Resumo: The aim of this research was to verify the use of Ultraviolet Spectrophotometric Screening Method on the analysis of nitrate-nitrogen in domestic wastewater samples, which is a method recommended to water samples with low organic matter contents. In order to do that, the results achieved with the aforementioned method were compared to the salicylate method that is largely used worldwide. The results observed from both methods were different according to Man-Whitney test (? = 5%). Nevertheless, such difference between them were less than 0,25 mg L-1 for half of the samples. Hence, the adoption of the UV spectrophotometric screening method to perform nitrate analyses on domestic wastewater samples seemed quite reasonable.

Hence, the adoption of the UV spectrophotometric screening method to perform nitrate analyses on domestic wastewater samples seemed quite reasonable.The objective of this study was to observe the feasibility of using the UV spectrophotometric method of the second derivative in the determination of nitrogen in the form of nitrate in sanitary sewers, since this method is indicated for water with low content of organic matter. Therefore, the results obtained in that method were compared with the salicylate methodology. The Mann-Whitney test showed a significant difference (? = 5%) between the results obtained in both methods. However, when compared, the difference between them was less than 0.25 mg L-1 in half of the observations. Despite this significant difference, the use of the second derivative method for sanitary sewage samples showed satisfactory performance.Universidade Federal de Viçosa - UFV2020-12-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/1158010.13083/reveng.v29i1.11580Engineering in Agriculture; Vol. 28 No. Contínua (2020); 579-583Revista Engenharia na Agricultura - REVENG; v. 28 n.
