Abstract

This paper presents the design, fabrication, and assembly of a new geo-environmental engineering apparatus specifically made to experimentally evaluate the viability, feasibility, practicality, and economics of electrokinetic extraction of conservative and reactive contaminants from fine-grained soils and to develop a better understanding of the various complex transport processes, electrochemical reactions, and physicochemical soil-contaminant interactions during the process. The design criteria and details of each component of the new apparatus are presented. The distinct advantages of the apparatus developed are discussed. Typical experimental results obtained by the apparatus are presented to demonstrate its simplicity of operation and versatility of measuring various parameters at different spatial and temporal intervals.

Keywords:
electrokinetics, soil remediation, experimental apparatus, laboratory studies, fine-grained soil, soil-contaminant interactions, electrochemical reactions
