Total organic carbon/total nitrogen analyzer
FY 2007-08
Summary
Funds are requested to purchase a "total organic carbon/total nitrogen (TOC/TN) analyzer". The requested instrument is combustion based total organic/inorganic carbon as well as total nitrogen analyzer which is equipped with an auto-sampler. The requested TOC/TN analyzer is to support the development of disappearance and kinetic rate models, monitoring degradation of parent pollutants and their intermediates in wastewater, and the optimization of combined photochemical and biological processes for industrial and municipal wastewater treatment. The primary use of the TOC/TN analyzer is to determine the photochemical and biological degradation rates by determining the reliable data for total organic carbon and total nitrogen utilized during the course of both photochemical and biological reactions. Parent compounds in industrial wastewater treated by advanced oxidation technologies and biological processes may disappear while there are still many other organic and inorganic compounds present in the system. This is due to the fact that intermediates are generated as a result of these reactions. The kinetic modeling of multicomponent systems is not only complicated but also it may not be accurate if all intermediates during the course of reactions are not taken into account. Due to the limitations and drawbacks of biological oxygen demand (BOD), chemical oxidation demand (COD), and other specific compound disappearance, it is generally difficult to generate enough reliable data points per sample for good kinetic parameter estimation. Therefore, the total organic/inorganic carbon and nitrogen balances are necessary in developing the degradation rate modeling of multicomponent municipal and industrial wastewaters. Furthermore, the requested instrument is valuable in the co-applicants' research programs to monitor total organic carbon and total nitrogen during the course of reactions that take place in wastewater treatment as well as biosolids remediation. Consequently, the TOC/TN analyzer is a key and critical piece of equipment for these research programs.
