Description
Summary:Formaldehyde (HCHO) is the most common aldehyde in the environment. It is widely present in aquatic and air environment as one of environmental pollutants. It is commonly used for manufacturing building materials and various household products. Now, it has become a matter of concern because it is mutant and carcinogenic, and an irritant to eyes and skin, therefore its removal from water is very important. Adsorption has an edge over the other techniques due to its simplicity, cost effectiveness, less time consuming and environmental friendly behavior. In present study, adsorption efficiency of Amberlite IRA-910 has been examined. Relevant parameters such as pH, adsorbent dose, adsorbate concentration, shaking speed, volume and shaking time have been studied thoroughly. Ultraviolet-visible spectroscopy was used to determine the formaldehyde content in the water. The isothermal study was carried out using the Langmuir, Freundlich and D-R isotherm. Results showed that Amberlite IRA-910 has better adsorption efficiency for the removal of formaldehyde at lower as well as higher concentrations. The thermodynamic and kinetic parameters have also been calculated.
