Study on Adsorption Properties of Lignocellulose/ Organic Montmorillonite Nanocomposites
Lignocellulose/organic montmorillonite (LNC/OMMT) nanocomposites have been prepared by the solution intercalation method from pristine montmorillonite (MMT),using Cetyl three methyl brominated ammonium(CTAB) as the reactive compatibilizer between LNC and MMT .Then the nanocomposites were characterized by Fourier transform infrared(FT-IR),X-ray diffraction(XRD) and Scanning electron microscope(SEM).Diffferent preparation conditions influence of the adsorption property on nanocomposites for Congo Red were studied. The characterization results indicate that LNC molecules have intercalated into the interlayers of OMMT and increased its interlayer distance. The intercalated structure was formed in LNC/OMMT nanocomposits. The adsorption result show that the nanocomposits have higher adsorption capacity with weight ratio of LNC to OMMT 6:1, reaction temperature 50°C, reaction time 6 h, concentration of NaOH 10%.
