Improved removal of dyes by [sodium alginate/4-methyl-2-(naphthalen-2-yl)-N-propylpentanamide-functionalized ethoxy-silica] composite gel beads
In this paper, the synthesis of [sodium alginate/4-methyl-2-(naphthalen-2-yl)-N-propylpentanamide-functionalized ethoxy-silica] composite gel beads is described. The characterizations were carried out using Fourier Transform InfraRed, Scanning Electron Microscopy, point zero charge and water content...

The characterizations were carried out using Fourier Transform InfraRed, Scanning Electron Microscopy, point zero charge and water content. The morphology of the alginate gel beads are changed after functionalization and are characterized by aggregates of different sizes and irregular shapes.
