Boxes marine ecosystem

Box 6-1 describes a marine ecosystem in which NH3 is oxidized to NO2 (nitrite) and then to NOJ (nitrate). Ammonium ion in the top millimeter of sediment was measured with a microelectrode made by drawing a glass capillary tube to a fine point with an opening diameter of 1 p,m. Liquid ion exchanger drawn into the tip of the capillary serves as the ion-selective membrane in Figure lS-6. The natural antibiotic nonactin is used as the ligand L in Figure lS-6. It selectively binds... [Pg.342]
