摘要：
This study presents a time-efficient method of analysing 210Pb, 210Bi, and 210Po in natural waters. The optimum pH (1.00), temperature (95 °C), and time (4.5 h) for simultaneous auto-deposition of 210Bi and 210Po onto Ni discs were determined and thermodynamically and kinetically clarified. Under the optimum conditions, the determination of 210Pb, 210Bi, and 210Po in natural seawater, lake water, and rainwater can be finished within 2 months. The preliminary results in in situ water samples validated our protocol, with favourable recoveries for all three nuclides, and revealed the potential application of the 210Bi–210Pb pair to trace particle cycling in seawater.
