Abstract:
Residual formaldehyde(FA)in environmental water samples,certain aquatic products,vegetables,and other food items poses a severe threat to environmental safety and human health.Therefore,the rapid,sensitive and selective detection of FA is very essential for food safety and environmental protection.In this work,a new 1,8-naphthalimide-based fluorescent probe NIPh for FA detection was synthesized by using hydrazide group as a reactive site for FA and naphthalimide as a fluorophore.Based on the photoinduced electron transfer(PET)process,the prepared probe NIPh showed a remarkable fluorescence lighting-up response towards FA in aqueous medium with high selectivity,fast response(within 4 min)and a low limit of detection(0.16 μmol/L).Further,the probe NIPh was also successfully applied as optical probe to detection of FA in cabbage,enoki mushroom,pond and tap water samples,with recoveries over 96%,and relative standard deviations less than 4%,demonstrating tremendous potential in FA monitoring in the field of food industry and environment.
