Abstract
- This paper discusses the use of calcium carbide residue to absorb iron (II) ions in acidic water. In this research, the acidic water was made synthetically using FeSO4. 7H2O and processed by batch adsorption methodusing calcium carbide residue as an adsorbent. This study aims to determine the characteristics of adsorbent, absorption capacity and removal efficiency. The concentrations of Iron (II) ions was varied between 40 and 100 mg/L, at the pH of solution of 2.5, adsorbent mass of 5 g, and stirring speed of 200 RPM. Contact time was ranged from 5 to 60 min. The experimental results show that at the 60 min contact time, calcium carbide residue was able to increase the pH from 2.5 to 12.8 and decreased the iron concentration by 99.73%. The process of adsorption of iron (II) metal ions with calcium carbide residue was fitted well with Langmuir’s isotherms adsorption model. [ABSTRACT FROM AUTHOR]
