Abstract :H-point standard addition method insert ignore into journalissuearticles values(HPSAM); was applied to kinetic data for simultaneous determination of Niinsert ignore into journalissuearticles values(II); and Mninsert ignore into journalissuearticles values(II);. The method is based on the difference between rate of complexation of 1-insert ignore into journalissuearticles values(2-pyridylazo);-2- naphthol insert ignore into journalissuearticles values(PAN); with Niinsert ignore into journalissuearticles values(II); and Mninsert ignore into journalissuearticles values(II); at pH 7.5 in Triton X-100 micellar media. Niinsert ignore into journalissuearticles values(II); and Mninsert ignore into journalissuearticles values(II); can be determined simultaneously in the concentration range 0.084-0.734 and 0.055-0.366 8g mL -1 , respectively. The proposed method has successfully been applied for simultaneous determination of Niinsert ignore into journalissuearticles values(II); and Mninsert ignore into journalissuearticles values(II); in synthetic samples, spiked water samples, alloys and food products.   Key Words : Nickel; Manganese; Kinetic; HPSAM; PAN.
