Zusammenfassung: | One of the most effective oral antipyretics and analgesics, ibuprofen (IBP) is a primary ingredient in hospital wastewater because it is widely used to treat both acute and chronic pain. It is important to detect its concentration in the wastewater. Bio-electrochemical sensor is a promising detection method due to its durability and accuracy. Schiffbase is an advanced electrode materials for bio-electrochemical sensor. Which able to detect (IBP) concentration in wastewater.2,3dihydroxy-N'1-((E)-2-hydroxybenzylidene)-N'4-((Z)-2-hydroxybenzylidene (Schiffbase) materials have been synthesized and characterized.IR spectroscopy data identified (OH/H
