Descloizite mineral originated from Grootfontein, South West Africa, is used in the present work. The chemical analysis of this mineral reveals the presence of V(2)O(5)=20.94 wt%, CuO=0.45 wt%, FeO in traces. An EPR study of sample confirms the presence of VO(II) and Fe(III). Optical absorption spectrum of descloizite indicates that VO(II) is present in distorted octahedral environment. NIR results are due to water fundamentals.
本研究使用了源自西南非洲格鲁特丰坦的水钒铜矿。对该矿物的化学分析表明，其含有V₂O₅ = 20.94 wt%、CuO = 0.45 wt%，FeO含量微量。对样品的电子顺磁共振研究证实了VO(II)和Fe(III)的存在。水钒铜矿的光吸收光谱表明VO(II)存在于畸变八面体环境中。近红外结果归因于水的基频。
