摘要：

A flow injection system incorporating a microcolumn of sulfhydryl cotton fibre was combined with inductively coupled plasma mass spectrometry for the on-line preconcentration and determination of gold in natural waters. Use of a sampling time of 10 min (40 ml) and an eluent (KCN) volume of 250 mu l resulted in a nominal preconcentration factor of 160. The limit of detection was 0.19 ng l(-1) and the precision was 3.6% at the 5 ng l(-1) level. Application to the determination of gold in natural waters was demonstrated.
