Use of Almond Tree (Terminialia cattapa) Bark Powder for Adsorption of Methylene Blue, a Basic Dye from Aqueous Solutions
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 4
Abstract
dsorption studies of methylene blue (MB) on Almond tree bark powder (ATBP) were carried out by batch experiments. The parameter studied includes initial dye concentration, adsorbent dose, pH, agitation time, agitation speed, particle size of adsorbent and temperature. The best fitting isotherm models was found to be Langmuir and Freundlich (R2 ≈ 0.99). As the particle size of adsorbent increased from > 120 mesh, 120≤ 85mesh, 85≤ 60 mesh, the monolayer (maximum) adsorption capacities (qm) were found to decreased from 333.333, 200, 166.667 mg/g of ATBP respectively. Lagergren pseudo -second order model best fits the kinetics of adsorption. Intra particle diffusion plot showed boundary layer effect and larger intercepts indicates greater contribution of surface sorption in rate determining step. Adsorption was found to increase on increasing pH, increasing temperature and increasing particle size. Thermodynamic analysis showed that adsorption was favourable, spontaneous, endothermic physical adsorption and increased disorder and randomness at the solid- solution interface of MB with the adsorbents. ATBP was found to have excellent adsorption capacity.
