英文摘要	The construction, performance characteristics, and application of a novel chromium(III) membrane sensor based on a new tridentates S,N,O Schiff's base 4-hydroxysalicylade-2-mercaptoanil (TSNO) are reported. The sensor was prepared by incorporating of TSNO, o-nitrophenyloctyl ether (NPOE), and sodium tetraphenylborate (NaTPB), into a plasticized poly(vinyl chloride) membrane. The sensor exhibits Nernstian response in the concentration range from 3.0 × 10-6 to 1.0 × 10-1 M with a detection limit of 1.5 x 10-6 M. It shows a very short response time (20 s). The electrode displays high selectivity towards chromium ion over several cations and can be used in a pH range 3.0-5.5. It was successfully applied to the determination of Cr(III) in wastewaters of chromium electroplating industries and as an indicator electrode in potentiometric titration of Cr(III) with EDTA and vice versa.
