摘要	Capture of trace amounts (parts per trillion or ppt level) of Sr-90 from highly Na+-rich (5 M or 115 000 parts per million) liquid wastes produced from reprocessing of spent nuclear fuel rods is crucial for continuous operation of nuclear power plants. However, no sorbents have shown such abilities. We now report that a novel layered vanadosilicate, SGU-7, with the unit cell parameters of a = 23.58 A, b = 30.04 A, c = 12.31 A, b = 100.28, and space group of P12(1)/a1, can effectively capture Sr-90 from a 5 M Na+ solution containing 6.2 ppt of Sr-90. It also effectively captures 1-ppb level Ra-226 from 2 M NaCl solution, and Cs+ and Sr2+ from groundwater, demonstrating that it can be immediately used to remedy groundwater and soil contaminated with Ra-226, Sr-90, and Cs-137.
