| description | A method of preparing a semi-permeable membrane 79 suitable for reverse osmosis includes contacting a porous artifact 78 with an hydrated metal oxide, to form an hydrated metal oxide coated artifact. Thereafter the hydrated metal oxide coated artifact is contacted with at least one polyelectrolyte selected from the group listed in Claim 1, thereby to form a polyelectrolyte layer in or on the hydrated metal oxide layer. |
