Biological Reduction of Perchlorate from Spent Modified Reed Mediated by an Enriched Microbial Culture

Figure 5

Perchlorate recovery values obtained showing dependence on the volume of nitric acid added. The total volume added was constant at 3.0 mL. For example, if 0.2 mL of concentrated nitric acid (∼15.9 )M was added, 2.8 mL of water was also added.
