Data Related to the Oxidation of m-Phenylenediamine

This dataset was created to support research on the "Effect of m-Phenylenediamine Oxidation on Polyamide Membranes and Its Application in Lithium Ion Concentration from Salt Lakes." It records structural characterization data, interfacial polymerization process parameters, and separation performance test results of TFC-FO membranes prepared with different oxidation times. The dataset includes multi-dimensional experimental data such as membrane surface chemical structure (ATR-FTIR, XPS), micro-morphology (SEM, AFM), hydrophilicity (contact angle), permeability performance (water flux, reverse salt flux), and lithium ion concentration performance (recovery rate, concentration factor).

The data is stored in tables and images, and all of it comes from repeated experiments under controlled lab conditions. It can be used for membrane material screening, performance prediction model training, and optimization of lithium extraction from salt lakes.
