Background
Meals components are broadly utilized in meals manufacturing for preservation, taste enhancement, and colour enchancment. Nevertheless, their in depth use has raised issues about potential accumulation within the atmosphere, significantly in water programs. Conventional strategies for detecting these components usually lack the sensitivity wanted for hint evaluation in advanced matrices like river water.
