学科：环境科学 词目：非极性吸附 英文：nonpolar adsorption 释文：非极性吸附又称物理吸附（physicaladsorption）。是一种物理作用。这种作用的发生与胶体具有巨大的比表面和表面能有关。比表面指物体的裸露表面积与物体的质量之比值。比表面愈大。表面能就愈大，物理吸附作用也愈强。非极性吸附是从溶液中吸附物质的整个分子。
在某一极性介质中，游离的分散剂分子通过非极性尾链间的吸附作用被拉向那些已经吸附在颜料表面的分子。
In certain polar media, free molecules are drawn to those already attached to the pigment surface through apolar-apolar interaction of the tails.
该菌产生的毒素是一类极性较大的非蛋白类物质，活性碳能对其进行吸附； 该毒素能用甲醇将其从培养液中较好地提取出来。
The produced toxin, which could be adsorbed by activated charcoal and be fully extracted by methanol from its culture liquid, was not a kind of protein material.
此外，采用五种大孔吸附树脂富集纯化提取液中的赤芍总苷，实验结果表明，非极性树脂D101和ATD-21是性能良好的赤芍总苷吸附剂。
Also, the purification of TPG by macro adsorption resin was investigated. The results showed that nonpolar resin ATD-21 and D101 were good sorbents of TPG.
