Abstract

A Venturi-scrubber pre-concentration device used in conjunction with square wave anodic stripping voltammetry (SW-ASV) has been developed for simultaneous determination of heavy metals in contaminated airborne matter. The method was tested using various zinc, lead and cadmium mixtures. These were performed using contamination controlled air intakes. Successful analytical interpretation of the experimental results was achieved. Methods detection limits range from 1 ng/m³ for Cd(II) to 3 ng/m³ for Zn(II). The method was also applied to determination of lead and zinc in local ambient air (resulting in lead and zinc concentrations of about 10 ng/m³). The data was validated with conventional filter sampling analysis. The method offers in-situ capabilities of pre-concentration routines, and avoids most of procedural complexities, which are commonly found in similar applications.
