Photochemical treatment of a mixed PAH/surfactant solution for surfactant recovery and reuse

Abstract

Beca use of their hydr oph obic natur e, polycycl ic aromatic hydrocarbons (PAHs resentative PAHs and lithium perf l u o ro o c t a n e s u l f o n a t e (LiFOS) as a PFS. Direct photolysis (UV only) and UV/H2O2 p rocess enhanced the PAH degradation in LiFOS solutions

Mathematical evaluation of activated carbon adsorption for surfactant recovery in a soil washing process

“…Therefore, surfactant solution after washing should be separated from contaminants and reused. Current approaches to recovering and reusing surfactant include ultra-filtration [10,11], precipitation [12], foam fractionation [13], solvent extraction [14], photochemical treatment [15,16], and selective adsorption by activated carbon [17].…”
