Abstract :Bismuthinsert ignore into journalissuearticles values(III); insert ignore into journalissuearticles values(0-25 m g/ml); is determined spectrophotometricaly at 513 nm after extraction into dichloromethane of the ion associate di-insert ignore into journalissuearticles values(hydrogenatedtallowalkyl);dimethylammonium tetraiodobismuthate. The reagent stream is distilled water, merged with 1.0 M sulfuric acid, 5% potassium iodide and 5% insert ignore into journalissuearticles values(w/v); ascorbic acid solution. The reagent stream is 0.2% insert ignore into journalissuearticles values(w/v); di-insert ignore into journalissuearticles values(hydrogenatedtallowalkyl);dimethylammonium chloride solution. The injection rate is 15 h-1. The calibration graph is linear up to 25 m g/ml. The detection limit is 0.35 m g/ml Bi. The system is applied on water samples and copper-based alloys.
