Image Number D112-45 **Caption for November/December 2011 *Agricultural Research* magazine article, "Carefully Unraveling the Intricacies of Biochar."**A column filled with poultry litter-based activated chars is put to the test by chemist Isabel Lima (right) and Bonnie Dillon by letting a solution of copper ion pass through. The solution turns clear as the copper ions are absorbed by the activated chars. **Caption for July 2005 *Agricultural Research* magazine article, "The Ultimate Trash To Treasure: *ARS Research Turns Poultry Waste into Toxin-grabbing Char*."**In a test of carbon’s ability to adsorb metals from water, student technician Bonnie Dillon (left) and chemist Isabel Lima run a copper ion solution (blue liquid) through a column of broiler manure-based carbon. When the copper is removed, the solution becomes clear. Photo by Stephen Ausmus.  640 pixels wide: (d112-45.jpg)   Please visit our Image Gallery
