“…The experimental data were analyzed using various isotherm models (Freundlich, Langmuir, Sips, and Redlich-Peterson [ 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ], which are described in more detail in the Supplementary Data ), providing important information about the sorption processes. The applicability of the isothermal model is mainly determined by comparing the correlation coefficients R 2 [ 59 ].…”

Magnetically Modified Biosorbent for Rapid Beryllium Elimination from the Aqueous Environment

et al. 2021

Although both beryllium and its compounds display high toxicity, little attention has been focused on the removal of beryllium from wastewaters. In this research, magnetically modified biochar obtained from poor-quality wheat with two distinct FexOy contents was studied as a sorbent for the elimination of beryllium from an aqueous solution. The determined elimination efficiency was higher than 80% in both prepared composites, and the presence of FexOy did not affect the sorption properties. The experimental qmax values were determined to be 1.44 mg/g for original biochar and biochar with lower content of iron and 1.45 mg/g for the biochar with higher iron content. The optimum pH values favorable for sorption were determined to be 6. After the sorption procedure, the sorbent was still magnetically active enough to be removed from the solution by a magnet. Using magnetically modified sorbents proved to be an easy to apply, low-cost, and effective technique.

“…Successful removal of metal ions from crude phosphoric acid suggests that the Marathon C resin could be used in removing toxic metal ions from crude phosphoric acids used in phosphate fertilizer production. [24] Pehlivan and Altun studied the ion exchange of Cd 2+ , Cu 2+ , Zn 2+ , Ni 2+ , and Pb 2+ from aqueous solutions with Dowex 50W synthetic resin. [25] The structural polymeric backbone of the resin is styrene cross-linked with DVB, functionalized with sulphonic acid group in sodium form as the ion exchange site.…”

Adsorption and removal studies of cadmium ion onto sulphonic/phosphonic acid functionalization resins

Cadmium is a persistent bio‐accumulative toxic metallic element, which causes hazardous impacts on living species, water, and the environment. This paper presents the study of cadmium ion removal from aqueous solutions in batch experiments using 22 ion exchange resins with different functional groups. It was found that Dowex G‐26 resin with a sulphonic functional group and Puromet™ MTS9570 resin with sulphonic and phosphonic functional groups had excellent performance for Cd (II) ion removal. The effects of resin dosage, adsorption time, initial concentration of cadmium, and initial pH of solution on cadmium removal were investigated systematically using Dowex G‐26 and Puromet™ MTS9570 resins. Maximum cadmium removal rates of 99.2% and 98.9% were achieved for G‐26 and MTS9570, respectively, at an initial cadmium concentration of 1000 mg/L, an initial solution pH of 5.0, an adsorption time of 30 min, and a 0.01 mg/L resin dosage for G‐26, and a 0.025 mg/L resin dosage for MTS9570. The ion‐exchange adsorption process was fast, and it reached equilibrium after 30 min of adsorption. The results obtained show that both resins performed well for the removal of Cd (II) ions from weakly acidic solutions. Langmuir, Freundlich, and Temkin isotherms models were employed to investigate and understand the adsorption characteristics. The results showed that the studied adsorption processes fitted well to the Langmuir adsorption isotherm. From the Langmuir adsorption isotherm, the maximum adsorption capacities of Cd (II) were found to be 78.125 and 51.020 mg/g for G‐26 and MTS9570, respectively. This research provides an efficient systemic approach for cadmium ion removal from aqueous solutions.

“…(Qiu et al, 2021;Zhao et al, 2021;Zhong et al, 2021a). At present, various methods had been used to U(VI) removal and enrichment, including adsorption (Wang et al, 2021b;Zhong et al, 2021b), cation exchange (Taha, 2021;Venkateswara Rao et al, 2021), electrochemical treatment (Potgieter et al, 2020), photocatalytic treatment (Lei et al, 2021;Li et al, 2019), chemical precipitation (Lu et al, 2019;Zheng et al, 2020), etc. In practical applications, adsorption became the most promising U(VI) separation and enrichment methods, attributing to its advantages of low cost, straightforward operation, fast speed, high adsorption capacity and selectivity, and wide-ranging raw materials.…”

In recent years, the synthesis and application of green, cost-effective and sustainable materials for uranium (VI) removal was signi cant to environmental protection. The ordered mesoporous carbon (CMK-3) supported different mass of hydroxyapatite materials (HAP@CMK-3) were facilely synthesized via hydrothermal method. The resultant materials were characterized by XRD, FT-IR, BET, SEM, TEM-mapping and XPS, and implemented for immobilizing U(VI). Not only the speci c surface area of HAP (7.01 m 2 /g) was increased by the loading on CMK-3 (818.37 m 2 /g), but also the adsorption capacity of CMK-3 was increased by HAP modi cation.Impressively, HAP@CMK-3 exhibited highly adsorption capacity of U(VI) with the increase of HAP deposition and was capable of achieving fast reaction. Therein to, the speci c surface area of HAP@CMK-3(2:1) was 253.68 m 2 /g, as well as the adsorption capacity was up to 1072 mg/g ( tted by Langmuir isotherm, at pH = 3.0, 298 K) and the adsorption process was completed in 30 min (followed by pseudo-second-order kinetic).
