Lewis bases with lone-pair electrons were found to enhance the efficiency of chemical vapor generation (CVG) of gold with NaBH4 as the reductant. Such effect was tested by using ether, tetrahydrofuran, and triethylamine as the Lewis bases and a nondispersive atomic fluorescence spectrometer as detector. The results showed that the Lewis bases and DDTC gave similar enhancement effect for the CVG of gold. The detection limit and precision were found to be 1 μg/L and 8% (RSD), respectively. The results showed that Lewis bases with lone-pair electrons played an important role in the enhancement of the CVG efficiency of gold.
