Nitrogen compounds were the main contaminants in natural water, and the measurement and on-site automatic monitoring of total nitrogen in lakes and rivers which might be polluted by nitrogen were the important tasks for environmental engineers. A new and rapid instrumental technique has been developed to measure organic and inorganic nitrogen compounds in both ground water and contaminated source...
The measurement and monitoring of total nitrogen (TN) in water and wastewater were important tasks for environmental engineers, but the key challenge was how to use the technologies in on-line water detection and monitoring. A new method was established according to the improvement of general method which measured total nitrogen in two wavelengths (220 nm and 275 nm). The nitrogenous compounds of...
