石英晶体微天平（QCM）被用来测量原位结合的铅（II）离子的花生酸（ArH）的朗缪尔单层在空气-水界面。将水平取向的QCM降低到ArH单层上，并将Pb 2+溶液的analiquot注入单层下方。观察到QCM频率降低，与Pb 2+结合到ArH单层一致。考虑了脂肪酸与二价金属离子比率（F：M）为2和1的模型。实验数据与2：1结合一致。
A quartz crystal microbalance (QCM) was used to measure the in situ binding of lead (II) ions to a Langmuir monolayer of arachidic acid (ArH) at the air-water interface. A horizontally oriented QCM was lowered onto an ArH monolayer and an analiquot of a Pb2+solution was injected beneath the monolayer. A decrease in the QCM frequency was observed, consistent with Pb2+binding to the ArH monolayer. Models for a fatty acid to divalent metal ion ratio (F:M) of 2 and 1 were considered. The experimental data was consistent with 2:1 binding.
