A procedure for iron determination in quartz and silica glass materials based on adsorptive stripping voltammetry (AdSV) in the presence of catechol is described. Hanging mercury drop electrode as a working electrode was used. The optimized conditions include pH 7.1, accumulation potential ‐0.1 V, accumulation time 60 s, scan rate 10 mV s –1 , pulse amplitude 25 mV. In case of 60 s accumulation time the obtained detection limit was 2. 2 g L –1 Fe. The possibility of simultaneous determination of iron and copper in the same solution is shown. ET‐AAS technique was applied as a reference method to AdSV measurements.
