| 英文摘要 | The electrical conductivities (ECs) of suspensions containing 25 and 30 g kg(-1) solids prepared from the electrodialyzed clay fraction (< 2 mum in diameter) of latosol, yellow-brown soil, and black soil, dispersed in various nitrate solutions having concentrations of 1 x 10(-4)/z mol L-1, where z is the valence, and in distilled water, were measured at field strengths ranging from 14 kV cm(-1) to 210 kV cm(-1). On the basis of analyses of the charge density and exchangeable ion composition on the surfaces of soil particles in the suspensions, and of the characters of the EC-field strength curves of the various suspensions, it was inferred that the increment of EC (DeltaEC) and/or relative electrical conductivity (REC) can indicate the bonding strength between cations and soil particles. The bonding strengths of various cations with the soils diminished in the order: K+ > Zn2+ > Mg2+ = Ca2+ > Na+ for latosol, Ca2+ > Zn2+ > Mg2+ = K+ > Na+ for yellow-brown soil, and Zn2+ greater than or equal to Ca2+ greater than or equal to Mg2+ > K+ > Na+ for black soil. |
