The adsorptive behaviour of 16 elements in trace amounts as hydroxides and chelates of pyrrolidindithiocarbamidate of xylenol orange from aqueous solution on Amberlite XAD-4 resin was examined by using a short column.

• 本文采用短吸附柱(10×60mm,充填高度24mm)研究了非离子性吸附树脂AmberliteXAD-4从水溶液中对16种金属元素的氢氧化物,二硫代氨基甲酸衍生物的配合物和二甲酚橙配合物的吸附行为。
