dc.description.abstract | This study provided direct observations on reaction kinetics of Cu and dissolved organic matter (DOM). Stopped-flow method and fluorescence technique were used to measure Cu(II)-DOM complexation over time. Suwannee River reference fulvic acid and water soluble soil organic matter were used as model DOM. Experimental conditions of pH 6, 5 × 10–5M Cu(II), and 5 mg C/L of DOM were used and the results were to simulate the relevant natural conditions. Both organic ligands reacted fairly rapidly with Cu(II). Reaction half-life of DOM was in the millisecond range. Two types of metal binding sites of organic ligands were identified. Fulvic acid yield forward rate constants: 1 × 106M-1s-1and 5.15 × 103M-1s-1, based on second-order reaction rate model. Water soluble soil organic matter gave forward rate constants: 1.34 × 105M-1s-1and 2.2 × 103M-1s1. From comparison of kinetic natures, the fast-reacting ligands were comparable to nitrilotriacetic acid (NTA) and slow-reacting ligands were more like salcylic acid. © 1994, Taylor & Francis Group, LLC.
