The Preparation and Characterization of Phosphoric Acid modified Ferula Communis Biomass and its Application in the Removal of BR-9 Dye

In this study, the potential of Ferula Communis biomass (FC) was evaluated for removal of cationic dye from aqueous solution. Phosphoric acid modified FC was utilized to remove basic red 9 (BR-9) under varying adsorption parameters such as pH, temperature, contact time, adsorbent dosage, and ionic strength. The adsorption process using modified FC (PFC) was evaluated under isothermal conditions and Langmuir model showed monolayer adsorption of 354.89mg/g with high R2 value of 0.9997 compared to Freundlich model. The adsorption process was evaluated under various kinetic models. The experimental results indicated that BR-9 removal fit well with pseudo-second order kinetic and the treatment process is exothermic and spontaneous in nature. The obtained results showed that PFC can be used as an alternative adsorbent for the treatment of dye-containing wastewaters.
