摘　　要：本实验研究国标法测定饲料总砷中,氢化物原子荧光法中酸介质和硫脲溶液对测定结果的影响。研究结果表明,试样稀释液中酸含量对结果影响较大,应在20%左右;稀释液中硫脲溶液含量对结果无影响。The method for determination of the total arsenic in feed by hydride generation-atomic fluorescence （HGAFS） was based on principle of GB/T 13079-2006.The effects of medium concentration of acids and thiocarbamide were investigated.The results showed that acids had important effect on determination result,the optimun content of acids was 20 %.
