Wat.r sol.bil.t. enhancement. of pyrene by bot. singl.-surfact.nt.and mixed-surfact.nt.sol.t.ons were compared and eval.at.d. t.e sol.bil.t. of pyrene in wat.r was great.y enhanced by each of t.it.n X-100 (t.100), t.it.n X-405 (t.405), Brij 35 and SDS, in which t.e wat.r sol.bil.t. enhancement. increased wit. increasing surfact.nt.concent.at.ons. t.e ext.nt.of sol.bil.t. enhancement. at.surfact.nt.concent.at.ons bel.w. t.e CMC is t.e order of t.100 > Brij 35 > t.405 > SDS; t.e sequence at.surfact.nt.concent.at.ons above t.e CMC is t.100 > Brij 35 > SDS > t.405. Pyrene was sol.bil.zed synergist.cal.y by anionic-nonionic mixed surfact.nt.sol.t.ons, especial.y at.l.w surfact.nt.concent.at.ons. t.e synergist.c power of t.e mixed surfact.nt. is SDS-t.405 > SDS-Brij 35 > SDS-t.100. t.e synergism as not.d is at.ribut.d t. increasing Kmc and/or decreasing t.e CMC of t.e mixed surfact.nt.sol.t.on. For SDS-t.405 and SDS-Brij 35 mixed surfact.nt.sol.t.ons, an increase in Kmc is coupl.d wit. a decrease in t.e CMC; for SDS-t.100, onl. a decreased in t.e CMC val.e is not.d. Mixed-surfact.nt.sol.t.ons may improve t.e performance of t.e surfact.nt.enhanced remediat.on (SER) of soil. by increasing t.e bioavail.bil.t. and biodegradat.on of non-aqueous-phase organic pol.ut.nt. and reducing t.e l.vel.of surfact.nt.pol.ut.on and remediat.on expenses.
