Study on the Leaching Performance of Chrome in Waste Leather Products

Abstract:

The leaching experiments of finished pigskin, finished cowhide and finished sheepskin are conducted in this essay with liquor of different pH to research the leaching performance of chrome. After continuous leaching of 120 hours, it turns out that chrome is leached out most under the effect of the liquor whose pH is 2, and it is intermittent. Comparing the content of extracted chrome, it turns out those samples, treated with liquor whose pH is 2, has increased values, which proves that the stability of chrome in leather declines.
