将引入十八烷基氨基的聚合物链接枝到多孔片材上，用双（2-乙基己基）磷酸氢盐（HDEHP）浸渍。将不同HDEHP浓度的HDEHP和乙醇的混合物用于浸渍。在乙醇蒸发之前，将引入了C18 H37 NH基团的多孔片浸入HDEHP/乙醇溶液中。装有在50（v/v）% HDEHP/乙醇溶液中制备的盘状HDEHP浸渍多孔片的药筒的液体渗透性是起始多孔盘填充药筒的液体渗透性的96%。HDEHP浸渍的多孔盘对钇离子的平衡结合容量为0.32摩尔/千克盘。此外，HDEHP浸渍的多孔盘包装盒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进行测量。
An octadecylamino-group-introduced polymer chain grafted onto a porous sheet was impregnated with bis(2-ethylhexyl)hydrogen phosphate (HDEHP). A mixture of HDEHP and ethanol of various HDEHP concentrations was used for the impregnation. The porous sheet into which a C18H37NH group was introduced was immersed in HDEHP/ethanol solution before ethanol evaporation. The liquid permeability of a cartridge charged with the HDEHP-impregnated porous sheet in disk form prepared in 50 (v/v)% HDEHP/ethanol solution was 96% that of the starting-porous-disk-packed cartridge. The equilibrium binding capacity of the HDEHP-impregnated porous disk for yttrium ions was 0.32 mol per kg of the disk. In addition, the HDEHP-impregnated-porous-disc-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.
