自胡武弟等制备了P_(507)萃取树脂,用它在色谱柱上分离稀土化合物以来,已有不少报道,但用气相色谱法分离稀土螯合物却至今未见报道。本文作者曾用一种新型β-二酮类螯合剂——三氟乙酰基特戊酰基甲烷(TPM)对稀土螯合物做过气相色谱分离,因吸附、置换等原因,其色谱峰常出现 P 507 extraction resin has been prepared from Hu et al. Since it was used in the separation of rare earth compounds on the column, there have been many reports, but the rare earth chelates have not been reported by gas chromatography. The authors used a new type of β-diketone chelator - trifluoroacetyl pivaloylmethane (TPM) on the rare earth chelates have been gas chromatographic separation, due to adsorption, replacement and other reasons, the chromatographic peaks often appear
