“…The adsorption capacities of adsorbents for vanadium ions are compared in Table 1. The adsorption capacity of the GO for V(IV) is more than 4 times that of calcium hydroxyapatite, [19] and also higher than that of carbon‐based adsorbents for V(V), [22,37,38] although lower than that of the hydrogel material reported by Jana et al [18] . The better performance of the hydrogel may be due to that the enhanced coordination between the hydrogel and V(IV) in near neutral condition is stronger than the force between GO and V(IV) at the low pH value [39] .…”

Vanadium is a long-confined contaminant. In this study, graphene oxide (GO) was synthesized by the modified Hummers' method and used to remove vanadium(IV). The adsorption isotherms and kinetics of vanadium(IV) on GO at pH 2.5 and three temperatures are measured in batch experiments. The influences of ionic strength is investigated and the regeneration of GO is evaluated by washing with HCl. The results show that the adsorption isotherm corresponds to Temkin model with an adsorption capacity of 70.56 mg/g at 298 K, while the kinetic process coincides with pseudo-secondorder model and approaches to equilibrium in 6 h. The adsorption capacity of GO is not influenced by Na + ionic strength, but sharply inhibited by Ca 2 + . The superior adsorption is dominated by electrostatic interaction, coordination bonding, and hydrogen bonding. Moreover, the GO is reusable, as shown by maintaining 53.4 % of the initial efficacy after five sequential adsorption-desorption cycles.

“…On the other hand, the greater was the dosage, the higher was the percentage removal of TC obtained, which reached 83% for NaX-CD, 54% for NaA-CD, and 47% for NaP1-CD at the adsorbent dosage of 5 g/L. This was due to the increasing number of binding sites when more sorbent was available in the system [60].…”

Modification of zeolites with organic compounds is of increasing interest due to their significant potential in removing emerging pollutants from water. In this work, zeolites from fly ash with three different structure types, NaX (faujasite), NaA (Linde A) and NaP1 (gismondine), were modified with β-cyclodextrin (β-CD), and their adsorption efficacy towards tetracycline (TC) antibiotic in aqueous solutions have been studied. To assess the effect of modification on the zeolites, they were subjected to chemical, mineralogical and surface analyses using X-ray diffraction (XRD), thermogravimetry (TG), scanning electron microscope (SEM), N2 adsorption/desorption isotherm, Fourier-transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The maximum adsorption capacity for NaX-CD, NaA-CD and NaP1-CD was around 48, 60, and 38 mg/g, respectively. The fastest adsorption rate was observed for NaP1-CD, which achieved adsorption equilibria after 200 min, while for NaX-CD and NaA-CD it was established after around 24 h. The kinetic data were best described by the Elovich model, followed by pseudo-second order, while the Sips and Redlich–Peterson models were the most suitable to describe the adsorption isotherms. Based on the adsorption data as well as FTIR and XPS results, TC adsorption efficacy is strongly related to the amount of CD attached to the mineral, and hydrogen bonding formation probably plays the major role between CDs and adsorbate.

“…In addition, there is a need to develop inexpensive and sustainable sorbents from local waste materials. Effective sorbents can be produced from bio-based materials, such as sawdust, and peat, (Gogoi et al 2019(Gogoi et al , 2021bKeränen et al 2016) as well as brucite, which is a readily available magnesium hydroxide-based sorbent. For example, it is possible to obtain a brucite-containing reagent from technogenic waste, which is available in sufficient quantities in the Murmansk region (Krasavtseva et al 2021).…”

Removal of Sulfate and Metals from Wastewater of a Mining Enterprise by a Dual Sorbent System: A Case Study

et al. 2023

View full text Add to dashboard Cite

This paper presents the results of wastewater treatment at a mining enterprise developing a complex ore deposit in the Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this complex wastewater treatment, a two-stage scheme was proposed and tested using two sorbents (at a pH of 6): an aminated peat biosorbent to remove sulfate and a commercial sorbent based on the mineral brucite to remove metals. Optimal conditions were established for purifying the wastewater of sulfate and manganese and strontium ions to the level of maximum available concentrations in water bodies for fishery purposes.
