The ash was used as biosorbent without any physical or chemical treatment. The biosorbent was characterized by using various techniques such as Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The particle size and surface area were measured using particle size analyzer and Brunauer-Emmett-Teller equation (BET), respectively. The SEM and BET results expressed that the adsorbent has porous nature. Effects of various conditions such as initial concentration of methylene blue (MB), initial pH, contact time, dosage of biosorbent, and stirring rate were also investigated for the adsorption process. The rate of the adsorption of MB on biomass sample was fast, and equilibrium has been achieved within 1 hour. The kinetics of MB adsorption on biosorbent was studied by pseudo-first- and pseudo-second-order kinetic models and the pseudo-second-order has better mathematical fit with correlation coefficient value (R 2) of 0.999. The study revealed that C. polygonoides ash proved to be an effective, alternative, inexpensive, and environmentally benign biosorbent for MB removal from aqueous solution. © 2015 Asma Nasrullah et al. date: 2015 publisher: Hindawi Publishing Corporation official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84947648703&doi=10.1155%2f2015%2f562693&partnerID=40&md5=412be1be065d434e2d20ed307231522a id_number: 10.1155/2015/562693 full_text_status: none publication: Scientific World Journal volume: 2015 refereed: TRUE issn: 23566140 citation: Nasrullah, A. and Khan, H. and Khan, A.S. and Man, Z. and Muhammad, N. and Khan, M.I. and Abd El-Salam, N.M.
