Descrição: 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 the experiment several times to check the detection limit, quantification limit, and measurements of our testing methods. 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.
