摘　　要：采用干法灰化处理马来松香样品，用ICP—AES法测定了其中Fe、Al、Zn、Cu、Pb和Ni金属离子的含量。通过正交实验考察了ICP仪器工作参数，结果表明最佳测定条件为射频功率1．3kW，雾化器流量0．70L／min。试样提升量2．00mL／min，辅助气流量0．20L／min，等离子体流量15L／min。方法检出限为0．0002-0．008mg／L，回收率为93．60％～101．34％，相对标准偏差均小于4．45％。此法简便、快速、灵敏度高、准确性好、对环境污染小，可多元素同时测定。The contents of trace elements such as Fe, Al, Zn, Cu, Pb and Ni in the maleated rosin were determined by ICP-AES, and the sample was pretreated by the dry ashing method. The work parameters of the ICP instrument were obtained by orthogonal tests, and the optimal conditions obtained were as follows： RF power 1.3 kW,flow rate of atomizer 0. 70 L/min, sample uptake 2. 00 mL/min, flow rate of auxiliary gas 0.20 L/min, and plasma flow rate 15 L/min. The detection limits were 0. 000 2-0. 006 mg/L. the recoveryrates were 93. 60% - 101. 34%; and the precision was less than 4. 45%. This method is simple, rapid, accurate and producing less environment contamination, and many elements can be determined simultaneously.
