摘要
研究了有机改性膨润土对海水中柴油的吸附作用及其影响因素。结果表明,有机改性膨润土可以较好地吸附海水中的油,在温度为25℃、盐度33‰、振荡频率150r/min、pH为8的环境下,除油率可以达97%以上。该过程的吸附等温线符合Freundlich方程。
The adsorption of diesel oil in seawater with modification bentonite and the influencing factors were studied. The results indicate that the modification bentonite can adsorb the oil in the seawater fairly. Under the condition that the temperature is 25℃, salinity of seawater is 33‰, the stirring speed is 150 r/min, pH is about 8, the oil remove rate can reach over 97%. The adsorption isotherms can be described as Freundlich＇ s equation.
