The results showed that the proper organic solvent and extractant were sulfonated kerosene and trialkyl phosphine oxide.

结果表明，较合适的溶剂和萃取剂分别为磺化煤油和三烷基氧膦。

Trioctyl phosphine oxide was used as the model of TRPO and its γ radiolysis was studied.

为了探讨三烷基氧化膦辐射乳化的原因及解决的办法，以三辛基氧化膦为TRPO的模型，对TOPO的γ辐解进行了研究。

A series of sulfonated poly(arylene thioether/ether phosphine oxide)s was prepared by direct polycondensation of sBFPPO and BFPPO with the diphenol-type or dimercapto-type monomers such as hydroquinone, bisphenol-A, 4,4'-biphenol, 4,4'-diphenol (6F), 1,5-dihydroxynaphthalene, 4,4'-dihydroxybiphenyl, and 4,4'-thiobisbenzenethiol, respectively.

将BFPPO与sBFPPO分别与多种二羟基或二巯基单体，如对苯二酚、双酚A、4，4'-二苯酚、双酚F、1，5'-二羟基萘、4， 4'-二羟基二苯硫醚和4，4'-二巯基二苯硫醚，直接共聚制备了一系列磺化聚芳醚三苯基氧膦，侧重考察了二羟基和二巯基单体结构单元对产物的耐氧化性能的影响。

The two rate equations fitted the experimental data well,as was confirmed by the reaction of bis(4-carboxyphenyl)phenyl phosphine oxide with ethylene glycol under constant reaction temperatures of 180197℃ and at different ratios of diol to diacid,whose rate constant and activation energy were calculated.

将这两个速率方程应用于双苯基氧化膦与乙二醇的恒温自催化聚酯化反应，计算值与实验数据相一致，并计算得到了该反应的速率常数和活化能。

The effects of the surfactants, trioctyl phosphine oxide, sodium dodecyl sulfonate and hexadecyl trimethyl ammonium bromide, on the extraction rate of Co^2^+ were investigated. The acceleration in the kinetics in contributed to the associated molecule~2 TOPO taking part in the extraction process directly. The decrement effects of SDS or CTMAB on the rate of extraction kinetics of Co^2^+ with HDEHP were also observed, which caused by the adsorption of molecules of SDS or CTMAB on the interface and decreased the interfacial adsorption amount of HDEHP. In addition, the extraction rate was reduced by a bigger margin in HDEHP-SDS system. This can be explained in terms of the formation of an electric field at the interface.

研究体系中加入不同表面活性剂所引起萃取速率的不同改变：三辛基氧化膦因与HDEHP形成可萃取的Co^2^+活性分子缔合物，降低了萃取过程活化能而使反应加速；十二烷基磺酸钠和十六烷基三甲基溴化铵因占据发生萃取反应的界面区，减小了HDEHP与Co^2^+反应的机会而使反应减速； SDS还因其在界面形成较强的负电场，造成Co^2^+的附加势能而使萃取速率有更大幅度的降低。
