The invention relates to an absorbent solution, and to a method for implementing said solution, for eliminating acid compounds contained in a gaseous effluent, comprising water and at least one diamine of general formula (I), in which: the radicals R1, R2, R3 are each selected indifferently from a methyl radical and a hydroxyethyl radical, and at least one radical from R1, R2, and R3 is a methyl radical. L'invention concerne une solution absorbante, et un procédé mettant en œuvre cette solution, pour éliminer des composés acides contenus dans un effluent gazeux, comportant de l'eau et au moins une diamine répondant à la formule générale (I), dans laquelle: les radicaux R1, R2, R3 sont chacun choisi indifféremment parmi un radical méthyle et un radical hydroxyéthyle, et au moins un radical parmi R1, R2, et R3 est un radical méthyle.
