Glauconite is one of natural clay minerals that are low-cost and readily available. Its specific characters, including potassium cations activity, layered structure and absorption capacity, explain the comprehensive interest to this mineral. It is especially prospective in regard of water treatment. Glauconite composition depends on the formation conditions, which lead to different sorption properties. Here we studied the sorption parameters and physical characteristic of unique glauconite of the Bakchar deposit by mean of granulometric analysis, electromagnetic separation, X-ray fluorescence analysis, inductively coupled plasma-mass spectroscopy, petrographic studies, scanning electron microscopy, X-ray diffraction analysis, nitrogen thermal desorption method, inversion voltammetry. Finally, we tested this mineral as a sorbent. The studied glauconitic concentrate has the best comparative sorption properties. Results show that glauconite of the Bakchar deposit is a cheap and prospective sorbent for heavy metals.
海绿石是一种天然黏土矿物,具有成本低、来源广泛的特点。其特有的钾离子活度、层状结构和吸附能力使其成为研究热点,在水处理方面具有广阔的应用前景。海绿石的组成取决于其形成条件,这导致了不同的吸附性能。本研究通过粒度分析、电磁分离、X 射线荧光分析、电感耦合等离子体质谱、岩相学研究、扫描电子显微镜、X 射线衍射分析、氮热脱附法和反扫伏安法,对巴克恰尔矿床特有的海绿石的吸附参数和物理特性进行了研究。最后,我们测试了这种矿物作为吸附剂的性能。研究结果表明,巴克恰尔矿床的海绿石浓缩物具有较好的重金属吸附性能,是一种廉价且有前景的重金属吸附剂。
