Dansyl Hydrazine Modified Cellulose as a Fluorescent Schiff Base for Selective Dual Sensing of 4-Nitroaniline and Cu(II) Ions
A sustainable and multifunctional fluorescent sensor based on a dansyl hydrazine-derived cellulose-modified Schiff base (DHCSB) was successfully designed and synthesized for the dual detection of 4-nitroaniline (4-NA) and Cu(II) ions in solution. Dialdehyde cellulose was first prepared and subsequently functionalized...
