摘要
采用铜试剂-氯仿分离重金属元素铁、铜、铅等,并以PMBP(1-苯基-3-甲基-4-苯酰基吡唑酮)偶氮胂Ⅲ萃取光度法测定稀土总量。通过样品、标准物的测定,得到了较好的结果。
The consecutive determination of the rare earth elements in tea was studied by spectrophotometry. The sample digestion was made by incineration. The result was satisfactory by determination of the sample and primary standard tea.
