✦ Synopsis


A systematic study was made of mterferences of As(V), BI(III), Se(N), SMIIJ), Sn(IV) and Te(IV) m the determmatton of As(V), Sb(III), Se(N) and S&V) by hydride-generatlon atonuc absorption spectrometry The mterfenng elements were apphed m concentrations between 1 ng ml-' and 100 pg ml-' The effect of potassmm mdtde on the interferences by bismuth, selemum and tellunum on the antunony absorption slgnal and the Interferences of antunony, arsenic, bismuth, tellunum and tm on the selemum absorption slgnal by addltlon of oxygen and a mxture of oxygen and ozone were also mvestlgated A time versus absorption diagram wtth superlmposed recordings of the absorption signals of the elements antimony, arsemc, bismuth, selenmm, tellurmm and tm IS given

A procedure suitable for routine analysis of arsenic in orange juice using instrumentation available in most control laboratories was developed. Organic matter is destroyed by the dry ashing technique, the ash is dissolved in \(\mathrm{HCl}\), and hydrides of arsenic are generated by the addition of

The use of hydride generation techniques for arsenic species is pH dependent. Identical responses can not be obtained from arsenite, arsenate, monomethylarsonic acid @MAA) and dimethylarsinic acid (DMAA) when the same acid concentration is used. Thus some methods commonly used for the direct determi
