SOLUTE BREAKTHROUGH CURVES FOR PROCESSED KAOLIN AT LOW FLOW RATES

The primary aim of this study is to assess the significance of diffusive migration on the transport of simple NaCl salt solution through a homogeneous compacted clay soil at relatively low flow rates. Solute breakthrough curves for a 0.01-M NaCl solution permeated through kaolin soil in laboratory column tests are evaluated at two flow rates. Based on testing, diffusion dominates miscible transport at the low flow rates common in fine-grained barrier materials. Also, the effluent electrical conductance values measured immediately after sampling reflect the dominance of diffusion on the solute migration process.
