英文摘要	本工作研究了二元表面活性剂溶液的热力学,考虑了反离子对表面活性离子在表面相和胶团中的相互作用的影响,得出计算分子相互作用参数β_m和β_σ的将遍公式(β_m和β_σ分别代表胶团和吸附层中的分子相互作用参数):β_m=ln[((cmc_1)/(cmc_1~0x_(1m)))(c″_1/c′_1)~(K_1)]/x_2~2m=ln[((cmc_2)/(cmc_2~0x_(2m)))(c″_2/c′_2)~(K_2)]/x_1~2mβ_σ=ln[((c_1(π))/(c_1~0(π)x_(1σ)))(c″_1/c′_1)~(K_1)]/x_2~2σ=ln[((c_2(π))/(c_2~0(π)x_(...; The thermodynamics of the solution of binary mixture of surfactants has been studied. Considering the effect of counterion on the interactions between the surf ace active ions in the micelle and at the interface, the general equations for calculating the molecular interaction parameters in the micelle(beta )and at the interface (beta(sigma))have been obtained: beta = ln[cmc(1)/cmc(1)(0)x1 (c(1) /c(1))(K1)]/x(2)(2) = ln[cmc(2)/ cmc(2)(0)x(2) (c(2) /c(2) )(K2)]/x(1)(2) beta(sigma) = ln[cmc(1)/cmc(1)(0)x1(sigma)(c(1) /c(1))(K1)]/x(2)(sigma)(2) = ln[cmc(2)/ cmc(2)(0)x(2 sigma)(c(2) /c(2) )(K2)]/x(1)(sigma)(2) For the nonionic surfactants mixtures or the ionic ones in the presence of excess of inorganic electrolytes, as a limited case, the general equations reduce to beta = ln[cmc(1)/cmc(1)(0)x(1) ]x(2)(2) = ln[cmc(2)/cmc(2)(0)x(2) ]x(1)(2) beta sigma = ln[c(1)/c(1)(0)x(1 sigma)]/x(2)(sigma)(2) = ln[c(2)/c(2)(0)x(2 sigma)]/x(1)(sigma)(2) These equations have been applied to various systems of Watery ourfactant mixture, including cationic anionic, anionic-anionic and anionic-cationic mixed systems. The results indicate that (1)beta , and beta(sigma) for am cationic-anionic surfactant mixtures have very large negative values, demonstring the great molecular interactions between cationic and anionic surface active ions; (2)the "mutual phobicity" between fluoro carbon and hydrocarbon chains is clearly illustrated by the positive beta-values for the systems of the fluorocarbom and hydrocarbon anionic surfactant mixtures; (3) when the surface pressure is kept constant, in general, the beta-values are nearly constant, irrespective of the surface mole fractions; (4)the higher is the surface pressure, the greater the molecular interactions(the larger the vertical bar beta(sigma)vertical bar value) for the solutions of the same surfactant mole ratio(e.g.1:1 mixed solution).; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000207567800002&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 8; 02; 111-122; 1
