The present invention relates to an acid concentrate dialysis composition an acid concentrate dialysis composition comprising a mixture of citric acid and citrate, having pH of less than 3.0, wherein the total concentration of citrate is between 35 mM and 450 mM, and wherein the amount of citric acid is more than 50 % of the total concentration of citrate. The acid concentrate dialysis composition is to be combined to form a dialysis solution having a total concentration of citrate of between 1 and 6 mM.La présente invention concerne une composition de dialyse de concentré acide comprenant un mélange d'acide citrique et de citrate, ayant un pH inférieur à 3,0, la concentration totale de citrate étant comprise entre 35 mM et 450 mM, et la quantité d'acide citrique constituant plus de 50 % de la concentration totale de citrate. La composition de dialyse de concentré acide doit être combinée pour former une solution de dialyse ayant une concentration totale de citrate comprise entre 1 et 6 mM.
