1. Introduction
Palygorskite (PAL) is a sort of natural nano-scale layer-ribbon hydrated magnesium aluminum silicate mineral. PAL exhibits particular
rod-like crystal microstructure with the length of 1–5 μm and diameter of 20–100 nm. The special rod-like geometry generates
numerous nanopores parallel to the crystal rods, which endows PAL with moderate cation exchange capacity, pore structure, large specific
surface area and adsorption properties. Thus, PAL has been widely used in various fields including heavy metal ions and dyes adsorbent,
catalyst support, drug carrier, inorganic crosslinker as well as reinforcement filler of polymer materials [1–8].
PAL是一种层带状的天然纳米水合硅酸镁铝矿物质。它具有特殊的棒状结晶微结构,长1–5 μm,直径 20–100 nm。棒状几何结构能够产生大量平行于晶体棒的纳米孔,这使得PAL具有适中的阳离子交换容量、孔结构、较大的比表面积、吸附性能。因此,PAL和聚合物增强型填料一样,被广泛用于重金属离子吸附剂、染料吸附剂、催化剂载体、药物载体、无机交联剂。 [1–8]. |
