Xác định thủy ngân và Asen trong nước ngầm bằng phương pháp phân tích kích hoạt Nơtron

The preconcentration method of mercury and arsenic in the ground water samples by co-precipitation with PbS was developed. In the range of HCl concentrations from 0.1 - 0.6M and 10 mg of Pb as a collector in the sulphite form after adding 2% thioacetamide solution, the traces of mercury and arsenic were quantitatively separated from a large volume water sample (200 ml). This method has been applied for determination of mercury and arsenic traces in the ground water samples collected in Ho Chi Minh City by neutron activation analysis. The method is simple, rapid and reliable.
