Optimization of crystal violet adsorption on common lilac tree leaf powder as natural adsorbent material

<p>In this study the efficiency of crystal violet dye removal from aqueous solutions using lilac tree leaf powder as adsorbent material was tested. After surface analysis by SEM and FTIR technics, influence six controllable factor on adsorption process assesses a L27 Taguchi experimental design. The optimum conditions factors significance were established evaluation signal-to-noise ratio (S/N). ANOVA revealed percentage contribution each in removal. Langmuir isotherm pseudo-second order kinetic model characterized maximum capacity higher than other similar adsorbents previously used literature. thermodynamic parameters reveal favorable, spontaneous endothermic based physisorption mechanism.</p>
