Abstract:
1. A method for preparing a peritoneal dialysate having a reduced carbonyl compound content, the method comprising: (a) contacting the peritoneal dialysate with a surface having immobilized thereon a carbonyl compound-trapping agent; and (b) separating the peritoneal dialysate from the surface having the carbonyl compound-trapping agent immobilized thereon; wherein said carbonyl compound-trapping agent is selected from the group consisting of guanidine derivatives, hydrazine derivatives, 5-membered heterocyclic compounds having 2 nitrogen atoms, 5-membered heterocyclic compounds having 3 nitrogen atoms, 5-membered heterocyclic compounds having a nitrogen atom and a sulfur atom, 5-membered heterocyclic compounds having a nitrogen atom and an oxygen atom, nitrogen-containing 6-membered heterocyclic compounds, nitrogen-containing condensed heterocyclic compounds, sulfur and nitrogen-containing condensed heterocyclic compounds, sulfur-containing condensed heterocyclic compounds, oxygen-containing condensed heterocyclic compounds, nitrogenous compounds, quinones, aliphatic dicarboxylic acids, silicides, organogermanes, alkylamines, aromatic compounds, polypeptides, vitamins, SH group-containing compounds, SH group-containing proteins, biguanide agents, ion exchange resins, and inorganic compounds.
