Analisis Pergerakan Polutan Trikloroetilen Dalam Media Berpori Menggunakan Sentrifug Geoteknik (Analysis of Trichloroethylene Pollutant Migration in Porous Media Using Geotechnical Centrifuge)

摘要

Tricholoroethylene (TCE) is an organic solvent used in many industrial processes. TCE is one of Non-Aqueous Phase Liquid (NAPL) which has already contaminated soil and groundwater. The objectives of this study are to determine the migration of TCE in rhyolite and granite soil, to determine the migration of TCE in soil using 1 and 25 Gravity (G) force, and to determine the migration of TCE influencing factors in the soil. The characteristics of TCE migration in rhyolite and granite soil will migrate vertically and laterally to the bottom of the ground. The migration will be retarded in small particle size of soil. The fastest migration of TCE at 1G and 25G was found in the granite soil. The migration of TCE in dry soil is affected by properties of soil particularly particle size and cation exchange capacity.
