Study on adsorption behavior of octylphenol ethoxylates on silk fabric

研究辛基酚聚氧乙烯醚在丝织物上的吸附行为,包括吸附等温线、动力学和热力学,以及温度和第二组分烷基酚聚氧乙烯醚对吸附的影响,同时比较了辛基酚聚氧乙烯醚在五种织物上的吸附性能。结果表明,辛基酚聚氧乙烯醚在丝织物上的吸附等温线可用Langmuir-Freundlich方程、吸附动力学可用准二阶动力学方程分别描述。辛基酚聚氧乙烯醚在五种织物上的吸附能力由强到弱依次为:丝,棉,麻,涤纶,腈纶。

In this paper,the adsorption behavior of octylphenol ethoxylates on silk fabric including isotherm,kinetics and thermodynamics was studied. The influences of temperature and second component alkylphenol ethoxylates on adsorption were investigated. Moreover,the adsorption properties of octylphenol ethoxylates on five kinds of fabrics were compared. The results show that the adsorption isotherm of octylphenol ethoxylates on silk fabric could be well described by Langmuir-Freundlich equation,and the adsorption kinetics could be well described by quasi-secondorder kinetic equation. The adsorption properties of octylphenol ethoxylates on five kinds of fabrics are sorted in descending order as follows： silk,cotton,linen,PET,PAN.
