min,以热水浸取熔融物,用IC-Na预处理柱分离铝、铁、钙、镁、锰等碱土和过渡金属阳离子,建立了碱熔-离子色谱法测定低品位萤石尾矿中氟化钙的方法。试验表明,经IC-Na预处理柱分离后,试液中铝、铁、钙、镁、锰等阳离子的质量浓度均低于0.1 μg/mL,因此这些元素对测定的干扰可忽略。实验表明,以氟离子质量浓度为横坐标,峰面积响应值为纵坐标绘制校准曲线,在氟离子质量浓度为1～30

g氢氧化钾-0.35 g硝酸钾为熔剂,于650 ℃熔融8 min,以热水浸取熔融物,用IC-Na预处理柱分离铝、铁、钙、镁、锰等碱土和过渡金属阳离子,建立了碱熔-离子色谱法测定低品位萤石尾矿中氟化钙的方法。试验表明,经IC-Na预处理柱分离后,试液中铝、铁、钙、镁、锰等阳离子的质量浓度均低于0.1 μg/mL,因此这些元素对测定的干扰可忽略。实验表明,以氟离子质量浓度为横坐标,峰面积响应值为纵坐标绘制校准曲线,在氟离子质量浓度为1～30 μg/mL范围内,校准曲线的线性相关系数为0.999 6。按照实验方法对2个萤石尾矿样品和1个萤石矿标准样品进行测定,并分别加入不同量的高品位萤石矿标准样品进行加标回收试验,加标回收率在96%～104%之间。将实验方法应用于测定低品位萤石尾矿样品和萤石矿标准样品中氟化钙,结果的相对标准偏差(RSD,<i>n</i>=7)为0.54%～1.5%,测定值与离子选择性电极法测定值或标准值相吻合。实验方法可用于测定低品位萤石尾矿中质量分数为5%～60%的氟化钙。","endNoteUrl_en":"http://yjfx.chinamet.cn/gyby/yjfx/EN/article/getTxtFile.do?fileType=EndNote&id=175336","reference":"[1]

low-grade fluorite tailings is of great significance for the evaluation and improvement of comprehensive recycling process.The semi-quantitative component analysis of low-grade fluorite tailings sample was first conducted by wavelength dispersion X-ray fluorescence spectrophotometer (WDXRF) and X-ray diffractometer (XRD). It was found that fluorine mainly existed in the form of calcium fluoride, and the sample mainly contained silicon, aluminum, iron, calcium, magnesium, potassium, sodium, sulfur and manganese. 4.0 g of potassium hydroxide and 0.35 g of potassium nitrate were used as flux. The sample was melted at 650 ℃ for 8 min and then leached with hot water. IC-Na pretreatment column was used to separate alkaline earth and transition metal cations such as aluminum, iron, calcium, magnesium and manganese. Thus, a method for determination of calcium fluoride in low-grade fluorite tailings was established by alkali fusion-ion chromatography. The results showed that the mass concentrations of cations such as aluminum, iron, calcium, magnesium and manganese in test solution were all lower than 0.1 μg/mL after separation with IC-Na pretreatment column. Therefore, the interference of these elements with the determination could be ignored. The calibration curve was drawn with the mass concentration of fluorine ion as <i>x</i>-axis and its corresponding peak area response as <i>y</i>-axis. The results indicated that its correlation coefficient was 0.999 6 with calcium fluoride in range of 1-30 μg/mL. Two fluorite tailings samples and one reference material of fluorite ore were determined according to the proposed method. Meanwhile, different amounts of high-grade fluorite ore certified reference material were added for recovery tests. The recoveries were between 96% and 104%. The proposed method was applied for determination of calcium fluoride in low-grade fluorite tailings samples and fluorite ore reference materials. The relative standard deviations (RSD, <i>n</i>=7) were between 0.54% and 1.5%. The results were consistent with those obtained by ion selective electrode method or the standard values. The proposed method was applicable for determination of calcium fluoride in low-grade fluorite tailings samples with mass fraction in range of 5%-60%.","bibtexUrl_en":"http://yjfx.chinamet.cn/gyby/yjfx/EN/article/getTxtFile.do?fileType=BibTeX&id=175336","abstractUrl_cn":"http://yjfx.chinamet.cn/gyby/yjfx/CN/10.13228/j.boyuan.issn1000-7571.012516","zuoZheCn_L":"张卓佳,
