采用动态界面张力法研究了5-辛氧基甲基-8-羟基喹啉（Hocqn）与Ni（II）在庚烷-水界面上的络合动力学。界面张力的降低是由于在界面处形成1：1络合物的吸附所致。结果表明，在界面处的络合速率比在本体中快43倍，并且该速率还依赖于水相中的抗衡阴离子。
Complexation kinetics of 5-octyloxymethyl-8-quinolinol (Hocqn) with Ni(II) at the heptane-water interface was studied by measuring the dynamic interfacial tension. Decrease in the interfacial tension was caused by the adsorption of 1:1 complex formed at the interface. It was found that the complexation rate at the interface was 43 times faster than that in the bulk, and that the rate also depended on the counter-anion in the aqueous phase.
