Abstract

Applying AAS method, especially with the help of cold vapor system MVU-1A and hydride vapor generator HVG-1 to analyze heavy metals considered as pollutants in waste water has practical and scientific meaning. Accurate and reliable data can be achieved by using modern AA 6501S instrument. Detection limits of each element given by this method are always lower than the maximum allowable concentration of pollutants. In this topic, metals such as Hg, As, Cu, Pb, Zn, Fe will be analyzed and taken into consideration as a part of environmental research. Tham Luong Canal - a large industrial zone in the North-West of HCM City - and wells nearby are places where samples are taken and studied.
