| Abstract: | A method for the determination of mercury in drinking water by the intermittent flow hydride generation atomic fluorescence spectrometry was described.Optimum working conditions of the instrument were studied,including current of hollow cathode lamp,flow rate of carrier gas,concentration of potassium tetrahydroborate solution,acidity of sample solution.Under the optimum condition,the detection limit was 0.02ng/mL.The method has been applied to the determination of mercury in drinking water.The recovery determined via adding standard was in the range of 96.2 %～102 %.The relative standard deviation was 2.3 %.The method was simple,rapid sensitive and accurate. |
