【摘要】 本文研究了用ＩＣＰ－ＡＥＳ法测定松香中的铁、铅、铜、锌、铝的方法，确定了松香中杂质元素同时测定的最佳工作条件，并对实际样品进行了ＡＡＳ法对比测定，回收率在９１％－１０４％之间，结果令人满意。该方法快速、简便、可靠，适用于出口松香的日常检验。更多还原

【Abstract】 A new method has been developed for simultaneous determination of 5 impurities (Fe,Pb,Cu,Zn,Al) in rosin by ICP AES. The satisfactory results of comparative test of real sample with AAS were obtained. The recovery rates are between 91% and 104%. This method is rapid and accurate. It can be applied to the determination of impurities in export rosin in daily inspection.更多还原
