Entiometric membrane sensor for determination of glutamate based on [4](1)(2,3-diazabuta-l,3- diene) ferrocenophane (IR)

Entiometric membrane sensor for determination of glutamate based on [4](1)(2,3-diazabuta-l,3- diene) ferrocenophane (IR)

A potentiometric membrane sensor has been developed and optimized based on [4](l)(2,3-diazabuta-l,3-diene)ferrocenophane as an ionophore for high selective determination of glutamate. The best performance was shown by a membrane with composition ratio of [4](l)(2,3-diazabuta-l,3-diene)ferrocenophane...
