【摘要】 为了提高植物生长调节物质1-萘甲氧基乙酸溶液的润湿性和渗透性,将其与SDS(十二烷基硫酸钠)等表面活性剂进行了复配.采用表面张力法测定了复配体系的表面张力.实验表明,1-萘甲氧基乙酸复配体系的表面张力显著降低.其中,SDS与DTAB(十二烷基三甲基溴化铵)摩尔比为1∶1体系的增效作用最佳;SDS与OP—10(聚乙二醇辛基苯基醚)摩尔比为5∶1加KC l体系的增效作用也较佳.其CγM C分别为23.7 mN/m和28.2 mN/m,低于多种植物叶片的临界表面张力值.更多还原

【Abstract】 In order to improve wettability and permeability of 1-naphthyl methoxy acetic acid aqueous solution（regulative substance of plant growth）,which was mixed with SDS and other surfactants.The surface activities of SDS and its complex systems in 1-naphthyl methoxy acetic acid aqueous solution were determined by measuring the surface tension.The results showed that the surface tension of mixed system decreased.The synergism of mixed system of SDS and DTAB（1∶1 mole） showed a maximum and the mixture of SDS—OP-10（5∶1 mole） and KCl has synergism.Their γ_CMC values were 23.7 mN/m and 28.2mN/m,respectively.The γ_CMC values were lower than the critical surface tension needed by many plant leaves.更多还原
