The recovery of phosphorus from source-separated urine by repeatedly usable magnetic Fe3O4@ZrO2 nanoparticles under acidic conditions

Environment International (2019)

Tong Guan Yue Kuang Xiaodi Li Jing Fang Wenkan Fang

The separation of urine at source for phosphorus (P) recovery is attractive taking into account the high P concentration and small volume. However, the treatment of urine is still challenging due to its unpleasant odor and hygiene problems. Because the above problems could be solved by acidification to keep the pH of urine below 4, we propose a novel strategy to recover P from acidified urine using tailored hydrous zirconia-coated magnetite nanoparticles (Fe3O4@ZrO2). This strategy involves the selective adsorption of phosphate by easily separable and reusable Fe3O4@ZrO2, the desorption of adsorbed phosphate, and the precipitation of desorbed phosphate as calcium phosphate fertilizer. The results indicated that at pH 4, the P in synthetic urine was selectively adsorbed and could be exhausted using Fe3O4@ZrO2. Nearly all (>97.5%) of the sequestered P on the Fe3O4@ZrO2 nanoparticles was stripped using ≥1 M NaOH solution and ~100% of the stripped P was then successfully transformed into calcium phosphate, upon adding CaCl2 at pH >12 and a Ca/P molar ratio of 3. The liquid/solid (Fe3O4@ZrO2 particles) mixture could be conveniently separated for reuse using an external magnetic field. The reusability of the Fe3O4@ZrO2 nanoparticles in the extraction of P from synthetic urine was confirmed using five cycles of the adsorption-desorption process and their performance validated using real urine samples. The mechanism of phosphate adsorption was investigated using XPS, FTIR and zeta potential measurements, showing that phosphate was chemically adsorbed on the surface through direct coordination to zirconium atom via ligand exchange.

Dynamic Elution of Residual Ion-Exchangeable Ammonium from Weathered Crust Elution-Deposited Rare Earth Tailings

SSRN Electronic Journal (2022)

Ze Ouyang Xiaoju Li Junxia Yu Xiaodi Li Haobo Hou

Ion-exchangeable ammonium (IEA), as one of the major existing forms of residual ammonium in weathered crust rare earth tailings, has great potential to be released under natural conditions, which may lead to serious environmental pollution. Herein IEA distribution feature was determined, and five common ions (Al3+, Ca2+, Mg2+, Na+, and K+) were used as eluent to remove IEA from the tailing. Elution process and mechanism were studied in details. The results showed that IEA was mainly concentrated on illite which accounts for the largest proportion of the rare earth clay minerals (>65%). During the elution process, the metal ions initial concentration, flow rate, and particle size affected IEA removal efficiency while pH exhibited only a small effect, and the elution rate was controlled by internal diffusion. Among the selected eluents, the elution efficiency decreased in the order K+>Mg2+>Al3+>Ca2+>Na+. The highest elution efficiency of IEA can reach 95.94% at an initial K+ concentration of 0.1 mol/L, pH 5.0-7.0, and a flow rate of 2.5 mL/min. Characterization results demonstrated that IEA could be effectively eluted by the metal ions through ion-exchange reaction. The results are valuable for choosing an efficient eluent and controlling the environmental pollution caused by the release of IEA.
