Abstract

Iron (III) diethyldithiocarbamate complex (Fe(DTC)) of the general formula [Fe(S2CN(Et)2)3] was synthesized and characterized using chemical, thermogravimetric (TGA/DTG), and (FT-IR) analysis. The vapor adsorption tests verified that the Fe(DTC) was mesoporous and that the pore surface area was 16.73 m2/g, according to the N2 adsorption-desorption isotherm. The main aim of this study is to eliminate methyl green (MG) from water via Fe(DTC) adsorption. The adsorption experiments, that investigated the influence of pH and mass, demonstrated that both of these factors have an impact on adsorption. The optimal conditions for MG adsorption onto the Fe(DTC) metal complex were 0.05 g for a Fe(DTC) mass and a pH value of 7 ± 0.2. At 333 K, the maximum capacity for the Fe(DTC) metal complex adsorbent was 26 mg/g for MG. At 180 min, the elimination efficiency for MG dye was approximately 87%. Based on the kinetic experiments, the pseudo-second-order model was determined to be the most appropriate for assessing the adsorption process. The mechanism of adsorption was studied by appropriating the adsorption data to the Temkin, Freundlich, Langmuir, Temkin, and Radushkevich models. The results can be adequately described by the Langmuir model.
