Determination Of The Wavelength Dependence On The Metal Catalyzed Degradation Of The Herbicide Atrazine, Timothy Bertram
Determination Of The Wavelength Dependence On The Metal Catalyzed Degradation Of The Herbicide Atrazine, Timothy Bertram
Honors Theses
Since the advent of modern herbicide use in the early twentieth century, researchers have been plagued with the obvious problem of herbicide disposal. Most herbicides are specifically designed to resist natural degradation processes so that they can remain effective in the field for a substantial amount of time. In addition, they are also made water soluble so that they can be easily applied to crops. Finally, they are specifically produced to kill undesirable plant species in the quickest and often crudest fashions. Due to these specific properties herbicides pose a general threat to other organisms living in the same geographic …
Biodegradation Of Diflufenican Using Anaerobic Microbial Consortia, Velukumar T. Nanjagowder
Biodegradation Of Diflufenican Using Anaerobic Microbial Consortia, Velukumar T. Nanjagowder
Theses
In this thesis I examine the feasibility of using anaerobic microbial consortia from digested anaerobic sludge to degrade Diflufenican, a fluorinated herbicide released into the environment as a result of agricultural usage. The compound is manufactured by Rhone Poulenc and it is an active ingredient of agricultural herbicides. The anaerobic digested sludge served both as a source of microorganisms and as a growth medium. Initial studies were conducted by making a stock solution of 1 ppm concentration of Diflufenican in acetone, the optimal solubility of the compound as suggested in the material safety data sheet is 0.05 ppm in water. …
