(A) Bi3+ concentration effect on peak height in a solution containing 200 mM NaCl, 10 μg·L−1 Pb2+ and Cd2+. Square wave anodic stripping voltammetry (SWASV) parameters: Ebegin = −1 V, Eend = −0.4 V, Estep = 0.010 V, Epulse = 0.02 V, Econdition = −0.4 V, Edeposition = −1 V, frequency = 50 Hz, deposition time = 300 s and equilibrium time = 20 s. (B) NaCl concentration effect on peak height in a solution containing 300 μg·L−1 Bi3+, 10 μg·L−1 Pb2+ and Cd2+. SWASV parameters: Ebegin = −1 V, Eend = −0.4 V, Estep = 0.010 V, Epulse = 0.02 V, Econdition = −0.4 V, Edeposition = −1 V, frequency = 50 Hz, deposition time = 300 s and equilibrium time = 20 s.
