摘要:
It is well known that mercury is the only metal which can be pre-concentration by gas phase amalgamation on a suitable noble metal such as Au,Au-Pt alloy wire, and subsequently determination by AAS and AFS. By using this technique, which only required a simple accessory, the detection limit of an analytical method can be greatly improved simply by increasing the sampling volume. Unfortunately, this enrichment technique could only be applied to Hg so far.
