いる。2. Description of the Related Art A generally used peracetic acid composition contains a large amount of metals such as Pb, Cr and Ca. As is well known, heavy metals such as Pb and Cr have an adverse effect on the human body, and there is a concern that the use of the peracetic acid composition as a disinfectant may affect the human body. Further, it is known that light metals such as Ca accumulate as Ca salts inside the dialysis membrane, thereby deteriorating the permeability of the membrane and shortening the membrane life. Therefore, there is a need for a peracetic acid composition from which these metals have been removed.
