A selective and rapid spectrophotometric method for the determination of acetylcholine has been developed by flow injection technique coupled with ion pair extraction using tetrabromophenolphthalein ethyl ester dichloroethane solution, where selectivity can be improved by using both higher pH(pH 11) on extraction and thermochromism of ion associates in a flow system.
