有二句话实在不会翻译了,请求各位帮忙了。? 讨论counter cation 其意思是反相阳离子、抗衡阳离子、对(阳)离子 本句主要说的是加入一种与被测离子形成离子缔合物(被测离子由亲水变成憎水从而可以沉淀或萃取出来)的对离子(此处可能是大分子量的有机阳离子) 因此第二句翻译为 if the counter cation is excessively hydrophobic, not only the analyte but also the free reagent added to convert the analyte into a collectable form is retained on the filter, sometimes rendering the collection by filtration time consuming。 如果对(阳)离子疏水性太强,不仅被测组分,而且没有反应(游离的)的对离子试剂(用于将被测组分转变成沉淀形式)也会留在滤纸上,有时会使过滤富集过程变得费时。查看更多
