Experimental dataset for boron removal in membrane capacitive deionization under multi-ion conditions

This dataset contains raw experimental measurements and time-series data for boron removal using membrane capacitive deionization (MCDI) under multi-component ionic conditions. The dataset includes repeated ion concentration measurements, system characteristics, conductivity, pH, and temporal evolution of MCDI performance. All derived results, including removal efficiency, ion selectivity, and specific energy consumption (SEC), can be reproduced from these data. The dataset supports mechanistic analysis of charge-limited behavior and ionic competition in real groundwater systems.本数据集包含多组分离子条件下采用膜电容去离子（membrane capacitive deionization, MCDI）脱除硼元素的原始实验测量数据与时间序列数据。该数据集涵盖重复离子浓度测量结果、系统特性参数、电导率、pH值以及MCDI性能的时间演化过程数据。包括脱除效率、离子选择性与比能耗（specific energy consumption, SEC）在内的所有衍生结果均可通过本数据集复现。本数据集可支撑真实地下水系统中电荷限制行为与离子竞争过程的机理分析。
