中文摘要：

anionic-nonionic 的效果在菲的举起上混合了表面活化剂(SDBS-TX100 ) ，由在一个水耕法的系统的毒麦的分核被学习，并且包括混合表面活化剂和混合物性质的作文和集中的影响因素也被讨论。结果证明有某些作文和集中的 SDBS-TX100 混合物能由毒麦提高菲和分核的举起，它能为菲和分核被归因于毒麦根的改进举起能力。SDBS-TX100 能与相应单个表面活化剂比较在大量表面活化剂集中(0 −0.8 mmol/L ) 由毒麦提高菲和分核的举起，并且在毒麦根的菲和分核的最大的内容在相应临界胶团浓度附近与 SDBS-TX100 的集中被获得。由毒麦的菲和分核的举起在有的 9:1 与 SDBS 的鼹鼠比率在混合表面活化剂答案，和 SDBS-TX100 混合与 SDBS 的增加的莫耳分率增加了到 TX100 在提高菲和分核的举起的最大的能力，在哪个没有表面活化剂，在毒麦根的菲和分核的相应最大的集中分别地是乘那些的 216 和 8.16 。从这研究的结果显示 anionic-nonionic 混合了表面活化剂(SDBS-TX100 ) 将是为到污染土壤的提高表面活化剂的植物救治技术的申请的一种比较喜欢的选择。

英文摘要：

The effect of anionic-nonionic mixed surfactant （SDBS-TX100） on the uptake of phenanthrene and pyrene by ryegrass in a hydroponic system was studied, and the influence factors including the compositions and concentrations of mixed surfactants and the compounds properties were also discussed. The results showed that SDBS-TX100 mixtures with certain compositions and concentrations could enhance the uptake of phenanthrene and pyrene by ryegrass, which could be attributed to the improved uptake capacity of ryegrass roots for phenanthrene and pyrene. SDBS-TX100 can enhance the uptake of phenanthrene and pyrene by ryegrass in a wider range of surfactant concentrations （0--0.8 mmol/L） in comparison with corresponding single surfactants, and the maximal contents of phenan- threne and pyrene in ryegrass roots were obtained with the concentrations of SDBS-TX100 around the corresponding critical micelle concentrations. The uptake of phenanthrene and pyrene by ryegrass increased with the increasing mole fraction of SDBS in mixed surfactant solutions, and SDBS-TX100 mixture with a mole ratio of SDBS to TX100 at 9：1 had the greatest capacity in enhancing the uptake of phenanthrene and pyrene, at which the corresponding maximal concentrations of phenanthrene and pyrene in ryegrass roots were 216 and 8.16 times those without surfactants, respectively. Results from this study indicate that the anionic-nonionic mixed surfactants （SDBS-TX100） would be a preferred selection for the application of surfactant-enhanced phytoremediation technology to contaminated soils.
