PROBLEM TO BE SOLVED: To provide a dialysate solution regeneration method, a dialysate solution regeneration device, and a preliminarily adjusted cation exchange resin that, on the assumption that a used dialysate solution is caused to come into contact with a cation exchange resin to cause urea contained in the used dialysate solution to adhere to the cation exchange resin, can adjust pH of the dialysate solution from which urea is removed to an appropriate range.SOLUTION: A dialysate solution regeneration method includes a urea removal process in which a used dialysate solution 22 used for artificial dialysis is caused to come into contact with a cation exchange resin 80 so as to cause urea contained in the used dialysate solution 22 to adhere to the cation exchange resin 80, and a pH adjusting process in which the used dialysate solution 22 is caused to come into contact with an anion exchange resin 90 to adjust pH of the used dialysate solution 22. A dialysate solution regeneration device 100 includes a urea removal tank 130 in which the used dialysate solution 22 is caused to come into contact with the cation exchange resin 80, and a pH adjusting tank 140 in which the used dialysate solution 22 is caused to come into contact with the anion exchange resin 90.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】使用済透析液を、陽イオン交換樹脂に接触させて当該陽イオン交換樹脂に使用済透析液に含まれる尿素を付着させることを前提とし、かつ、尿素が除去された透析液のpHを、適度な範囲に調整可能な透析液再生方法、透析液再生装置、および予備調整陽イオン交換樹脂を提供する。【解決手段】透析液再生方法は、人工透析に使用された使用済透析液22を陽イオン交換樹脂80に接触させ、使用済透析液22に含まれる尿素を陽イオン交換樹脂80に付着させる尿素除去工程と、使用済透析液22を陰イオン交換樹脂90に接触させて使用済透析液22のpHを調整するpH調整工程と、を有し、透析液再生装置100は、使用済透析液22を、陽イオン交換樹脂80に接触させる尿素除去槽130と、使用済透析液22を、陰イオン交換樹脂90に接触させるpH調整槽140と、を有する。【選択図】図1
