Soil flushing Colloidal gas aphron suspensions generated from a plant-based surfactant

摘要

Natural surfactant solutions obtained from the fruit pericarps of Sapindus mukorossi, com- monly known as Ritha or soapnut, are tested for their ability to remove hydrophobic organic compounds (HOCs) from soil. Colloidal gas aphron (CGA) suspensions generated using the surfactant are used in this study to flush an HOC from a representative soil. Soil. Soil is spiked with a chlorinated hydrocarbon, hexachlorobenzene (HCB), serving as a model HOC representative of contamination at a super fund site north of Baton Rouge, LA.
