Abstract

The Batch-Injection Analysis (BIA) technique has been applied to the electroanalytical detection of the herbicide paraquat by square wave voltammetry (SWV) during sample injection. The results obtained showed that the herbicide can be detected at µg l-1 levels with small injection volumes (<100 µl). The time of each measurement was less than two seconds. The BIA method presents many advantages such as being extremely fast, with high reproducibility, good sensitivity and simple without pre-addition of or changing the supporting electrolyte.
