First, 30 principle in food by hydride generation-atomic fluorescence spectrophotometry may exist in different chemical forms of arsenic, including inorganic arsenic and organic arsenic. 6mol/L hydrochloric acid water conditions, inorganic arsenic in the form of chloride was extracted to achieve separation of inorganic arsenic and organic arsenic. Determination of total inorganic arsenic in the condition of 2mol/L hydrochloride. 31 reagent 31.1 hydrochloric acid solution (1+1): volume 250mL hydrochloric acid. Slowly pour in 250mL water, and mix. 31.2 the potassium hydroxide solution (2g/L): weighing 2G and potassium hydroxide dissolved in water, dilute to 1000mL. 31.3 potassium borohydride solution (7g/L): weighing 3.5G 500mL2g/L solution for potassium borohydride solution of potassium hydroxide. 31.4 potassium iodide (100g/L)-thiourea solution (50g/L): weighing Ki 10G, 5G water solution
