The deposited data were collected as part of the research project entitled ‘Wpływ złożonej modyfikacji fizykochemicznej środowiska glebowego na mobilność metali, metaloidów i herbicydów - badania laboratoryjne’, eng. ‘The impact of complex physicochemical modification of the soil environment on the mobility of metals, metalloids and herbicides - laboratory tests’, financed by the National Science Centre, Poland as part of the project under the OPUS 21 call (project no.: (2021/41/B/NZ9/03059).
The study aimed to develop and evaluate a poly(acrylamide-co-acrylonitrile) hydrogel (HG) for its sorption capacity toward various contaminants (metal ions - copper Cu, cadmium Cd; metalloid ions - arsenium As, selenium Se; herbicides - diuron D, glyphosphate G, and water-soluble polymers - anionic polyacrylamide AN, cationic polyacrylamide CT, and bacterial exopolysaccharide EPS) in mono- and bi-sorbate aqueous systems. The research investigated sorption mechanisms as a function of pH and ionic strength, interactions between different pollutants, the stability and reusability of the hydrogel, and the influence of water-soluble polymers on sorption. The study enabled a comparative assessment of the hydrogel’s effectiveness against different contaminants and identified systems in which its sorption performance is maximized, providing insights for environmental remediation.
The research was conducted in the period from 1st September 2024 till 1st March 2025 at the Institute of Agrophysics, Polish Academy of Sciences in Lublin. The collection contains the results of studies on the characteristic of hydrogel, adsorption/desorption capacity of the hydrogel and modified hydrogel by polymers towards to Cu, Cd, As, Se, D, and G in single and mixed system.
The attached files have been compressed to *.zip format. The dataset consists of the following files:
1) A_1 – „Characteristic” – the dataset contains raw experimental data used to determine physicochemical properties of the hydrogel. Numerical files (.xlsx) include swelling, surface area and porosity parameters, contact angle measurements, and zeta potential values as a function of pH. The dataset (.xlsx) also includes spectra from FTIR, XPS surface analysis, and thermogravimetric analysis. Image files (.tiff, .bmp) provide SEM micrographs and instrumental imaging used for morphological and structural evaluation.
2) A_2 – „Sorption” – the dataset contains raw measurements related to adsorption and desorption experiments performed on hydrogels and systems modified with water-soluble polymers, and all data are available in .xlsx format. The data concern kinetic studies, equilibrium adsorption, the effect of pH and ionic strength, sorption in bisorbate systems, and desorption using polymers, water and EDTA. The dataset also includes polymer adsorption measurements on the hydrogel, FTIR spectra and XPS surface analyses collected after sorption of heavy metals, metalloids, and herbicides, and zeta potential data recorded after polymer-material interaction.
The data was compiled on the basis of laboratory tests.
The results presented in file „A_1” were obtained using the following research equipment: sorptometer QuadraSorb (Quantachrome Instruments), goniometer (DSA100, Krüss), FTIR spectrometer ALPHA II (Bruker), XPS apparatus (Gammadata Scienta), STA 449 Jupiter F1 (Netzsch), QMS 403D A¨eolos (Netzsch), microscopy SEM Phenom ProX (Thermo Fisher Scientific), and Zetasizer 2000 (Malvern).
