Simultaneous Adsorption of Methyl Orange and Heavy Metals from Solution Using Fly Ash
In a wastewater resulted from the dyes finishing industry there are amounts of dyes (very common Methyl Orange) and heavy metals resulted mainly from the organo-metallic dyes. Heavy metals (Cd2+ and Cu2+) advanced removal is usually proposed via adsorption and the use of modified fly ash as adsorbent represents a sustainable solution. The paper presents the results obtained in investigating the effect of methyl orange adsorbed onto the fly ash with modified surface, on the removal efficiency of cadmium and copper ionic species, considering the final application: a single step treatment process applied for wastewaters containing both heavy metals and dyes. The adsorption mechanisms are discussed based on the kinetic results and on the Langmuir model.
