In this work, crystal-violet (CV) dye was removed using a chemical carbonization process to create carbonized sargassum algae (CSA), which poses less environmental danger. The produced CSA is examined using a scanning electron microscope and a Fourier-Transform Infrared spectrometer. The following parameters were measured: pH, contact duration, tem...

... electron micrographs (SEM) of carbonized sargassum algae at low and high magnification are shown in Figure 2. When the sargassum algae was treated with nitric acid at high temperatures, it disintegrated dramatically and the surface of the sample began to shrink, possibly due to nitric acid's partial loss of hemicellulose. ...
Context 2
... other words, as the pH of the CSA increases, the surface becomes negatively charged, causing the polarization of the electric double layers to reverse. As a result, as seen in Figure 2, the adsorption percentage of diffuse CV dye decreases (b)(69). The maximum amount of adsorbed at pH 7. ...
