| Abstract |
The objective of the project was to evaluate control measurements available for parameters to serve as indicators of biodegradation for a land treatment facility. An earlier paper reported results of comparative studies between wax impregnated graphite electrodes (WIGE) and platinum wire electrodes (PWE) to determine ODR and redox potential (Eh). The study indicated that WIGEs are less susceptible to oxide poisoning, easily fabricated, relatively inexpensive, and more stable in soil than PWEs. A second paper reported the use of WIGEs and PWEs to measure Eh and ODR during biodegradation of glucose and phenol in a soil environment as compared to determining actual biodegradation of those compounds by analytical procedures. The results indicated that Eh and ODR can be suitable parameters for indication of biodegradation of organics by land treatment processes. |
