用微波消解法与全消解法消解土壤标准样品，用石墨炉原子吸收光谱法测定消解液铅含量．比较两种消解方法的精密度和准确度。微波消解法的相对标准偏差为3．8％，全消解法为8．6％。与标准值的相对相差比较，微波消解法低于10％，电热板消解法高于19％。微波消解法的测出值均高于电热板消解法。
用微波消解法與全消解法消解土壤標準樣品，用石墨爐原子吸收光譜法測定消解液鉛含量．比較兩種消解方法的精密度和準確度。微波消解法的相對標準偏差為3．8％，全消解法為8．6％。與標準值的相對相差比較，微波消解法低于10％，電熱闆消解法高于19％。微波消解法的測齣值均高于電熱闆消解法。

The use of microwave digestion method and electric heating board digestion digestion soil standard sample, using graphite furnace atomic absorption spectrometric determination of lead content in solution, comparison of the two methods of precision and accuracy. Microwave digestion method the relative standard deviation was 291%-411%, electric heating plate method for 738 %- 1394 %. With the standard values of the relative difference comparison, microwave digestion method was lower than 5 %, higher than the 19 % electric heating plate method. Microwave digestion method for measured values were higher than the electric heating board digestion.
