Gelatin reacted with Copper (II) ion in dilute aqueous solution to form water-soluble and foamy complex. The good effect of copper removal by gelatin was observed by the foam treatment of this solution. And also lead was effectively removed by the same treatment. The effect was further raised by the adsorption treatment using gelatin powder before the foam treatment. About 99 % of copper in the pH range from 6.5 to 7.3 and nearly 100% of lead about pH 7.0 was removed respectively.
