ZK—4、NaANaHS3种沸石的铝化

用高温气－固相置换法对ZK－4、NaANaHS3种沸石进行铝化。组成分析、尾气分析、X射线衍射、晶体形貌分析、红外光谱和^29Si高分辨魔角固体核磁结果表明，3种低硅铝比沸石铝化后骨架可能存在Al-O-Al键。     

黄河水悬浮泥沙中金属含量的X射线荧光法测定

本文研究X射线荧光压片法测定黄河水悬浮泥沙中Cu、Zn、Ni、Mn、Fe、Zr、Sr、Rb、Ti元素的条件，并用峰背比法和非线性方法研究了样品稀释比与X射线强度间的线性关系。本法用GSD参考标样所建立的元素含量与X射线强度间的线性函数式线性良好，相关系数R值除Ti为0.98外，其余8种元素均在0.99以上，其余8种元素均在0.99以上。方法的可靠性用GSD参考标样检验，各元素测定结果的相对标准偏差均在3.6%以下。

Effect of Substrates on CuInSe2 Nanoparticle Thin Films by Radio Frequency Reactive Sputtering

CuInSe2(CIS) nanoparticle thin films have been prepared by radio frequency reactive magnetron sputtering from compound ternary fan-shaped targets on low-temperature substrates with pure argon gas as the atmosphere.The stoichiometry of the ternary compound semiconductor quantum dots can easily be controlled by the ratios of the ternary elements and sputtering parameters.CIS nanoparticle thin films regularly shaped and distributed reasonably uniform in size on substrates of 7059 glass etc can be grown in this way.The average particle diameter can be varied between 40-80 nm by an appropriate choice of the substrate temperature,power density and total CIS coverage.the optical and electrical properties of the CIS films have also been studied.     

降合物假冠醚研究（Ⅱ）新型聚合物的合成、吸附特性与绿色应用

合成了两种假冠醚型聚合物。研究了聚合物对金属离子的静态吸附性能。结果表明，聚合物对Ag^ ，Pb^2 ,Hg^2 表现出良好的吸附特性，且聚合物B的吸附能力优于聚合物A。吸附实验表明，除冠醚氧原子参与配位外，－CH2OH的氧原子亦参与了配位。聚合物B对Ag^ 的吸附过程中存在着明显的氧化还原现象，Ag^ 被还原为Ag^0，而聚合物分子中的－CH2OH被氧化成为－COOH。已初步将研究成果应用于本化学实验室的绿色化建设中。
