This study mathematically models the solubility of hydrogen sulfide in ten ionic liquids including 1-(2-hydroxyethyl)-3-imidazolium [Hoemim](+) with three different anions, 1-ethyl-3-methylimidazolium [emim](+) with two different anions, 1-hexyl-3-methylimidazolium [hmim](+) with two different anions, and 1-butyl-3-methylimidazolium [bmim](+) with three different anions. The modeling was performed by van der Waals (vdW) equation of state as a phi-phi approach in which the modified van der Waals-Berthelot mixing rule is used. The critical properties of ionic liquids have been estimated by a group of supplementary methods suggested by Valderrama and Robles, known as the modified Lyderson-Joback-Reid method. It is concluded that since the absolute average relative deviation is less than 1%, the developed model has a high accuracy.
