Abstract


A procedure for the simultaneous determination of copper and zinc using molecularly imprinted polymer-modified sensor is developed. The linear range of copper and zinc was observed in the concentration window 0.098-23.80 µg L-1, with detection limits (S/N=3) as low as 0.0275 µg L-1 (zinc) and 0.0159 µg L-1 (copper).
