Vo1.22No. 3 (Continued from page 109) 3.2.3 Analysis of real samples and standard addition recovery experiment the recovery rate experiment: in the selected chromatographic conditions, the experiment of Tongxiang City tap water and bottled purified water were spiked 5 lO ~ g / L, 2 repeated measurements, the recovery was between 94.5% ~ 108.4%, Table 4. The results showed Tongxiang water (see Figure 1) and bottled purified water content of bromate does not exceed the WHO and the EPA under the maximum allowable concentration, but bottled purified water 2 # (see Figure 2) there is still some cause cancer effect.
