本文以石蜡作溶剂,讨论了固相萃取方法。并以1-苯基-3-甲基-4-苯甲酰基代吡唑酮[5](PMBP)为萃取剂,模拟样品为氟碳铈矿和独居石矿(采用低浓度),在pH>6.2时,萃取率>95%。大多数阳离子及无机酸根不被萃取,该法可用于分析测定。
In this paper, paraffin as a solvent, the solid-phase extraction method is discussed. The simulated samples were bastnaesite and monazite (using low concentration) with 1-phenyl-3-methyl-4-benzoylpyrazolone [5] (PMBP) > 6.2, the extraction rate> 95%. Most of the cation and inorganic acid radicals are not extracted, the method can be used for analytical determination.
