제목 Adsorption of synthetic dyes using MRA (Mongolian anthracite)-based activated carbons
초록 Synthetic dyes are very useful chemicals in our life but they are harmful to ecosystem and human beings because of toxic, carcinogenic, and mutagenic properties. Therefore, synthetic dyes must be removed from water streams. Many technical methods have been suggested till now to remove synthetic dyes from water bodies. Among them, the physical method based on adsorption would be plausible since adsorption has several advantages such as high efficiency and low operational cost.
In this work, Mongolian anthracite was activated with KOH as an active agent after physically mixing of precursor and agent. During activation, several variables such as temperature, the ratio of agent/precursor and the flow rate of nitrogen. The prepared activated carbons were characterized by XRD, BET and TEM. In addition, the adsorption of synthetic dyes, Reactive Red 120 and Rhodamine-B, were carried out using activated carbons prepared above in a batch reactor. The concentrations of two dyes before and after adsorption experiments were analyzed using UV spectrometer. All equilibrium data were fitted with Langmuir and Freundlich isotherm equations.
