Abstract
A simple method is described for the digestion of biological material containing mercury. The procedure is based on complete volatilization of mercury and subsequent absorption in an aqueous solution of potassium permanganate and sulphuric acid. Mercury ions are determined with dithizone using the reversion method. The statistical treatment of the calibration line shows that the proposed method is sufficiently sensitive and precise for toxicological work.Opisana je jednostavna metoda za mineralizaciju biološkog materijala, koji sadržava živu. Postupak se osniva na isparivanju žive i apsorpciji isparene žive u vodenoj otopini kalijum permanganata i sumporne kiseline. Nakon mineralizacije živini ioni se određuju pomoću ditizona (reverziona metoda). Statistička obrada baždarnog pravca pokazuje, da je predložena metoda dovoljno osjetljiva i precizna za toksikološki rad
