Typical Soil

The distribution of Cd with depth, its particulate-bound speciation and availability index were studied in nine typical soil profiles of Saskatchewan, Canada. In the Ap horizons, Cd was predominantly in the metal-organic complex-bound form, accounting for about 38.8%, on average, of the total Cd present in the soils. The carbonate-bound Cd and the metal-organic complex-bound Cd accounted for 33.5 and 12.9%, respectively, on average, of the total Cd present in the B horizons. In the Ck horizons, Cd was predominantly in the carbonate-bound form, accounting for about 70.9%, on average, of the total Cd present in the soils. The M NH4Cl-extractable Cd of the soils, which is a measure of availability index of soil Cd, generally decreased with depth. Statistical treatment of the M NH4Cl-extractable Cd with different particulate-bound Cd species of various horizons in the soil profiles showed its highest correlation (P = 2.0 × 10−9, n = 42) with the amount of the metal-organic complex-bound Cd species, indicating the importance of the metal-organic complex-bound Cd species in Cd availability to the plants. Key words: Cadmium, soil profile, speciation, availability index, metal-organic complexes

Abstract A novel metal-organic complex formulated as [Cd (phen)(dipic) (H2O)2]. 3 H2O (phen = 1, 10-phenanthroline; dipic2−= pyridine-2,6-dicarboxylate) has been hydrothermally synthesized at 150°C for 48h. The structure of Cd complex was characterized by elemental analysis, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential thermal analysis (DTA), and single-crystal X-ray diffraction (SC-XRD). The crystal system of Cd complex is monoclinic with space group C 2/c. The pentagonal bipyramid (seven coordinate) around Cd2+ center filled by two terminal water ligands, one 1,10-phenanthroline, and one pyridine-2,6-dicarboxylate anion. Extensive O–H···O hydrogen bonding interactions involving all coordinated water molecules, dipicolinate oxygens, and crystallization water molecules further stabilize the complex units by linking them to form three-dimensional polymeric networks. Indeed, quantum mechanical studies were performed to understand effective factors on stability of the Cd(II) complex.
