以钠基膨润土为原料,将易燃性煤和淀粉按一定比例混入其中,挤压造粒,高温灼烧,再进行有机物覆盖,得多孔有机膨润土。再用十二烷基磺酸钠(SDS)改性钠基膨润土,所获得多孔有机膨润土经X光衍射(XRD)、红外光谱(FT-IR),热失重分析(TGA)表明,SDS已有效进入膨润土层间,其层间距由0.9645nm扩大至3.1490nm。研究了多孔颗粒有机膨润土对印染水溶液的脱色效果。
Taking sodium bentonite as raw material, the flammable coal and starch are mixed into the mixture according to a certain proportion, extruded and granulated, burned at high temperature, and then covered with organics to obtain porous organic bentonite. Sodium dodecyl sulfate (SDS) was used to modify sodium bentonite. The obtained porous organic bentonite was characterized by X-ray diffraction (XRD), infrared spectrum (FT-IR) and thermogravimetric analysis (TGA) Into the bentonite layer, the interlayer spacing expanded from 0.9645nm to 3.1490nm. The effect of porous organic bentonite on the dyeing and printing aqueous solution was studied.
