| Abstract: | A method for determination of mercury in copper concentrates by cold vapour atomic absorption spectrometry has been investigated in this paper. Copper concen trates were digested by HNO_3-HCl or H_2SO_4-KMnO_4(s) and the content of mercury was determined by mercury-measuring apparatus. RSD was less than 5%, and re covery was in the range 92-107%. |
