摘要：

The present work reports on an adsorptive stripping voltammetric procedure for the determination of tetramethrin. The best conditions found were pH 4 in 0.2 mol/L acetic acid/acetate buffer solution, an accumulation potential of -0.5 V (vs. Ag/AgCl electrode), an accumulation time of 60 s, frequency 120 Hz, step potential (E(s)) 2 mV. Under these conditions, determination limits of 1.7 ng/mL-1 (8.5 10(-9) M) are achieved.
