味精中铅、锌测定国标法采用的是石墨炉原子吸收光谱法和原子吸收光谱法,不仅工作量大,费时,而且条件难以控制。该法控制PH=8.0,在100ml消解提取瓶中用双硫腙醋酸丁酯提取,然后用火焰原子吸收法同时测定铅和锌。实验结果表明:该法灵敏度高,1%吸收,0.0044A时铅为0.073ug/ml,锌为0.0044ug/m:线性好,回收满意,锌为96.4%—98.0%,铅为96,6%—103.0%。现将实验结果报告如 MSG in lead, zinc Determination of GB method using graphite furnace atomic absorption spectrometry and atomic absorption spectrometry, not only the workload, time-consuming, and the conditions are difficult to control. The method controls PH = 8.0, in 100ml digestion extraction flask with dithizone acetate butyl acetate extraction, and then flame atomic absorption spectrometry determination of lead and zinc. The experimental results show that the method has high sensitivity and 1% absorption. When 0.0044A, lead is 0.073ug / ml, zinc is 0.0044ug / m, linearity is good, recovery is satisfactory, zinc is 96.4% -98.0%, lead is 96.6% -103.0%. Now the experimental results reported
