<p>A method for water purification which comprises bringing a scavenger containing both a compound represented by general formula (I) and metal ions capable of square planar coordination or octahedral coordination into contact with water containing molecules to be scavenged and bringing a porous solid into contact with water containing molecules to be scavenged. In general formula (I), one of R2, R3 and R4 is Ry present at a position meta or para to Rx; Rx and Ry are each independently a heterocyclic substituent described below; R1, R2, R3, R4 and R5 except Ry are each independently hydrogen, a substituted or unsubstituted hydrocarbon group having 1 to 30 carbon atoms, or a sulfonic acid group, with the proviso that they are not simultaneously hydrogen; and in the heterocyclic substituent, R6 and R7 are each independently hydrogen or methyl and A is a 5- or 6-membered heterocyclic group containing at least one nitrogen atom.</p> |
