| Abstract: | With microwave digestion and hydride generation-atomic fluorescence spectrometry(HG-AFS),the method of determining trace mercury species in seawater and surface sea mud samples in Fuqing city was developed.The method solved the problems in conventional digestion methods,such as massive use of reagents,complicated procedure,aptness to cross infection,etc.Meanwhile,the average recoveries for seawater and surface sea mud samples tested with adding standards were 94.4% and 93.3% respectively.The detection limit... |
