Eucalyptus lenceota Based Activated Carbon

100 страниц. 2015 год.
LAP Lambert Academic Publishing
The eucalyptus lenceolata wood was collected and converted into carbon. The carbon was then characterized by BET surface area, scanning electron microscopy (SEM), FTIR and energy dispersive spectroscopy (EDS) techniques. Adsorption of some dyes (basic green 5 and Methylen blue) were studied on the treated and raw sample of carbon powder by kinetics adsorption at different adsorption temperatures. Linear models were used for analysis adsorption kinetics studies. From adsorption kinetic data the thermodynamic parameters were calculated for finding the adsorption mechanism. The results show that the adsorption process is spontaneous process. The negative value of entropy shows that the molecules on the surface of adsorbent take an oriented position on the adsorbent surface. All models were found best fit for the adsorption data.
