Facile synthesis of low-cost MnPO4 with hollow grape-like clusters for rapid removal uranium from wastewater

Direct reduction of diluted CO2 gas to C2 products by copper hydroxyphosphate microrods

“…While the two satellite peaks at 942.0 and 962.5 eV indicate that copper is present as Cu 2+ in this material. 31 In the XPS spectrum of P 2p (Figure 1E), the peaks at 132.6 and 133.7 eV correspond to P 5+ in PO 4 3À , 32 which verifies the presence of PO 4 3À . The O 1s spectrum (Figure 1F) can be fitted to three peaks at 530.18, 531.18, and 532.08 eV, 33 which correspond to the binding bond energy of metal oxygen, hydroxyl group (OH), 34 and P-O bond, 35,36 respectively.…”

Smartphone-assisted colorimetric determination of uranyl ions in aqueous solutions

“…1 With the rapid development of nuclear weapons and the nuclear industry under the public spotlight, public concerns about uranium mining and environmental management have become increasingly pressing. [2][3][4] Any link from uranium mining to the disposal of the radioactive wastewater may result in the unavoidable release of uranium into the environment, 5,6 which is susceptible to flow across regions with the change in the water environment surrounding uranium mines, 7 leading to the distribution of uranium in soil and water. 8,9 Uranyl ions (UO 2 2+ ) are the most stable and prevalent form of uranium that can be found in the environment.…”

Adsorptive removal of uranium(vi) from wastewater using a crosslinked amidoxime-functionalized β-cyclodextrin polymer

“…Due to simple operation, high efficiency, low cost and so on, 9,10 adsorption is widely used in uranium separation and recovery. 11 Saleh et al developed a polyethyleneimine modified activated carbon/Fe (PAF) as an effective magnetic adsorbent to remove U(VI) ions, which was costeffective, easy to prepare and environmentally friendly. 3 It is well known that sorbents play the central part in the whole adsorption process, [12][13][14] and thus it is quite important to design and search for efficient adsorbents for removing U(VI) from water to safeguard the ecological environment and longterm development of mankind.…”
