| Abstract: | The signal characteristic and the factors
that affect the sensitivity of the flow injection derivative atomic absorption
spectrometry(FI-DFAAS) had been investigated in this paper. The base line stability,
sensitivity, precision and detecting limit had been compared between FI-FAAS and FI-DFAAS.
The results show that better precision, higher sensitivity and lower detection limit were
obtained with the FI-DFAAS . |
