An inner filter effect based Schiff base chemosensor for recognition of Cr(<scp>vi</scp>) and ascorbic acid in water matrices

Abstract

An effective and simple fluorescent sensing approach for recognition of Cr(<sc>vi</sc>) using a Schiff base chemosensor,<italic>N</italic>′-[(<italic>E</italic>)-(3,4-dimethoxyphenyl) methylidene] furan-2-carbohydrazide, was developed.
