This standard specifies the use of bromophenol blue Spectrophotometric method, spectrophotometry for the determination of triethylamine in surface water and aerospace industry wastewater. The determination range is 0.5 to 3.5 mg/L of water samples, and the sample above 3.5 mg/L can be determined after diluting. This method reacts triethylamine with bromophenol blue in alkaline medium to form a yellow compound and performs spectrophotometric determination at 410 nm. This method is suitable for water quality monitoring and the detection of industrial wastewater.
