A novel, highly sensitive, selective, reversible and turn-on chemi-sensor based on Schiff base for rapid detection of Cu(II)

A novel optical fluoro-chemisensor was designed and synthesized for copper (II) ions detection. The sensor film is created based on the embedded of N,N-Bis(2-hydroxo-5-bromobenzyl)ethylenediamine in poly-vinyl chloride (PVC) matrix. The optimal conditions of pH and response time at which higher efficiency of sensor film is performed were found to be 6.8 and 2.48 min respectively. This film shows high selectivity and ultra-sensitivity with low detection limit of 7.6 nM.211
