HYSTERETIC RETENTION OF Pb(II) IN KAOLIN COLUMN
The leaching behavior of metals in soil is key to in-depth understanding of the remediation target and relevant measures for polluted soil. This paper investigated the leaching of Pb(II) from Kaolin column. Solution pH, Pb(II) concentration were recorded and analyzed with a decaying transport theory, separately. The obtained model constants were discussed with emphasis on the hysteretic retention of metal in soil column. The tailing effect of Pb(II) release from polluted soil seems critical to the longterm pollution and requires careful treatment in engineering practices.
