摘要:

This paper describes a method of direct determination of serum Ni by controlled- temperature graphite furnace of AA. Ammonium oxalate is used as a matrix modifier to eliminate interferences caused by chlorides of alkali and alkaline earth in sample. The operating procedure has been applied to determine Ni contents of serum from 190 adults in Hefei district of China and good results have been obtained.
