[Determination of chloroform and tetrachloro-methane in water with capillary column-microECD].
The method of determination of chloroform and tetrachloro-methane in water with capillary column-microECD had better and wider linear range and lower detection limit. At the range of 0-10 micrograms/L chloroform and 0-1 microgram/L tetrachloro-methane, the regression equation were calculated as Y = 1.959X + 4.816 (r = 0.9910) and Y = 3.947X + 42.58 (r = 0.9970). The lowest detection limit were 0.1032 microgram/L chloroform and 0.01219 microgram/L tetrachloro-methane. This method not only simplified the operating processes, but also increase the sensitivity, and reavled better precision and accuracy.
