In early tests with the ligand 2-(2-Thiazolylazo)-p-cresol (TAC), we found that interference of the Fe(TAC) 1 complex may have competed with Fe(TAC) 2 for Fe. Also, i pmax was not reached in UV treated seawater after overnight equilibration ([TAC] = 40 Î¼ m, Î± Fe 3 + (TAC) 2 = 3.6 Ã 10 13).
BASE UNIT - kilogram (kg) - MASS. The standard for the kilogram is a cylinder of platinum-iridium alloy kept by the International Bureau of Weights and Measures in Paris. A duplicate at the National Bureau of Standards serves as the mass standard for the United States.
