The research project was undertaken to give the clues from which selective determination or speciation of trace metal species in biological and geological samples would be developed. The useful and hopeful results were obtained about the following items.1) Substoicheometric speciation for inorganic arsenic and organic arsenic and its application to seaweed samples. 2) Substoicheometric isotope dilution method for determination of strontium by solvent extraction with crown ether or cryptand, and its application to seaweed samples. 3) Substoicheometric isotope dilution method for determination of sulphur; sulphur was converted to methylen blue and then it was extracted with dodecyl sulphate. 4) Development of a new preconcentration method for neutron activation analysis; trace metals were extracted with diethyldithiocarbamate and collected in polystyrene foam. 5) Synergic extraction of lanthanide(III) with a beta-diketone and neutral bidentate ligand. 6) Evaluation of the reversed phase HPLC retention of metal-beta-diketonato complexes. 7) Reversed-phase HPLC separation of chlorophylls and metal-pheophorbide complexes. 8) Application of size exclusion chromatography/AAS method to fractional determination of vanadium and nickel species in crude oil. 9) High-performance thin-layer chromatographic separation of rare earth complexes with porphyrin.

开展该研究项目是为了提供线索，从中选择性测定或生物和地质样品中痕量金属物种的形态。本研究在以下几个方面取得了有益的结果：1）无机砷和有机砷的亚化学计量形态分析及其在海藻样品中的应用。2)冠醚或穴醚萃取亚化学计量同位素稀释法测定锶及其在海藻样品中的应用。3)亚化学计量同位素稀释法测定硫的研究将硫转化为亚甲基蓝，用十二烷基硫酸钠萃取。4)中子活化分析预富集新方法的研究用二乙基二硫代氨基甲酸盐萃取痕量金属，收集在聚苯乙烯泡沫塑料中。5)β-二酮和中性双齿配体对镧系元素的协同萃取。6)金属-β-二酮络合物的反相HPLC保留的评价。7)叶绿素和脱镁叶绿酸金属络合物的反相高效液相色谱分离。8)体积排阻色谱/原子吸收分光光度法测定原油中钒、镍形态9)稀土卟啉配合物的高效薄层色谱分离。
