摘要：

Various treatments of a lead-containing gel to reduce the migration of lead during drying were examined as a basic study for the preparation of gradient-index glass rods. The migration of lead ions, which had been introduced in the form of aqueous lead acetate solution, could be reduced by the extraction of water with isopropanol and acetone in advance of drying of a gel at ambient atmosphere. © 1990.
