| Abstract: | A method for determination of lead in leather and leather product by hydride generation-atomic absorption spectrometry with microwave digestion was developed.The condition of microwave digestion were optimized,and the influence factors such as concentration of NaBH4,acidity,the amount of K3Fe(CN)6 and interference of co-existing ion were investigated.The detection limit of this method was found to be 0.036 μg/L.The proposed method,when applied to analyze leather samples,gives recovery rates in the range of 96.8%-105.6%.The method is rapid,accurate and economical. |
