Synthesis of A Biodegradable Polymer from Tyrosol, Fluorescein and Caprolactone for Sensing and Removal of Cupric Ions from Pond Water

Anthopogenic actions mostly contribute cupric ions to pond and other water bodies. These ions build rapidly in plants and animals, eventually entering the human food chain and causing public health problems. To address the health risks associated with these ions, a novel polymer molecule has been designed for sensing and removing them. This study entails creating a new polymer using tyrosol, fluorescein and caprolactone. This polymer has a strong selectivity for cupric ions, which causes a dramatic color shift for easy identification. It can detect even trace levels of copper ions in pond water. The hydrophobic properties of this polymer aid in the elimination of cupric ions, resulting in a yellow precipitate that precipitates toxic copper ions. This polymer is biodegradable, hence the process is environmentally beneficial. UV-Vis and EDAX spectra were used to evaluate the polymer's ability to remove ions from water. This invention provides a straightforward method to reduce cupric ion pollution, protect human health and address environmental difficulties.
