诸如Szyszkowski、Temkin、Frumkin、多项式和仿样函数那样各不相同的吸附等温线可以适用于LIX65N的实验界面张力等温线。在含溶剂化稀释剂的体系中,按照不同吸附等温线计算得到的各种表面过剩等温线是一致的。然而,在含非溶剂化稀释剂的体系中,按照Gibbs等温线和多项式计算得到的表面过剩等温线都有明显的最大值。显示最大值的那些函数可以用来进一步描述在有机相中的缔合度(3—1.5)。含Escaid100体系测定的吸附参数和表面过剩等温线的特性都与含甲苯体系中得到的相似。因此,基本上是脂肪族化合物的Escaid100在界面上却表现出芳香族化合物的特性。计算得到了表面过剩等温线,并将其用于预测LIX65N与铜进行界面反应的级数。形成稳定的2:1络合物的反应级数为1。吸附的1:1中间络合物与内层的羟基肟分子反应被认为是最慢的一步。预测的反应级数受羟基肟缔合作用的影响将仅是轻微的。
Adsorption isotherms, such as Szyszkowski, Temkin, Frumkin, polynomials, and spline functions, are all applicable to the experimental interfacial tension isotherm of LIX65N. In systems containing solvating diluents, the various surface isotherms that are calculated according to the different adsorption isotherms are consistent. However, in systems containing non-solvating diluents, the excess surface isotherms calculated according to the Gibbs isotherm and polynomial have significant maxima. Those functions that show the maximum value can be used to further describe the degree of association in the organic phase (3-1.5). The adsorption parameters measured by the system containing Escaid100 and the superficial isotherms are similar to those obtained in toluene-containing systems. Thus, Escaid 100, which is essentially an aliphatic compound, exhibits the aromatic character at the interface. The excess surface isotherms were calculated and used to predict the series of LIX65N interfacial reactions with copper. The reaction order to form a stable 2: 1 complex was 1. The reaction of the adsorbed 1: 1 intermediate complex with the hydroxyl oxime molecule in the inner layer is considered to be the slowest step. The predicted reaction order will only be mild with the effect of the oxime oxime association.
