Kinetic Modeling Characterization of Cellulose Modified Surface for Methylene Blue Removal from Aqueous Media

In this work, commercial cellulose is modified with allylthiourea (Cel‐AT) to remove methylene blue (MB) from aqueous solution. Characterization study includes FTIR analysis along with UV spectrophotometer. A variety of physico‐chemical properties such as kinetic, total sorption capacity loaded and pH effect by using Cel‐AT sorbent is carried out. The main finding is the adsorption total capacity of Cel‐AT for MB is three times more than commercial cellulose (Cel) when the concentration of MB increases in batch mode. In kinetic study, the MB removal efficiency is at 90% after 5 min of removal using Cel‐AT as a sorbent and Cel‐AT fulfil pseudo second order of reaction. The optimum MB removal is at pH 11 with 95% of removal. There is spectral peak which is observed in the spectrum of FTIR and it is addressed accordingly. As a conclusion, the suggested method improves the quality of MB sorption onto the Cel‐AT in terms of contact time and less laborious.
