| Abstract: | The direct determination of arsenic by graphite-furnace atomic absorption spectrometry is critically examined. Matrix stabilization by nickel salts is effective for preventing charring losses of arsenic, but cannot eliminate strong interferences. Direct analysis of environmental and biological samples is impossible because of the presence of aluminium, sodium, potassium and sulphates. |
