“…erefore, trace of Ce +2 0.1% has been investigated by the elemental analysis. Figure 1 (a) shows the PXRD pa ern for UiO-66 samples, it was demonstrated that the structures were the same, similar to that in previous reported articles [15,22]. In addition, FTIR spectra of the samples in this study was shown in Figure1 (b), all functional groups which were seen on the surface of UiO-66 in previous studies [23] were observed and maintained on the surface of UiO-66-Ce and modified UiO-66.…”

“…Figure 6 shows that all values of R L are between 0 < R L < 1 confirming that the normal adsorption of MO on UiO-66 samples are favourable. RL approached to zero at high concentration indicated that a further increasing in initial concentrations might lead to irreversible adsorption due to enhancing the a raction force with increasing the initial concentrations [22]. updated UiO-66 samples ey were synthesised in single pot solvothermal methods.…”

In this study, two improved versions of UiO-66 were successfully synthesised. Modified UiO-66 and UiO-66-Ce were characterised to confirm the integrity of the structure, the stability of functional groups on the surface and the thermal stability. Activated samples were used for removal harmful anionic dye (methyl orange) (MO) from wastewater. Batch adsorption process was relied to investigate the competition between those MOFs for removing MO from aqueous solution. Based on the results, at a higher initial concentration, the maximum MO uptake was achieved by UiO-66-Ce which was better than modified-UiO-66. They adsorbed 71.5 and 62.5 mg g-1 respectively. Langmuir and Freundlich isotherms were employed to simulate the experimental data. In addition, Pseudo first order and Pseudo second order equations were used to describe the dynamic behaviour of MO through the adsorption process. The high adsorption capacities on these adsorbents can make them promised adsorbents in industrial areas.

“…An adsorbate solution (stock) with a concentration of 1000 mg/L was prepared using an analytical-reagent grade of MEG (C 2 H 6 O 2 ). The stock solution was diluted to prepare a series of MEG concentrations (25,50,75,100,125, and 150 mg/L), as reported by Zaboon et al [5]. The pH values of the MEG phase were adjusted using 0.1 M solutions of either HCl or NaOH.…”

“…Petrochemical industrial wastewater laden with MEG is characterized by poor biodegradability, high toxicity, and carcinogenicity [4]. In addition, petrochemical effluents pose serious threats to human health, including damages of the brain, eyes, kidneys, and nervous system; or even death at high doses [5]. They also tend to deteriorate the environment and ecosystems; hence, removing MEG from the aquatic environment is of great importance.…”

Synthesis of sludge-derived biochar modified with eggshell waste for monoethylene glycol removal from aqueous solutions

In this study, the pyrolysis of sewage sludge was employed to prepare a biochar (BC) adsorbent that was modified using eggshell wastes, obtaining eggshell-modified biochar (EMBC). The adsorbent material was used for the removal of monoethylene glycol (MEG) from aqueous solutions under various adsorption conditions. Results showed that the specific surface area of EMBC (i.e., 3.95 m 2 /g) was approximately twofold higher than that of BC, implying that the application of eggshell waste would improve the surface adsorption performance. The optimum adsorption pH value was 7, achieving MEG removal efficiencies of 29.9% for BC and 89.9% for EMBC using adsorbent dosage = 2 g/L, initial MEG concentration = 100 mg/L, and 25 °C within 60 min. The adsorption mechanisms were illustrated regarding XRD, FTIR, and SEM, demonstrating that surface adsorption, pore-filling, precipitation, and complexation contributed to the adsorption process. The adsorption data fitted well to the Langmuir isotherm model with the maximum monolayer adsorption capacity of 12.20 mg/g, implying a reversible physisorption mechanism. Based on a techno-economic feasibility assessment, the preparation of BC and EMBC adsorbents for the treatment of 1 m 3 of wastewater-containing ethylene glycol would require capital costs of 4.80 and 6.50 US$, respectively. The selling of adsorbents and the economic benefit of tertiary treated water showed adequate annual profitability with payback periods of 12.97 and 6.79 years for the BC and EMBC scenarios, respectively. Hence, the study succeeded in preparing efficient and low-cost adsorbents that could be used for the tertiary treatment of petrochemical industrial wastewater containing toxic environmental pollutants.

Metal organic framework (MOF) hybrid materials could be one of the answers in this investigation. We describe a simple and effective encapsulation of doxorubicin (DOX), an anticancer drug, inside Zr-MOF, which have been little studied as drug delivery organizations. We investigated the measured release of the drug from Zr-MOF in response to external incentives such as pH changes and interaction with biomimetic schemes. Zr-MOF with encapsulated doxorubicin (DOX@Zr-MOF) can be manufactured in one pot by addition the anticancer medication DOX to the reaction combination. They demonstrated pH-responsive medication release and cancer cell killing capability. MOFs can be designed as multifunctional distribution vehicles for a diversity of loads, including medicinal and imaging agents, using our simple one-pot approach.Fourier transform infrared (FTIR), X-ray diffraction, scanning electron microscopy, and N 2 sorption isotherm were used to analyze MOF and the developed drug delivery (DOX@Zr-MOF) scheme. It investigated the effects of MOF and a bespoke drug delivery system on the feasibility of patient breast as well as liver tumor cell lines. At pH 5, the trapped drug can be released more quickly than at pH 7.4. Zr-MOF nanoparticles had modest cytotoxicity; however, DOX@Zr-MOF has higher cytotoxicity in MCF-7 and HepG-2 cells than DOX at concentrations greater than 31.25 μg ml À1 . These results were discovered
