Monodisperse polymer microcapsules were prepared using a microfluidic approach via Schiff base reaction between Fe aminoclay and glutaraldehyde. The amine groups of Fe aminoclay encapsulated in microcapsules and the surface morphology of microcapsules were demonstrated by scanning electron microscopy, Fourier transform infrared spectroscopy and optical microscopy. It acts as an effective adsorbent for anionic dyes due to the presence of many cationically charged amine groups on the surface of the capsule. The prepared microcapsules were evaluated as adsorbents for the removal of MO, CR, MB dyes from aqueous solutions at various process parameters such as dye concentration, contact time and pH. The adsorption capacity of microcapsules on anionic dyes was measured and mounted using the Sips isotherm model. After the adsorption of the anionic dye was complete, the cyclic adsorption/desorption efficiency of microcapsules was maintained close to 5 times. |
