Abstract

The new polymer–mineral composite materials have been obtained by in situ immobilization of poly-[5-(p-nitrophenylazo)-8-methacryloxyquinoline] on the saponite of Tashkivsky deposit (Sap-AzoQN) and clinoptilolite of the Tushinsky deposit (Clin-AzoQN) surface. The fact of polymer immobilization on the surface of minerals by the selected method was confirmed by thermogravimetric analysis combined with mass spectrometry and IR spectroscopy. Scanning electron microscopy showed that the immobilized polymer is located on the surface of both minerals in the form of needles, located in different directions to the surface, and acicular formations. The properties of the composite materials have been determined by means of a sorption test when removing ions Pb²⁺, Fe³⁺, and Cu²⁺ from the model solutions in static conditions. A twofold increase in the sorption capacity of the Sap-AzoQN composite for Cu(II) and Pb(II) ions and a 5.6-fold increase in the Clin-AzoQN composite for Fe(III) ions were recorded compared to the original minerals. As a result, composite materials revealed high-efficiency sorption of heavy metals.

用聚[5-(对硝基苯偶氮)-8-甲基丙烯酰氧基喹啉]原位改性的乌克兰多孔铝硅酸盐矿物对有毒金属离子的吸附特性

通过将聚-[5-（对硝基苯偶氮）-8-甲基丙烯酰氧基喹啉]原位固定在塔什干夫斯基矿床的皂石（Sap-AzoQN）和图辛斯基矿床的clinoptilolite（Clin-AzoQN）表面，获得了新型聚合物矿物复合材料。热重分析结合质谱法和红外光谱法证实了所选方法在矿物表面固定聚合物的事实。扫描电子显微镜显示，被固定的聚合物以针状和针状的形式分布在两种矿物的表面，针状和针状的分布方向不同。在静态条件下，通过吸附试验从模型溶液中去除离子 Pb2+、Fe3+ 和 Cu2+，确定了复合材料的特性。与原始矿物相比，Sap-AzoQN 复合材料对 Cu(II) 和 Pb(II) 离子的吸附能力提高了两倍，Clin-AzoQN 复合材料对 Fe(III) 离子的吸附能力提高了 5.6 倍。因此，复合材料显示出对重金属的高效吸附。
