Abstract
AbstractIn this study, fiber‐polymer composite films were prepared by adding 0.5 g, 1.0 g, and 1.5 g of modal/cotton (50 : 50) waste to 10 % PVA film, and the properties of the films were revealed by SEM, FTIR analyzes and swelling percentage. It is observed that the strength of the bonds in the FTIR analysis decreases when modal/cotton fibers are added to the PVA film. While a 406 % swelling is achieved in the PVA film, the swelling percentages of the films decrease when modal/cotton fibers are added to the PVA film, and a greater swelling is observed at pH 9 compared to pH 5. The adsorption efficiency of tetracycline and diclofenac sodium on the films was researched at different pH levels and film doses. Tetracycline removal reached its highest value at pH 9, while diclofenac sodium removal reached its highest value at pH 5. Langmuir and Freundlich isotherm models were determined for tetracycline and diclofenac sodium adsorption. Tetracycline removal is better described by the Freundlich isotherm model, whereas diclofenac sodium removal fits the Langmuir isotherm model better. As a result, films prepared with modal/cotton waste not only provide tetracycline and diclofenac sodium removal but also contribute to waste recycling by utilizing waste fiber materials.
