“…A similar trend was observed in the study of the anaerobic tank effluent. All P concentrations dropped to the discharge standard (0.5 mg/L) in 20 mL of real wastewater with the addition of 0.05 g of adsorbent. These results are encouraging and confirm the potential of Fe 3 O 4 /PAM/SA–Zr for phosphate removal in practical applications.…”

Amino‐functionalized magnetic zirconium alginate beads with an interpenetrating network (Fe3O4/PAM/SA–Zr) were prepared, characterized, and then tested as a novel biomass adsorbent for phosphate removal and recovery. The hydrogel beads exhibited outstanding thermostability and possessed a magnetic response. The effects of the pH, dosage, initial phosphate concentration, interference ions, and temperature on the removal of phosphate were investigated. The kinetics, isotherms, and thermodynamics of the adsorption were studied. Notably, the adsorption of phosphate was endothermic, feasible, and spontaneous with a maximum uptake capacity of 42.23 mg‐P/g at an optimized pH of 2.0. The phosphate could be desorbed effectively with a 0.2 mol/L NaOH solution, and the adsorbent exhibited a good reusability. The possible adsorption mechanisms were verified by zeta potential, Fourier transform infrared spectroscopy, and X‐ray photoelectron spectroscopy analyses. Continuous phosphate‐adsorption tests were conducted in a fixed‐bed columns packed with Fe3O4/PAM/SA–Zr, and the breakthrough curves were predicted by the Adams–Bohart, Thomas, and Yoon–Nelson models, respectively. The suitability of the hydrogel beads for the treatment of real wastewater was also tested. These hydrogel beads should be a promising adsorbent for phosphate removal and recovery from aqueous solutions, with the advantages of a high uptake capacity, good reusability, and easy magnetic separation. © 2018 Wiley Periodicals, Inc.

“…The diminishing supply 11 of phosphorus necessitates the consideration of its recovery from 12 wastewater streams [2]. On the other hand, excessive phosphorus 13 in wastewater usually results in eutrophication in rivers and lakes, 14 which is an issue of global concern [3,4]. Employment of an 15 efficient method for reducing and recycling phosphates during 16 wastewater treatment is a fundamental factor in preventing 17 eutrophication.…”

“…Among 21 various available technologies for phosphate decontamination, the 22 adsorption method is relatively simple, economical, and highly 23 efficient [5,6]. Various types of materials have been used as 24 adsorbents, such as Fe-Mn binary oxide [7], a metal oxide 25 adsorbent derived from manganese ore tailings [8], nanostruc- 26 tured Fe(III)-Cu(II) binary oxides [9], mesoporous Cr-Zr binary 27 oxide nanoadsorbent [10], magnetic Fe-Zr binary oxide [11], 28 aluminum compounds [12][13][14], and hydrous zirconium oxide- 29 based nanocomposites [4]. Composite metal oxides may show 30 physicochemical properties different from those of their single- 31 component oxide counterparts.…”

“…Composite metal oxides may show different physicochemical properties from those of their single-component counterparts [22]. For instance, Al-Fe hydroxide, mesoporous Cr-Zr binary oxide nanoadsorbent, hydrous zirconium oxide-based nanocomposites, and Fe-Al-Mn trimetal oxide have been reported as phosphate-ion-removal agents [24][25][26][27]. In addition, we previously reported that nickel hydroxide, cobalt hydroxide, and cobalt-containing nickel hydroxide show sufficient capabilities for phosphate ion adsorption [20,22,28].…”

In this study, nickel hydroxide containing cobalt as a co-precipitation hydroxide (NiCo91) was granulated with a binder (polyethylene terephthalate, PET) and characterized (scanning electron microscopy, specific surface area, amount of hydroxyl groups, and surface pH). In addition, the phosphate ion adsorption capability of the granulated adsorbent was evaluated by examining the effects of contact time and solution pH, analysis of adsorption isotherms, and a desorption study. It was confirmed that NiCo91 calcined at 270°C could be granulated using a PET binder. The specific surface area (32 m 2 /g) and hydroxyl group amount (0.19 mmol/g) of PET20S (20% binder content and < 500 μm particle diameter) were greater than those of other adsorbents. The amount of the adsorbed phosphate ions was greater for PET20S than that for other adsorbents, indicating that the adsorbent surface properties were related to the adsorption of phosphate ions. The phosphate ions adsorbed onto PET20S could be desorbed by different concentrations of sodium hydroxide, and at least three-fold increase in adsorption/desorption onto PET20S could be obtained. The results show that PET20S is highly promising as a renewable adsorbent of phosphate ions from aqueous solutions.
