摘　　要：针对复杂铌钽酸盐单矿物微量化学分析研究,本文确定以8N盐酸—2%草酸为试样溶液的稳定介质。为了有效地利用微量试样,选用BPHA(N—苯甲酰苯胲)和PMBP(1—苯基—3—甲基4—苯甲酰吡唑酮—5)为二个组试剂,建立一个合理萃取系统,使铌、钽、锆、钛、铁、钨、钍、铀、希土元素、铅、铝、钙、镁,锰等14个元素得到分离和测定。Sample solution contained 5 mg of nlobotantalate mineral can be separated in the medium of 6 N-HC1-2%H_(2)C_(2)0_(4) solution on the account of the two reagents of BPHA and PMBP separately added to the system of extraction.The procedue can be used to determine 14 elements such as Nb,Ta,Zr,Ti,Fe,W,Th,U,RE,Pb,Al,Ca,Mg and Mn.The sample taken only 20-30 mg for complete analysis.
