含锡物料中各种组分的分析都要考虑锡的干扰问题,对于微量组分的分析,尚需采取予先富集的办法.锡的干扰主要有以下几种情况:由于锡盐极易水解,在近中性时生成的水解产物影响其他元素的测定;另外锡(Ⅱ)具强还原性,在氧化还原方法中产生干扰;锡离子对一些显色剂有反应,如不分离或掩蔽,则不可能得到正确的分析结果.含锡物料中微量杂质的测定,虽在某些情况下可采用加入掩蔽剂的办法消除锡的干扰,但往往由于加入掩蔽剂后使分析灵敏度降
Tin content of the various components of the analysis must consider the problem of tin interference, for the analysis of trace components, still need to take pre-enrichment approach. Tin interference mainly in the following situations: As tin salt extremely easy Hydrolyzate at near neutrality influences the determination of other elements. In addition, tin (II) has strong reducibility and causes interference in the redox method. Tin ions react to some color developing agents, such as not separating or masking , It is impossible to get the correct analysis results.Determination of trace impurities in tin-containing materials, although in some cases can be used to eliminate the interference of tin masking agent, but often due to the addition of masking agent to reduce the sensitivity of the analysis
