腐植酸(包括黑腐酸HA和黄腐酸FA)广泛存在于自然界[1-4].各种不同来源的腐植酸在结构上基本相似,反映在它们的物化性质与生物活性方面也大致相同.一般认为这种结构尚不太清楚的大分子有机化合物往往同各种金属离子结合起螯合剂的功效.对金属在环境中的积聚、迁移和固定起着十分重要的作用[5-7].近年来利用各种现代的方法与仪器来研究腐植酸与金属离子的作用机理及其反应物结构的报道很多,但研究结果很不一致,结论也不统一[8-13].

The X-ray photoelectron spectra of complexes formed between fulvic acid (one of the most widely distributed natural geopolymers on the earth's surface) and Zn(Ⅱ),Cd (Ⅱ),Hg (Ⅱ),Cu (Ⅱ),Ag (Ⅱ), Pb (Ⅱ),La (Ⅲ) and Pr (Ⅲ) were studied by using SHIMADZU ESCA 650B X-ray photoelectron spectrometer with Mga1,3, X-ray (Ex=1253.6 eV) as the excitation radiation.Samples were stuck on doublesided adhesive tapes and C18 of the adhesive component was taken as reference standard.for the calibration of binding energy (285.0 eV).
