As(Ⅲ) and As(Ⅴ) were analyzed in bamboo salts by hydride generation ICP-AES. In order to quantify the total amount of As in bamboo salts, AsH3 was producted by reacting with 6 mol/L hydrochloric acid and NaBH4, which was then analyzed by hydride generation ICP-AES. As(Ⅴ) was quantified simultaneously after selectively quantifying As(Ⅲ). As(Ⅲ) was quantified by determining the total amount of As and then correcting for the amount of As(Ⅲ). To improve the reliability of the analysis we repeated

According to the result of our quantification analysis of As existing in bamboo salt, the range of total As content was 0.05 mg/kg~0.2 mg/kg and As(Ⅴ) was over 90% of the total As.
