melting points of the synthesized coordination compounds were found to be above 350°C. The influence of parameters such as the initial pH, the contact time, and the initial concentration on the adsorption of phenacetin in an aqueous solution has been studied. The studies showed that adsorption equilibrium was reached after 80 minutes for both coordination compounds; the adsorption capacity increased with increasing phenacetin concentration, and the maximum adsorption capacity was obtained in the acidic medium at pH 4. The adsorbed amount of phenacetin on copper (II) fumarate (CuFum) was 25.158 mg/g while that on copper (II) tartrate (CuTart) was 25.906 mg/g. Nonlinear regression analysis showed the best fit for the Freundlich model isotherm for CuTart with R2 of 0.963 and a Chi-square test (χ2) of 0.529 while for the CuFum material, it is the Redlich-Peterson model with R2 of 0.975 and Chi-square test (χ2) of 0.263. The kinetic study shows that the pseudo-second-order model better describes the adsorption of the two materials. The results show that physisorption and chemisorption participate in the adsorption of phenacetin and that these materials can be used for the elimination of phenacetin in solution.

“…Ciprofloxacin hydrochloride was recently removed by using MOF-5 in the aqueous phase. The adsorption capacity of MOF-5 (98 mg/g) was higher than that of AC (65 mg/g) because of the electrostatic interactions between ciprofloxacin and the MOF-5 surface . The adsorption capacities of ibuprofen, indomethacin, furosemide (NSAIDs), ketoprofen, and naproxen on UiO-66 were reported to be the highest among the following adsorbents (AC, carbon nanotubes, graphenes, resins, zeolites, and other MOFs) …”

Pharmaceuticals of Emerging Concern in Aquatic Systems: Chemistry, Occurrence, Effects, and Removal Methods

In the last few decades, pharmaceuticals, credited with saving millions of lives, have emerged as a new class of environmental contaminant. These compounds can have both chronic and acute harmful effects on natural flora and fauna. The presence of pharmaceutical contaminants in ground waters, surface waters (lakes, rivers, and streams), sea water, wastewater treatment plants (influents and effluents), soils, and sludges has been well doccumented. A range of methods including oxidation, photolysis, UV-degradation, nanofiltration, reverse osmosis, and adsorption has been used for their remediation from aqueous systems. Many methods have been commercially limited by toxic sludge generation, incomplete removal, high capital and operating costs, and the need for skilled operating and maintenance personnel. Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method. Adsorption remediation methods are easily integrated with wastewater treatment plants (WWTPs). Herein, we have reviewed the literature (1990–2018) illustrating the rising environmental pharmaceutical contamination concerns as well as remediation efforts emphasizing adsorption.

Recent Progress in Adsorptive Removal of Water Pollutants by Metal‐Organic Frameworks

Difficulty in accessing drinkable water resources, mostly originating from water pollution, has become a serious challenge for humans and the environment. Increasing population, growth of industrial activities, and the increasing demand for the agricultural sector have generated various pollutants into the environment, especially water resources. Thus, treatment of industrial effluents before discharging them into the environment is necessary to reduce the pollutants, maintain the quality of drinkable water, recycle wastewater sources to save water consumption, and minimize water resource supplied. Among the new materials applied for the adsorptive removal of pollutants from aquatic environments, metal‐organic frameworks have become a promising candidate to optimize wastewater treatment process. This is mainly due to their unique properties such as structural diversity, high specific surface area, and high adsorption capacity. This article aims to review the highlights and challenges of MOFs when are being used to remove heavy metals, dyes, pharmaceuticals, personal care products, pesticides, and herbicides from polluted water resources. The relationship between the properties of MOFs and their performance for adsorption of pollutants as well as the key mechanisms of adsorbing water pollutants using MOFs are presented. The use of water‐stable MOFs such as MOF‐235, MIL‐53, MIL‐100, MIL‐101, UiO‐66, ZIF‐67, and ZIF‐8 will be discussed for removing various pollutants. The adsorption efficiency of functionalized MOFs, magnetic MOFs, MOF‐polymer, graphene oxide‐MOF, and CNT‐MOF composites will be reviewed in comparison with commercial adsorbents such as zeolites and activated carbon. As for the conclusion, the challenges and outlooks of applying MOFs and MOF‐based materials for the adsorptive separation of water pollutants are summarized.
