 en Removal of malachite green from water by Firmiana simplex check for this species in other resources wood fiber
Pan, X. & Zhang, D.

Abstract

This study shows that wood fiber of Phoenix tree ( Firmiana simplex check for this species in other resources ) is an effective adsorbent for malachite green (MG). MG sorption behavior onto the wood adsorbent was investigated in this study. Basic condition was favorable for MG adsorption to the adsorbent. The pseudo second order equation well described MG adsorption onto the wood adsorbent. The Freundlich Isotherm could describe the sorption data. The positive value of ΔH0 showed that adsorption of malachite green onto the wood adsorbent was endothermic. The negative values of ΔG at various temperatures indicate the spontaneous nature of the adsorption process.
