AboutDavid L. Russell, PE Expertise I`m a Chemical,Civil and Environmental Engineer and have a number of projects in all phases of the environment.
I have worked in the chemical industry and am active in professional societies, and am currently on an industrial wastes committee for the Water Environment Federation, and have taught courses in remediation in the US and abroad.
I have written one book on Remediation of petroleum Contaminated Sites, and have a second book on PRACTICAL WASTEWATER TREATMENT to be published by John Wiley in September, 2006. I've also written over 30 articles on various elements of environmental problems and cleanup. Most Recently, I have addressed a NATO Scientific and Techical Conference on Ecoterrorism, and have worked with the same group on remediation of sites contaminated with Chemical Warfare Agent materials and othe materials as well. . I can answer q`s about Chemical and Environmental Engineering, land development, air pollution, water pollution, soil and water cleanup, combustion, international environmental problems, industrial processes chemical processes. Civil and Environmental and Chemical Engineering. Overall, I have over 35 years of experience in this area. Note: I do not answer homework questions
Experience I love work in the third world and developing areas
because it is challenging and one can get a sense of accomplishment.
Question Our problem is about dissolving nitrobenzene in water and measure as COD. Can we prepare a nitrobenzene solution? I mean that how can we dissolve nitrobenzene to prepare a stock solution. Is it possible? If we prepare nitrobenzene Can we measure nitrobenzene as COD (chemical oxygene demand)?
Answer Interesting Question. The solubility of nitrobenzene is about 0.19 gm/L. The best way to calculate the COD is to oxidize everything to CO2, water, and NO3? (I'm not sure about the NO3 and it might affect your results). Then get out your copy of Standard Methods and run the test. My best guess is that you can prepare a standard solution given the approximate values I obtained from Wikipedia. You can check with a manufacturer of Nitrobenzene for precise data or take the raw material you have and check the MSDS which came with it.
