Development of Solid-Phase Extraction Porous Sheets Containing Polymer Brush Capable of High-Rate Adsorption and Easy Combustibility

十八烷基氨基基团引入的聚合物链接枝到多孔片材上，用酸性萃取剂浸渍。浸提液浸渍的多孔盘填充的筒被发现是适用于在多元素溶液中的痕量镧系元素的预浓缩，然后通过电感耦合等离子体质谱法测量。

An octadecylamino-group-introduced polymer chain grafted onto a porous sheet was impregnated with an acidic extractant. The extractant-impregnated porous-disk-packed cartridge was found to be applicable to the preconcentration of trace amounts of lanthanides in a multielement solution prior to their measurement by inductively coupled plasma mass spectrometry.
