Description 162-167
Sonochemical adsorption of basic methylene blue dye (CI 52015) into organophilic bentonite (nanoclay) is explored.
Tetrabutyl ammonium chloride (TBAC) modified nanoclay has showed amorphous exfoliated nature, while N-cetyl-N,N,N
trimethyl ammonium bromide (CTAB) modified nanoclay has revealed intercalating crystalline nature, as supported by X-ray
analysis. Presence of NH₂, CH₂ groups onto nanoclay platelet is confirmed from FTIR spectrum analysis. In presence of
ultrasound, due to decrease in diffusion resistance, both modified nanoclays exhibit higher adsorption due to an easy insertion
of dye into clay platelets. Calculated Langmuir adsorption isotherm, Q₀ and Langmuir constant ‘b’ for TBAC modified nanoclay,
respectively were 0.34 mg/mg 0.246. Intercalating agent has a significant contribution during overall process.
