平衡浓度

Distribution of an ionizable drug acro a membrane at equilibrium is determined by the drug's pKa （the pH at which concentratio of un-ionized and ionized forms of the drug are equal） and the pH gradient, when present.

In the sixth chapter, according to our nations situations, a probing study on the development and application of natural mordenite was carried out at the aim to develop a new adsorbent carrier and reduce the cost of adsorbent preparation. The characters of natural mordenite were chemically changed by an acid. The effects of the acid solution concentration, temperature, mordenite size and treatment times on the physico-chemical characters of mordenite were undertaken. The adsorption equilibrium of CO on the character-changed natural mordenite was measured.

The preparation of avermyctin emulsions in water was achieved by mixing the surfactants polyoxyethylene (10) octylphenyl ether (OP10), polyoxyethylene styrenated phenol ether (602), and polyoxyethylene (40) castor oil ether (EL-40) with polyoxyethylene (20) castor oil ether (EL-20), separatively. Emulsion stability was investigated by analyzing the hydrophile-lipophile balance, critical micelle concentration, and surface tension. Then, the surfactants of polyoxyethylene polyoxypropylene styrenated phenol ether (1601), block copolymer (L64), and octyl phenyl polyoxyethylene phosphonate were added to the emulsion made by blending EL-40 and EL-20, separatively. The stability of the emulsions was investigated further and discussed in terms of droplet size, surface tension, and zeta potential.

首先将辛基酚聚氧乙烯醚(OP10)、苯乙烯基酚聚氧乙烯醚(602)和蓖麻油聚氧乙烯(40)醚(EL-40)分别与蓖麻油聚氧乙烯(20)醚(EL-20)复配制备阿维菌素水乳剂，从亲水亲油平衡值、临界胶束浓度、表面张力等方面分析了二元表面活性剂复配对乳液稳定性的影响；其次，在EL-40与EL-20复配基础上，将苯乙烯基酚聚氧乙烯聚氧丙烯醚(1601)，嵌段共聚物(L64)和辛基酚聚氧乙烯醚磷酸酯分别添加到乳液中，从粒径、表面张力和zeta电势等方面考察三元表面活性剂复配对乳液稳定性的影响。

The axial dispersion coefficients and total mass transfer coefficients of xylose and sorbinose have been determined by stimulate response,technique with intert substance being traced.

实验结果表明，在低浓度下相平衡关系为线性；同时从时间域法处理实验数据的结果看出，随着流动相的流速加大，轴向扩散系数和时间总传质系数亦相应增

The adsorption isotherms for mixture of xylose and sorbinose on 732Ca〓 and 732Fe〓 ion exchange resins are measured. All the linear equilibrium relationships are obtained in the experimental condition. The adsorption selectivity of 732Fe〓 is preferred.

本文用静态法测定了木糖—山梨糖混合溶液在732Ca〓型和732Fe〓型树脂上的吸附平衡关系，结果表明，在实验浓度范围内，吸附等温线为线性，732Fe〓型树脂的吸附选择性优于732Ca〓型树脂。

Assuming chemical concentrations in water were relatively stable during sampling period, it is possible to estimate concentrations for most of chemicals with log K〓 larger than 3 by the measured concentrations in triolein.

根据平衡模式，SPMD技术、鱼样富集、沉积物吸附所得污染物浓度，三者之间应存在较好的相关关系。

Results showed that extraction abilities depends on the hydrophobic of solutes which pK〓 values are similar, e. g. acetic, propionic, butyric and valeric acids, while pK〓 values affect dominantly the extraction abilities of acids with similar hydrophobic, e. g. formic, acetic, chloroacetic, dichloroacetic, and trichloroacetic acids. Meanwhile, diluents and TOA concentration also affect the extraction equilibria of acids through the specific basicity of TOA .

TOA对酸性差别很小的一元羧酸如乙酸、丙酸、丁酸、戊酸的萃取能力主要取决于羧酸的疏水性参数logP；TOA对疏水性参数差别较小的羧酸如甲酸、乙酸、一氯乙酸、二氯乙酸、三氯乙酸的萃取能力主要取决于羧酸的电性参数；稀释剂的种类、TOA的浓度都会影响TOA的表观碱度pH〓，并通过TOA的表观碱度影响羧酸的萃取平衡。
