提出了一种测定水中低浓度孔雀石绿绿色和结晶紫的简便方法。从1000 ml的水样中的染料进行预浓缩，磁性固相萃取使用磁性亲和吸附剂（磁铁矿固定铜酞菁染料）。由于吸附剂的磁性，也可以在含有悬浮固体的水样中进行预浓缩过程。在洗脱捕获的染料后，通过荧光光度法检测洗脱液中染料的存在。在0.5-1.0 mug l（-1）水的范围内，可以重复检测到这两种线索的浓度。这些染料不仅可以在饮用水中检测到，也可以在河流中检测到。(C)2001爱思唯尔科技有限公司版权所有。
A simple procedure for the detection of low concentrations of malachite green and crystal violet in wa ter is presented. The dyes were preconcentrated from 1000 ml of water samples with magnetic solid phase extraction using magnetic affinity adsorbent (magnetite with immobilized copper phthalocyanine dye). Due to the magnetic properties of the adsorbent the preconcentration process can also be performed in water samples containing suspended solids, After elution of the captured dyes, their presence in eluates was detected spectrophotometrically. Concentrations of both clues in the range 0.5-1.0 mug l(-1) of water could be reproducibly detected. The dyes can be detected not only in potable water, but also in river ones.
