摘要: As copper (Cu) stable isotopes emerge as a tool for tracing Cu biogeochemical cycling, an understanding of how fractionate during complexation with soluble organic ligands in natural waters and soil solutions is required. A Donnan dialysis technique was employed to assess the isotopic fractionation synthetic ethylenediaminetetraacetic acid (EDTA), nitrilotriacetic (NTA), iminodiacetic (IDA) desferrioxamine B (DFOB), well Suwannee River fulvic (SRFA). The results indicated enrichment heavy isotope (65Cu) complexes, Δ65Cucomplex-free values ranging from +0.14 +0.84‰. strong linear correlation found between logarithms stability constants complexes magnitudes fractionation. These show that by can affect signature free ion. This considered most bioavailable species, h...
