Exploring a Green Bio-Nanocomposite for the Removal of Crystal Violet Dye


Exploring a Green Bio-Nanocomposite for the Removal of Crystal Violet Dye

Anam Mirza, Rais Ahmad

In the present chapter alginate/activated carbon bio-nanocomposite was evaluated for the removal of crystal violet dye from aqueous solution. The bio-nanocomposite was characterized by SEM, EDX and TEM analysis. In batch adsorption experiments effects of various parameters such as pH, contact time, concentration and temperature were performed in order to evaluate the adsorption process. The adsorption was best described at pH 7.2, contact time 300 min and temperature 293 K. The experimental data were evaluated for isotherm and kinetic studies. Langmuir and Pseudo-second order models were found to be the best-fitted model. Therefore, the present bio-nanocomposite was found to be an excellent adsorbent for the removal of toxic dye from wastewater.
