A dataset of a continuous kinetics adsorption raw data using a continuous measurement of adsorption platform

The raw data was obtained from the modified photometric software window of the spectrophotometer, providing absorbance values. Subsequently, the remaining concentration in the solution was calculated based on the absorbance values, and the adsorption concentration was determined by subtracting the remaining concentration from the initial concentration. The fitting of the data involved applying the introduced liquid film diffusion kinetic equation to analyze the data, thereby obtaining the adsorption weighting factors and diffusion rates of ions diffusing from the solution into the liquid film and from the liquid film into the particle interior in the liquid film diffusion model proposed in this study.

原始数据采集自经过改造的分光光度计（spectrophotometer）的光度软件窗口，可提供吸光度（absorbance）数值。随后基于该吸光度数值计算溶液中的剩余浓度，再通过初始浓度减去剩余浓度得到吸附浓度。本研究提出的液膜扩散模型（liquid film diffusion model）中，数据拟合环节采用本文引入的液膜扩散动力学方程（liquid film diffusion kinetic equation）开展数据分析，最终得到离子从溶液扩散至液膜、以及从液膜扩散至颗粒内部过程的吸附权重因子与扩散速率。
