| Abstract | ||
| Organic matters (OM) present in phosphoric acid such as humic acid are chemically reactive and have a wide range of functionalities that vary according to the origin of the minerals. A study was conducted to determine the effectiveness of modified active carbon species in sorbing organic matter from commercial phosphoric acid. Various factors such as shaking time, adsorbent dose (g/ml), temperature, mechanical stirring speed, and phosphoric acid concentration were examined to determine their effect on the adsorption process of raw carbon (R-C) and activated carbon (A-C). The results showed that the sorption process was effective for both high-strength and diluted phosphoric acid, but it was more preferable in the case of the latter. The adsorption capacity was found to be 22 and 28 mg/g for R-C and A-C, respectively. The equilibrium adsorption data were analyzed using the Langmuir and Freundlich isotherms. The results showed that the adsorbents followed the Langmuir model. | ||
