“…The maximum adsorption capacity of activated carbons for caffeine is often correlated to the micropore volume, caused by the small critical diameter of 0.45 nm (Galhetas et al, 2014). The activated biochars in this study showed similar or higher adsorption capacity towards caffeine (except WSP) compared to values reported for activated carbons in a recent review (Anastopoulos et al, 2020).…”

Magnetic carbons can significantly lower the costs of wastewater treatment due to easy separation of the adsorbent. However, current production techniques often involve the use of chlorinated or sulfonated Fe precursors with an inherent potential for secondary pollution. In this study, ochre, an iron-rich waste stream was investigated as a sustainable Fe source to produce magnetic activated biochar from two agricultural feedstocks, softwood and wheat straw. Fe-doping resulted in significant shifts in pyrolysis yield distribution with increased gas yields (+50 %) and gas energy content (+40 %) lowering the energy costs for production. Physical activation transformed ochre to magnetite/maghemite resulting in activated magnetic biochars and lead to a 4-fold increase in the adsorption capacities for two common micropollutants-caffeine and fluconazole. The results show that Fe doping not only benefits the adsorbent properties but also the production process, leading the way to sustainable carbon adsorbents.

“…Adsorption method has obvious advantages, such as simple operation, high efficiency, and the adsorbent can be reused [ 25 , 26 , 27 , 28 ]. However, some porous adsorption materials are expensive, therefore seeking to prepare new adsorption materials with excellent performance and low price has become a research hotspot of scholars at home and abroad [ 29 , 30 , 31 , 32 , 33 ].…”

In order to obtain low-cost and excellent adsorption materials, this paper used calcium acetate and water glass as raw materials to synthesis hydrated calcium silicate gel by precipitation method. The performance and structure of hydrated calcium silicate gel were systematically studied by X-ray photoelectron spectroscopy, fourier transform infrared spectroscopy, specific surface area analyzer and scanning electron microscope. Studies have shown that, non-crystal hydrated calcium silicate gel (CSH) were successfully prepared, and the removal rate of lead ion using CSH reached more than 90%. The adsorption process is consistent with the pseudo-second-order kinetic model and Langmuir adsorption isotherm model, and the limit adsorption capacity reaches 263.17 mg·g−1. The acid treatment experiment proved that the adsorption capacity of lead ion using CSH was satisfactory, and the adsorption rate remained at >60% after 5 cycles. The research may provide a low-cost, high-efficiency and high stability adsorbent.

“…Over the years, various remediation techniques such as coagulation, flocculation, membrane filtration, precipitation, ion exchange, chemical oxidation, biodegradation and adsorption have been applied to remove pollutants from water [ 15 ]. Of these methods, adsorption has been singled out to be the most practical and promising technique due to its low cost, simple operations, high selectivity, environmentally benign, convenient recycling and availability of various adsorbents materials [ 16 ]. Some adsorbents such as activated [ 17 , 18 ], biochar [ 19 ], clay minerals [ 8 ] and goethite [ 20 ] have been previously used for MCPA adsorption.…”

Removal of 4-chloro-2-methylphenoxyacetic acid from water by MIL-101(Cr) metal-organic framework: kinetics, isotherms and statistical models

Effective removal of 4-chloro-2-methylphenoxyacetic acid (MCPA), an emerging agrochemical contaminant in water with carcinogenic and mutagenic health effects has been reported using hydrothermally synthesized MIL-101(Cr) metal-organic framework (MOF). The properties of the MOF were ascertained using powdered X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, thermal gravimetric analysis (TGA), field emission scanning electron microscopy (FESEM) and surface area and porosimetry (SAP). The BET surface area and pore volume of the MOF were 1439 m 2 g −1 and 0.77 cm 3 g −1 , respectively. Artificial neural network (ANN) model was significantly employed for the accurate prediction of the experimental adsorption capacity ( q e ) values with minimal error. A rapid removal of the pollutant (99%) was recorded within short time (approx. 25 min), and the reusability of the MOF (20 mg) was achieved up to six cycles with over 90% removal efficiency. The kinetics, isotherm and thermodynamics of the process were described by the pseudo-second-order, Freundlich and endothermic adsorption, respectively. The adsorption process is spontaneous based on the negative Gibbs free energy values. The significant correlation between the experimental findings and simulation results suggests the great potential of MIL-101(Cr) for the remediation of MCPA from water matrices.
