The goal of the proposed research is to develop a continuous non-invasive technique to evaluate the kinetics of film removal in the cleaning process. A study of the parameters influencing the removal of a film from a smooth surface (e.g., film thickness, viscosity and density) in conjunction with the solvent properties will provide insights into the mechanisms of contaminant removal. The results of this research will be used to test the validity of earlier kinetic cleaning studies. The extension of the proposed experimental methods to other cleaning geometries will aid in a fundamental understanding of the mechanisms of contaminant film removal from smooth surfaces. Total internal reflection fluorescent spectroscopy will be implemented to continuously monitor the removal of a contaminant film from the inner surface of a cleaning cell. Indirect measurement of rate of decontamination through continuously monitor the removal of a contaminant film from the inner surface of a cleaning cell. Indirect measurement of rate of decontamination through continuously monitor the removal of a contaminant film from the inner surface of a cleaning cell. Indirect measurement of rate of decontamination through continuously monitor the removal of a contaminant film from the inner surface of a cleaning cell. Indirect measurement of rate of decontamination through continuous measurement of contaminant species in the effluent from the cell during cleaning process and shear stress measurements will provide additional information about the kinetics of the cleaning process.

这项研究的目标是开发一种连续的非侵入性技术来评估清洗过程中薄膜去除的动力学。结合溶剂性质研究影响膜从光滑表面去除的参数(例如膜厚度、粘度和密度)将有助于深入了解污染物去除的机理。这项研究的结果将被用来检验早期动力学清洗研究的有效性。将所提出的实验方法推广到其他清洁几何形状，将有助于从根本上理解从光滑表面去除污染物膜的机理。全内反射荧光光谱仪将用于持续监测清洗单元内表面污染物膜的去除情况。通过持续监测清洗槽内表面污染物膜的去除情况，间接测量去污率。通过持续监测清洗槽内表面污染物膜的去除情况，间接测量去污率。通过持续监测清洗槽内表面污染物膜的去除情况，间接测量去污率。通过在清洗过程中连续测量单元流出物中的污染物种类来间接测量去污率，以及剪切应力测量，将提供关于清洗过程动力学的附加信息。
