摘要： 通过比较多种防锡变色剂的防变色效果,发现乙二胺四甲叉膦酸(EDTMP)是一种优良的防锡变色剂。用XPS、AES及Raman光谱探讨了EDTMP的防变色机理,结果表明EDTMP在锡表面形成了一种耐蚀性保护膜。在深度剖析曲线的元素组成近似恒定区测得膜的相对原子浓度(A.C.%)为:O 48.0%;Sn 10.7%;N 7.7%;C 23.1%;P 10.5%。

Abstract: It is found by accelerating tarnish test of cysteine solution that ethylenediamine tetra-methylene phosphoric acid(EDTMP)was an excellent antitarnishing agent for tinplate. The antitarnish mechanism of EDTMP for tinplate has been studied by XPS, AES and laser Raman spectromety. A complicated anticorrosion film was formed on tin surface. The relative atomic percent contents(A. C. %)or the film obtained from the constant element comosition region of the profile curves were O 48.0%,Sn 10.7%, N 7.7%,C 23.1% and P 10.5.

Key words: XPS, AES, antitarnish film, tin
