Abstract:
A surfactant factionalized m a g n e t i c mesopores titanium with layered double hydroxide(Fe3O4@MCM@TiO2@LDH) was synthesized for the removal of cationic dye, methyleneblue from waste w a t e r samples. This adsorbent prepared with a Tio2 loaded onmesopore (MCM-41) was coated with Fe3O4 as the main core and encapsulated in Cu-Fe-layered double hydroxide (Cu-Fe-LDH) as nano platelet shell. An anionicsurfactant, sodium dodecyl sulfate (SDS) was used to modify the positive adsorbentby through hemimicelles/admicelles process. T h e surface chemical characteristics ofthe prepared Fe3O4@MCM@TiO2@LDH were studied by the IR, XRD, and EDXanalytical techniques. Also, the surface morphology of adsorbent, the BET specific surface areaand BJH pore sizes were obtained. The effect of effective parameters for the removal the dyewas also studied. The adsorption data fitted with the Langmuir model showed shortequilibrium time with the maximum capacity uptake of 217.39 mg g-1. Regenerationof the adsorbent was performed with methanol.
