【Abstract】 The title method was developed,and some practical considerations in the design of on-line column preconcentration FIA system for FASS were studied.The relative standard deviation was about 1.3%(n=11)at a sampling frequency of 60h-1 with an enrichment of around 20 times.The advantages,such as high -efficiency,on-line,accuracy,precision,micro-amount of sample,automation et al,made it possible to be applied to the toutine analysis of natural waters.更多还原
