Celon, F. and Degetto, S. and Marangoni, G. and Sindellari, L. (1974) Microdeterminazione dell'arsenico in composti metallorganici con il metodo di Schöniger. Accademia Peloritana dei Pericolanti Classe FF.MM.NN., 54. pp. 57-62.
A method is described which allows the determination of arsenic in organometallic compounds following decomposition by the oxygen flask. Benzoyl peroxide is employed as a oxidizing aid in the combustion and also it prevents the formation of platinum-arsenic alioys. The combustion products are absorbed in a dilute iodine solution to ensure cornpìete oxi dation to As(V). The final determination of arsenic is performed by spec trophotometric determination of the arseno-molybdenum complex for med by treatrnent with an ammonium rnolybdate solution followed by reduetion with hydrazine sulphate. The proposed micro method is simple, rapid, and highiy reproducibile.
