| 摘 要： | 采用不同原子吸收光谱法对不同钙含量饲料中的铅含量进行测定,试验了不同钙量对铅测定结果的影响,比较了不同测定方法的测定结果,考察了不同时间添加硫酸盐对测定结果的影响。结果表明,饲料中的钙含量对铅的测定结果有较大影响,不同测定方法结果差异较大,且硫酸盐的存在会对测定结果造成一定干扰。

| Abstract: | Different atomic absorption spectrometry had been used in determination of lead in feeds. The impact of calcium dose on determination of lead was studied. We compared the results of different determination methods, investigated the effect of sulfate adding time on the lead determination. The results showed that the calcium content of feed affacted the lead determination results significantly. There are quite different results in different measurement methods and the presence of sulfate had interference on the determination results. |
