This paper presents studies on the maturity, composition, texture and origin of the organic matter from the basaltic copper ores in this area by using methods such as measurements of their reflectance, elemental analysis, infrared absorption spectra and C-isotope composition. 本文通过反射率测定、元素分析、红外光谱和碳同位素组成测定等方法对该区玄武岩铜矿有机质的成熟度、组成、结构及成因进行了研究。
The molecular structures of title compound and the intermediate 3-amino-4-amnioximinofurazan ( AAOF ) were identified by IR, MS, 'H NMR, 13C NMR, elemental analysis and ultra-violet absorption spectrometry. 用IR、MS、1HNMR、13cNMR、元素分析和紫外线吸收光谱法对标题化合物及其中间体&3-氨基-4-氨基肟基呋咱进行了分子结构表征。
The complexes have been isolated chromatographically and characterized by elemental analysis, electron absorption spectra, infrared spectra and1H NMR spectroscopy. 诸配合物通过层析色谱柱分离,并用元素分析、电子光谱、红外和1H核磁共振所表征。
( 4 ) In elemental adsorption and competition absorption, adsorptions of heavy metal with temperature, pH, and ionic strength were similar. 单质吸附与竞争吸附中,重金属吸附随温度、pH、离子强度的影响变化趋势相似。
The structures of the coordinated polymers were verified with infrared ray spectrometry, ultraviolet spectrometry and elemental analysis. It was found that the corresponding absorption peak of the coordinated polymer showed an obvious red shift. 通过红外、紫外等分析手段发现在配合物中相应吸收峰出现一定程度的红移,结合元素分析验证了配合物的结构。
