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 In order to study the micro-chemical analysis of complex niobate tantalate single mineral, we determined that the medium containing 8% hydrochloric acid and 2% oxalic acid is the sample solution. In order to make effective use of trace samples, BPHA (N-benzoylbenzene) and PMBP (1-phenyl-3-methyl 4-benzoylpyrazolone-5) Reasonable extraction system makes niobium, tantalum, zirconium, titanium, iron, tungsten, thorium, uranium, rare earth elements, lead, aluminum, calcium, magnesium, manganese and other 14 elements
