摘要：

Copper ions in environmental water samples are collected and enriched quantitatively on a membrane filter made of cellulose nitrate as the complex with N,N-diethyldithiocarbamate. The collection seems to occur not only mechanically but also chemically. The complex together with the membrane filter is dissolved in an organic solvent such as N,N-dimethylformamide (DMF) and copper in this DMF solution is determined by graphite furnace atomic absorption spectrometry. Copper at ppb levels can be easily determined.
