| 英文摘要 | the interference effects of major matrix elements, contained in gold ores (silicate-, oxide-, sulfide-, bismuth- and tellurium-ores) for the determination of gold by electrothermal atomic absorption spectrometry (etaas), were studied. samples of five one-component (cu, mo, ni, pd and v) and 12 two-component chemical modifiers composed from above five one-component modifiers were compared for their anti-interference effects on the major matrix elements (al, as, bi, ca, cu, fe, mg, mn, pb, sb, te and zn) in gold ores. a chemical-modifier solution composed of 1000 mg l(-1) each of ni and v showed the best performance. gold in five decoppered copper oxide ores was determined by etaas with the help of the ni/v chemical modifier without matrix pre-separation. the relative standard deviation was 3.9% (n=9) for 0.47 mg l(-1) gold. the recoveries of added gold (50 mg l(-1)) were 93-102%. the characteristic mass was 12.8 pg.
