Abstract

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.

摘要

青绿石是低成本且容易获得的天然粘土矿物之一。它的特殊特征，包括钾阳离子活性，层状结构和吸收能力，说明了对该矿物的广泛兴趣。就水处理而言，这是特别有希望的。钙铝石的组成取决于形成条件，这导致不同的吸附性能。在这里，我们通过粒度分析，电磁分离，X射线荧光分析，电感耦合等离子体质谱，岩石学，扫描电子显微镜，X射线衍射分析等手段研究了Bakchar矿床独特的绿泥石的吸附参数和物理特性。 ，氮气热脱附法，反相伏安法。最后，我们测试了这种矿物作为吸附剂。所研究的青花瓷精矿具有最佳的比较吸附性能。结果表明，Bakchar矿床的辉绿岩对重金属是一种廉价且前景广阔的吸附剂。
