It is very difficult to eliminate these influence factors completely by conventional treatment. Surface properties and surface treatment of ultrafine red phosphorus and MMT and their interface properties with polymer matrices were studied in this thesis. The results were characterized by GC, FTIR, XRD, DTA, TG, XPS, UV, SEM, TEM and other physical and chemical methods. The main contents are as following: 1. The study of factors influencing ultrafine red phosphorus's invariability and phosphine liberation indicated red phosphorus undergone oxidation and dismutation reaction in air, and trace ion of iron, copper and nickel fastened water absorption and oxidation, in which the effect of copper ion was the most, while aluminium and zinc ion could slow down red phosphorus'oxidation, and silver ion had the best effect on red phosphorus moisture absorption. Inhibitors such as aluminium hydroxide, magnesium hydroxide, organic phenol and ferrous potassuim cyanide had a good effect on reducing red phosphorus moisture absorption and restraining phosphine liberation.

本文围绕纳微米材料的表面处理及其在高聚物基体中的应用这一主题，系统地研究了超细红磷和蒙脱土两种常见材料的表面特性、表面处理方法及其与高聚物基体的界面特性，通过气相色谱、红外光谱、X射线衍射、差热、热重、X射线光电子能谱仪、紫外光谱、扫描电镜、透射电镜等现代分析仪器以及其它物理、化学方法对实验结果进行了表征和分析，全文主要内容如下： 1、对影响超细红磷安定性的因素以及磷化氢的缓释研究表明：红磷在空气中发生缓慢氧化、歧化反应，微量的铜、铁、镍等金属离子增加了它的吸水和氧化速度，其中铜离子的作用最为明显，而铝、锌等离子减慢了红磷的氧化速度，银离子对减少红磷的吸湿性效果最好。

Vulcanization thing in sulphur natural gas, take off to exclude, Make organic sulfur content and the vulcanization hydrogen of the natural gas of raw material accord with relevant technical index requirement , satisfy production needs,Today of the chemical swift development of natural gas the desulphurization method of natural gas also emerge endlessly , In traditional a ethanol amine the foundation of wet desulphurization and the dry law desulphurization of zinc oxide on, have arisen the desulphurization of normal temperature of ferric oxide, the dry law desulphurization of activated carbon and member sift desulphurization, DDS biochemical wet desulphurization wait for new technology .

硫的存在造成合成氨工艺中催化剂中毒，因此需将含硫天然气中的硫化氢、有机硫等硫化物脱除，使产品天然气的硫化氢和有机硫含量符合有关技术指标要求，满足生产需要。在天然气化工迅猛发展的今天，天然气脱硫方法也层出不穷。在传统一已醇胺湿法脱硫，氧化锌干法脱硫的基础上，出现了常温氧化铁脱硫，活性炭干法脱硫，分子筛脱硫，DDS生化湿法脱硫等新技术。

The photocatalytic degradation property of ZnM2O4 (M=Cr, Mn, Fe) nanoparticles was investigated by using methyl orange, acid red B and reactive red K-2G as model pollutants under the irradiation of a mercury-vapor lamp (λ＞400 nm) or sunlight. The degradation rates of the above three dyes by ZnM2O4(M=Cr, Mn, Fe) are over 80％, 57％ and 39％, respectively within 2 h. It is found that ZnM2O4 (M=Cr, Mn, Fe)has a novel photocatalytic behavior for dyes under visible light irradiation.
