摘要：

A cost effective reversible dual channel chemosensor (BT-1) has been synthesized for detection of Zn2+ ion based on a benzo[d]thiazole Schiff base. It exhibits high selective and sensitive optical changes in fluorescence intensity for zinc metal ions. Optical chemosensor (BT-1) exhibited fluorescence off-on effect with Zn2+ without any significant interference of other metal ions. The LOD of the optical chemosensors was calculated 0.11 mu M for Zn2+ ion. Probe BT-1 is applicable to electroanalytical recognition of Zn2+ metal ion with polyvinyl chloride membrane sensing response. Reported chemosensor was provided high sensing response in real environmental sample with quick response time.
