摘　　要：观察了ＴＢＰ的降解产物磷酸一丁酯（Ｈ_２ＭＢＰ）与锆在３０％ＴＢＰ－正十二烷／ＨＮＯ_３体系中产生界面污物的现象；研究了锆浓度、Ｈ_２ＭＢＰ浓度以及硝酸浓度对界面污物生成的影响，并对界面污物固体进行了红外光谱分析和Ｘ射线荧光分析。The behavior of H2MBP and Zr in forming interfacial crud is studied.The experiments show that interfacial crud can be formed by H2MBP and Zr in the system of 30%TBP-n-dodecane HNO3. The forming behavior depends on the concentrations of H2MBP,Zr and HNO3.The fil trated residue of the interfacial crud is analyzed using the techniques of IR spectra and X-ray fluo rescence and it shows that the residue is mainly composed of Zr(MBP)2.
