D Cao,

In this paper, 0.1 mol x L(-1) HCl, 6 mol x L(-1) HCl, pH 7.0 1 mol x L(-1) NH4Ac was oscillated and 6 mol x L-' HCI was boilled to extract and determine K, Na, Ca, Zn, Fe, Mn, Mg and Cu. Comparing with classical method that popularly used HNO3-HCl04 to degest and ash samples,the results indicated that for macroelement K,Na and Mg several extraction methods are similar to classical method,the recovery was 90%-115%,for microelement Zn, Mn and Fe could be extracted using pH7.0 1 mol x L(-1) NH4Ac, 0.1 mol x L(-1) HCI, 6 mol x L(1) HCI oscillating,the recovery was 100%-115%. Cu could be analysed using 6 mol x L(-1) HCI boiling. But the results of Ca were not better because of the enhancement effect. The results with ash sample were lower because many elements were lost when ash temperature was up to 450 degrees C. These methods of exatraction pretreatment are simple and rapid. The recovery and precision are satisfactory.
