钼的高灵敏显色反应及其应用

本文提出了钼的高灵敏显色反应[Mo（Ⅵ）－SCN－Morin－BPR－Twwen80体系]和在测定微量钼的应用。研究了Mo（Ⅵ）、SCN、桑色素（Morin）、溴邻苯三酚红（BPR）和吐温80（Tween80）显色配位体系的特性，该体系的最大吸收峰为565nm，最佳酸度为0．10～0．35mol／LH2SO4介质中，摩尔吸光系数ε＝3．5×106L·mol(-1)·cm(-1)，在565nm波长处空白值最低。配合物的组成比为Mo（Ⅵ）：SCN：Morin－BPR－1：6：3（在Tween80存在下）。0～2．50μgMo(6 )／50mL范围内，服从郎伯－比尔定律。回收率为98％～102％。应用此法测定土壤和头发中微量钼，获得满意的结果。

Effect of Thickness on the Structure and Tribological Properties of MoSx Coating

MoSx coatings were prepared by bipolar-pulse DC unbalanced magnetron-sputtering system with the variation of coating thickness at different Ar pressures.The composition and surface morphology were determined by using energy dispersive X-ray and scanning electron microscopy;the structural characterization was analyzed by X-ray diffraction.The friction and wear properties were investigated by fretting tests in air with less than 10% and 50% relative humidity.At 0.40 Pa pressure,(002) basal plane orientation was formed throughout the coatings.At 0.88 Pa and 1.60 Pa pressures,(002) basal plane orientation was only noticed in the first stage of coating growth(around 0.20 μm in thickness), and then edge orientations with their basal planes perpendicular to the surface would be evolved in the coatings.Humidity has a minor influence on the coatings that have(002) basal plane orientation,whereas the tribological properties of MoSx coatings with edge orientations are greatly affected by humidity.The mechanisms of coating growth and friction and wear processes are discussed.
