发明名称 Surfactant-aided removal of organics
摘要 The present invention relates to a surfactant solution, and to using an aqueous solution of the surfactants, optionally with an antifoaming additive, for removing or washing MFAC contaminants from equipment, sludge, scale, and soil, among others. Examples of MFAC and related contaminants that can be removed by practicing the invention include at least a member of the tetraalkylleads, including but not limited too, tetramethyllead, trimethylethyllead, dimethyldiethyllead, methyltriethyllead, and tetraethyllead. While any suitable surfactant can be used for practicing the invention, an aqueous solution containing at least one member from the group of nonionic alcohol ethoxylates, including but not limited to the polyethoxylated aliphatic alcohols, is particularly effective at removing MFAC contaminants.
