Nanoporous Copper Doped Aluminium Pillared Montmorillonite for Dye‐containing Wastewater Treatment
Copper doped aluminium pillared montmorillonite (Cu‐Alpill‐MMT) was prepared by adding Cu2+ into the suspension of aluminium pillared montmorillonite (Alpill‐MMT) using high power ultrasonic treatment and calcining to CuO at 500 °C. The XRD and XRF data revealed that the doped CuO partially occupied both internal and external surfaces of the Alpill‐MMT. The N2 adsorption/desorption analysis showed that the Cu‐Alpill‐MMT consisted of slit‐like mesopores with two ranges of pore diameter, i.e. ~3.8 nm and ~6‐30 nm. The Cu‐Alpill‐MMT exhibited the superior adsorption capacity for Basic Yellow 1 (BY1), however, it hardly adsorbed Reactive Orange 16 (RO16). The decolorization of RO16 was achieved when the H2O2 or H2O2/UV was introduced into the treatment system together with the Cu‐Alpill‐MMT, acting as heterogeneous catalyst for Fenton or photo‐Fenton oxidation processes, respectively. The Cu‐Alpill‐MMT could exhibit the antibacterial activity after intimate contact with Escherichia coli ATCC®25922 under JIS L 1902: 1998 (Qualitative) test method.
