“…The thermodynamics studies provide information about whether the adsorption of Fe(II) on both adsorbents is feasible and spontaneous or not. Three thermodynamic parameters, including the standard free-energy change (ΔG o ), standard entropy change (∆S o ), and standard enthalpy change (∆H o ) were calculated at temperatures varying from 25 to 55 °C by the following equations (10) and (11):…”

In this work, a new mesoporous activated carbon from waste corrugated fiberboard (WCF) and waste paper (WP) were prepared via chemical activation impregnation with zinc chloride at different temperatures as a low cost, eco-friendly, and effective biosorbent for elimination of Fe(II) from the aqueous solution. The morphology and surface properties of ACWCF and ACWP were characterized by, scanning electron microscopy (SEM), Boehm's titration, specific surface area (BET), and Fourier transform infrared spectrometer (FTIR). The results showed that the ACWCF and ACWP had a high surface area of 1110.99 m2/g and 298.59 m2/g, respectively. Batch experiments tested the influence of pH, initial Fe(II) concentration, adsorbent mass, contact time, and temperature on the adsorption process. The adsorption kinetics could be expressed well by the PSO model. The adsorptions of Fe(II) onto ACWCF and ACWP were fitted best using the Langmuir and Dubinin- Radushkevich isotherm models with maximum capacities of 66.66 mg/g and 41.67 mg/g at 55°C, respectively. The adsorption process on ACWCF and ACWP may be controlled for both electrostatic interaction mechanisms. Based on the above results, it can be concluded that the ACWCF is effective adsorbent for the elimination of Fe(II) from aqueous solutions

Metal–organic framework (MOF) synthesis has been studied for over 50 years, yet its use in adsorbing herbicides is still under investigation. This study examined the effects of amino‐MIL‐101(Fe) on the adsorption and removal of atrazine (AZ). The novel amino‐MIL‐101(Fe) nanoadsorbent has been completely characterized after and before the adsorption process using Fourier‐transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM), X‐ray diffraction (XRD), energy‐dispersive X‐ray photoelectron spectroscopy (XPS), and nitrogen adsorption–desorption isotherm. The Brunauer–Emmett–Teller (BET) surface area of the novel amino‐MIL‐101(Fe) nanoadsorbent before and after five‐time reuse were 1222 and 1038 m2/g, respectively. The amino‐MIL‐101(Fe) nanoadsorbent was found to have the greatest adsorption capacity (qmax) of 321.55 mg/g. Variables such as herbicide concentration, pH, adsorbent dosage, and temperature that affect the adsorption process have been investigated. It was found that the ideal conditions for high adsorption capacity were pH 4 and a dose of 0.02 g. The adsorption isotherm and the kinetic isotherm were fitted to the Langmuir equation and the pseudo‐second‐order equation, respectively. The chemisorption mechanism was identified as the driving force. According to adsorption thermodynamics, the adsorption process was spontaneous and endothermic. The quantities of AZ adsorbed grew along with the temperature. The amino‐MIL‐101(Fe) nanoadsorbent can be reused up to five times with no change in its chemical composition and identical results from XRD before and after reuse. The mechanism of interaction by which the amino‐MIL‐101(Fe) interacted with the AZ has been represented.
