Manganese estuarine water

A graphite furnace procedure has been described [674] for the direct determination of iron, chromium, and manganese in seawater and estuarine waters in which the interference normally associated with the presence of sodium chloride is eliminated. The technique requires only very small sample volumes (10-20 il) for the atomisation stage. The reproducility of the method was very good. Sensitivities of 0.4,0.2, and 0.07 xg/l and precisions of determination of 4.5,3, and 11% (at 2 xg/l level) were obtained for iron, manganese, and zinc. 

Beck et al. [61] used flow injection magnetic sector ICP-MS to determine cadmium, copper, nickel, zinc, and manganese in estuarine waters. The online preconcentration system used Toyopearl A-T Chelate 650 H as chelating resin, and was validated for an alkaline water standard reference material (SLEW-2).
