Lead electrocapture on hydroxyapatite coated electrodes.
Hydroxyapatite coated electrodes were made by a hydrolysis reaction involving silanes and hydroxyapatite particles on stainless steel. Aqueous lead ions were captured on the coatings with or without electromigration. Results depend on coating thickness, supporting electrolyte and the presence of the electric field. It was found that this new electrocapture method can remove lead from solutions down to ppb levels.
