“…Recently, as an electrode material for a heavy metal sensor, a sensor made of Bi by an in situ method has been studied. 43 To compare this, the Bi/LIG electrode, which was fabricated in situ with Bi ions, was measured simultaneously for Cd, Pb, and Cu ions and compared with the measurement results of multiple heavy metal ions of AgNP/LIG electrodes. Heavy metal measurement of Bi/LIG electrodes was performed in situ by adding 600 μg L −1 Bi ions together with the heavy metal ions (Cd, Pb and Cu; concentration: 20, 40, 60, 80, 100, and 120 μg L −1 ) to be measured in 0.1 M acetate buffer.…”
