The Simultaneous Voltammetric Determination of Aflatoxins В₁ and М₁ on a Glassy-Carbon Electrode

Figure 4

Dependences of the current derivatives of the aflatoxins В₁ and М₁ peak on the accumulation potential of the GCE. The background electrolyte is 0.1 М С₆Н₅О₇(NH₄)₃; τ_э = 30 s;  = 30 mV/s; (1)  = 2 × 10⁻³ mg/dm³; (2)  = 2 × 10⁻⁴ mg/dm³.
