Tannic acid (TA) as a natural plant polyphenol bearing multiple phenolic hydroxyl groups could cause considerable interactions with organic compounds. This work aims at detecting 8‐hydroxyquinoline (8‐HQ) based on poly (tannic acid) (PTA) by electropolymerization of TA on glassy carbon electrode (GC...
