摘要
采用混合酸V（HNO3）＋V（HClO4）=5＋1对新鲜蕉柑的陈皮和果肉样品进行湿法消化处理，并用分光光度法测定了陈皮和果肉中铜的含量。该法的回收率为96．9％～100．8％，相对标准偏差在0．28％～3．94％之间，方法简便、快速、准确。
Mter digested with fresh samples the mixed acid V（HNO3） ＋ V（HClO4） = 5 ＋ 1 was used, the content of copper in Chenpi and pulp was determined by spectrophtotometry. The recovery of this method was 96.9% ～ 100.8%, and the coefficient of variation was 0.28% ～ 3.94%, the method is simple, rapidly and accurate. The result provides the theoretical basis for guiding people reasonably to eat the Chenpi and pulp.
