| Abstract: | This work studies the preparation of modified carbon paste electrode and suggests a new anodic stripping voltammetry for the determination of trace mercury by the modified carbon paste electrode. The modified electrode has much higher sensitivity to mercury determination than a carbon paste electrode. There is a good linear relationship between peak height and Hg concentration in the range of 20 ×10-9 - 10 ×10-6g/ml with the detection limit of 5×10-9g/ml. The method has good selectivity and satisfactory results have been obtained in determination of mercury in water samples. |
