The synthesis of novel material, tin(IV) chelate com-pound, was carried out using simple and inexpensive Schiff base ligands. This novel material was used for the first time as an adsorbent to remove murexide dye from a model aqueous solution. 1 H-NMR,13 C-NMR, Fourier-transform infrared spectroscopy, MS, and elemental analysis techniques were performed for the characterization of the new tin-based adsorbent and the open structure of the compound was proposed. Murexide dye removal from a model aqueous solution was performed by examining five important factors of adsorption. Batch adsorption is the easiest way to remove dyes at a low cost. The optimum parameter values to maximize the adsorption efficiency were obtained at pH 3, 100 mg/L dye concentration, 20 min of contact time, 40 mg adsorbent dose, and 25°C. The highest adsorption recovery value and the adsorption capacity found at optimum parameters were 99.00%, and 248.8 mg/g, respectively. Three adsorption isotherms were calculated at 25°C. The highest R2 value was found at 0.99 for the Langmuir isotherm model, the adsorp-tion kinetic obeyed the pseudo-second-order kinetics, and the thermodynamic data suggested a spontaneous and exothermic process.
