  摘要：

  研究了使用经离子液体（IL）改性的蒙脱石去除a菜染料的方法。合成了一种离子液体（1-甲基，3-癸基咪唑鎓），并通过核磁共振（1 H和13 C NMR），傅里叶变换红外（FT-IR）光谱，高分辨率质谱（HR-MS）进行了表征以及热重量分析和差热（TGA / DCS）分析。此后，通过添加超过Na + -Mt阳离子交换容量（CEC）的IL，使用离子液体对钠蒙脱石（Na + -Mt）进行改性，以形成疏水性蒙脱土，该表面具有带正电的表面。使用能量色散X射线分析仪（EDX）测定Na的化学成分+-山 使用FT-IR，扫描电子显微镜（SEM），X射线衍射（XRD）和Brunauer-Emmett-Teller（BET）方法对改性蒙脱土（Mt-IL）和Na + -Mt进行表征，并用于吸附研究阴离子a菜染料。观察到Mt-IL的CEC（每100克112毫克当量）比Na + -Mt（每100克89毫克当量）更高。
