摘要

吸附容量是吸附剂性能的一个重要指标，其评估通常需要对液相中的吸附剂浓度进行精确但复杂的测量。本研究提出了一种基于自制模型的比色传感方法，可通过吸附剂的吸光度直接评估有色阳离子的吸附容量。通过快速测定单阳离子（Co(II)、Ni(II)、Cu(II)和 U(VI)）体系、混合阳离子体系和实际废水样品中有色阳离子的吸附容量，证明了所提出的方法具有卓越的分析能力。此外，还开发了一系列比色卡，可快速有效地实时监测工业生产、资源提取、废水处理和其他应用中的吸附能力。这项研究有望极大地改进现有的吸附容量测量方法。

A colorimetric sensing method for direct determination of the adsorption capacity of colored cations in adsorbents

Adsorption capacity is a critical indicator of adsorbent performance, its assessment often requires precise but complicated measurements of adsorbate concentration in the liquid phase. This study presents a colorimetric sensing method based on a fabricated model for directly assessing the adsorption capacity of colored cations through the absorbance of the adsorbent. The exceptional analytical capability of the proposed method was demonstrated by the rapid determination of colored cation adsorption capacity in single-cation (Co(II), Ni(II), Cu(II), and U(VI)) systems, mixed-cation systems, and real wastewater samples. Additionally, a series of colorimetric cards have been developed to enable rapid and effective real-time monitoring of adsorption capacity in industrial production, resource extraction, wastewater treatment, and other applications. This research is expected to significantly enhance the methods available for adsorption capacity measurement.
