Abstract
The dataset presented in this study comprises the comprehensive experimental results obtained from the synthesis and characterization of MCOFs. This data forms the empirical foundation for all findings and conclusions discussed in this paper. It includes quantitative metrics such as yields, purity percentages, and final concentrations for each MCOF sample. Additionally, it contains raw and processed data points derived from the HPLC analysis, including retention times and peak areas, which serve as direct evidence for the separation and quantification of the compounds. The purpose of this dataset is to provide a complete and transparent record of the experimental work, enabling validation and future research. Under optimal conditions (pH 7, 100 mg adsorbent dosage, and 25-minute contact time), the MCOFs exhibited exceptional adsorption performance, with removal efficiencies of 90.0 % for DMP, 86.0 % for DBP, and 92.0 % for BPA. The developed analytical method achieved low detection limits (LODs) of 0.0058 mg/L for DMP, 0.0079 mg/L for DBP, and 0.0063 mg/L for BPA, indicating high sensitivity for trace-level contaminant detection in real water samples. Furthermore, the adsorbent demonstrated exceptional reusability, maintaining high performance after fifteen adsorption-desorption cycles, which is a significant improvement over conventional adsorbents.

Description of the data and file structure
# DATA FOR ADSORPTION OF BPA, DMP, AND DBP BY MCOFs
This dataset contains the experimental and analytical data supporting the paper recently accepted for publication, focusing on the adsorption of bisphenol A (BPA), dimethyl phthalate (DMP), and dibutyl phthalate (DBP) by magnetic covalent organic frameworks (MCOFs).
The data include calibration curves, optimized adsorption parameters, kinetic studies, reusability performance, limit of detection (LOD), limit of quantification (LOQ), and real wastewater treatment performance. These results collectively demonstrate the high selectivity, reusability, and efficiency of the synthesized MCOFs in removing endocrine-disrupting compounds from aqueous media.
Description of the data and file structure
The dataset is provided in a single Excel workbook titled “OFFICIAL MCOFs DATA FOR SUBMISSION.xlsx”, consisting of six main sheets:
1. CALIBRATION CURVES
Contains calibration data for BPA, DMP, and DBP standards used to quantify pollutant concentrations. Each curve includes concentration (mg/L), peak area, regression equations, and correlation coefficients (R²).
2. ANALYZED PARAMETER STUDY DATA
Includes experimental results for optimization studies such as adsorbent dosage, contact time, initial concentration, pH, and temperature. Each set represents triplicate average values with corresponding error data when applicable.
3. REUSABILITY
Provides adsorption–desorption cycle data to evaluate the stability and reusability of the MCOF adsorbent across multiple regeneration cycles.
4. KINETIC STUDY
Contains kinetic modeling data including pseudo-first-order, pseudo-second-order, and intraparticle diffusion model fitting parameters for BPA, DMP, and DBP adsorption.
5. REAL WATER SAMPLE ANALYSIS
Presents results from real wastewater treatment tests using effluent samples collected from plastic industry-affected river water. Includes pre- and post-treatment concentrations and removal efficiencies.
6. LOD AND LOQ
Lists the calculated limit of detection (LOD) and limit of quantification (LOQ) for each analyte derived from calibration data.

- None — all data were generated experimentally in this study.
The data for this study was meticulously collected and processed to ensure the accuracy and reproducibility of the results. Raw data was obtained through High-Performance Liquid Chromatography (HPLC) analysis, a technique employed to separate and quantify the individual components of the synthesized MCOFs. The specific parameters of the HPLC system were optimized for the chemical properties of the compounds under investigation, including solvent gradient, flow rate, and column temperature. Following the acquisition of the raw chromatographic data, all subsequent calculations and data processing were performed using Microsoft Excel. This included the determination of peak areas and retention times, which were then used to calculate yields, purity, and concentration of the MCOF samples. A series of standard calibration curves were generated within the Excel environment to ensure accurate quantification of the target analytes. Furthermore, statistical analyses and data visualization, such as the generation of graphs and charts, were also carried out in Excel to support the findings and conclusions presented in this paper.
