17 11 2014 The emission lines of copper atoms Cu I zinc atoms Zn I and lead atoms Pb I which are elements of a brass alloy composition were used to investigate the parameters of the brass plasma The spectral profiles of Cu Zn and Pb lines have been used to extract more the electron temperature and density of the brass alloy plasma.
Thus Zn 2 Cd 2 Al 3 among others will not interfere In relatively dilute solutions the color of the ammonia complex may not be intense enough to give an unqualified identification and some other test for confirmation must be used Cu 2 forms a very insoluble reddish brown hexacyanoferrate II 2Cu 2 aq Fe CN 6 4 aq → Cu 2
The standard method postulated by DIN 38406 Part 16 describes the determination of Zn Cd Pb Cu Tl Ni and Co in drinking ground surface and precipitation rain water Because the presence of organic substances in the water samples can strongly interfere with the voltammetric determination a pretreatment with UV digestion using hydrogen peroxide is necessary.
