采用微波消解和ICP-OES测定了凤仙花和红花中重金属铜、铅、镍和稀土元素铈、钐、镧的含量。该方法的加标回收率为93.1%—103.8%,相对标准偏差(RSD)值不大于1.83%。实验结果表明,所测样品含量均未超过国家规定标准,适合入药。方法快速简便可靠。 The contents of copper, lead, nickel and rare earth elements cerium, samarium and lanthanum in impatiens and safflower were determined by microwave digestion and ICP-OES. The recovery of this method was 93.1% -103.8%, and the relative standard deviation (RSD) was less than 1.83%. The experimental results show that the measured content of the samples did not exceed the national standard, suitable for medicine. The method is fast, easy and reliable.
