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.

需要资金购买一台“总有机碳/总氮分析仪”。所要求的仪器是基于燃烧的总有机/无机碳以及总氮分析仪，配有自动进样器。所要求的TOC/TN分析仪将支持消失和动力学速率模型的开发，监测废水中母体污染物及其中间体的降解，以及优化工业和城市废水处理的光化学和生物组合工艺。TOC/TN分析仪的主要用途是通过确定光化学和生物反应过程中使用的总有机碳和总氮的可靠数据来确定光化学和生物降解速率。工业废水经高级氧化技术和生物处理后，其母体化合物可能消失，但系统中仍存在许多其他有机和无机化合物。这是由于这些反应产生了中间体。多组分体系的动力学模型不仅复杂，而且如果不考虑反应过程中的所有中间体，可能会不准确。由于生物需氧量（BOD）、化学氧化需氧量（COD）和其他特定化合物消失的限制和缺点，通常难以为每个样品产生足够可靠的数据点以用于良好的动力学参数估计。因此，总的有机/无机碳和氮平衡是必要的，在开发多组分城市和工业废水的降解速率建模。此外，所要求的仪器在共同申请人的研究计划中是有价值的，以在废水处理以及生物固体修复中发生的反应过程中监测总有机碳和总氮。因此，TOC/TN分析仪是这些研究项目的关键和关键设备。
