摘要: In the research conducted complexation of Cu/sup 2 +/ by an Armadale Horizons Bh fulvic acid sample was studied to facilitate program. The use literature-based stability constants for ion complexes species formed with different sites deduced from design experimental program led a capability predicting binding macro quantities Cu(II) Horizon as function degree neutralization, ionic strength, and metal concentration. predictive quality provided such assignment parameters is felt provide strong corroborative support site assignments thus model itself. 10 references, 6 figures, 5 tables.
