Manufacturing method of metal salt of 2,5-dihydroxyterephthalic acid and detetion sensor for acid gas using the same

摘要

The present invention is a method for producing a 2,5-dihydroxyterephthalic acid metal salt capable of selectively detecting hydrogen gas and producing a chemical sensor that can be easily detected at room temperature through fluorescence change, and acidic acid using the same. It relates to a gas detection sensor.
