结果表明,SDBS在蒙脱石上的损失主要由SDBS与钙离子间的沉淀作用导致,其沉淀的机理为蒙脱石中的钙离子被钠离子通过阳离子交换释放到溶液中,并与SDBS在溶液中产生沉淀.关键词:表面活性剂,蒙脱石,吸附0前言阴离子表面活性剂在土壤粘土矿物上的损失威胁着它们在有机污染土壤和地下水表面活性剂增效修复技术(surfactantenhanced...
Surfactant injection was presented as an alternative to promote liquid drainage in this study. To further understand the effect of surfactant on the flow characteristics of a gas–liquid flow, an experimental investigation of the flow pattern and pressure drop with and without surfactant was conducted...
Abstract:In order to explore the effect of component of surfactant on the copepod,we evaluated the acute toxicity of Sodium dodecyl benzene sulfonate(SDBS)and Sodium dodecyl sulfate(SDS)to the Pseudodiaptomus annandalei Sewell, which distributes widely in the seacoast and estuary.Results showed tha...

利用德国KRUSS公司生产的界面张力仪K11中的板法测定十二烷基苯磺酸钠在不同温度(5,10,20,30,35℃)和不同浓度下(100,400,800,1200,1600,2000 mg/L)的表面张力,确定有利于天然气水合物合成的最佳浓度为1 200 mg/L,这在工业应用中有着重要的参考价值,同时分析了表面活性剂加速天然气水合物生成的机理.关键词...
本人用SDBS与石墨粉混合球磨，也加了些水。抽滤的时候，SDBS由于其表面活性剂的作用，产物变得亲水得不...
The results showed that as an increase in gas flow rate at the same surfactant concentration the foaming time decreased while the liquid content of foam increased. On the other hand, increasing the surfactant concentration at a desired gas flow rate, the foam properties (both foamability and ...
