摘要 In the present method of trace elements wire has been developed work, a new preconcentration by adsorption onto a niobium for electrothermal atomization atomic absorption spectrometry （ETAAS） with a tungsten tube atomizer. Detection limits （pg. mL-1） by this method combined with ETAAS were 45 for bismuth, 7.0 for cadmium, 20 for copper, 1.3 for gold, 36 for lead, 65 for manganese, 9.5 for rhodium and 19 for silver.
