A separation arrangement isolates chlorine, sodium and possibly other ions from water. The ion-laden water is applied to at least one graphene sheet perforated with apertures dimensioned to pass water molecules and to not pass the smallest relevant ion. The deionized water flowing through the perforated graphene sheet is collected. The ions which are not passed can be purged. In another embodiment, the ion-laden water is applied to a first graphene sheet perforated with apertures dimensioned to block chlorine ions and through a second graphene sheet perforated with apertures dimensioned to block sodium ions. The concentrated chlorine and sodium ions accumulating at the first and second perforated graphene sheets can be separately harvested. |
