Concentration of nitrate, nitrite and fluoride in drinking water and bottled water in Semnan city
Introduction: The safety of drinking water is one of the critical indexes concerning to health and hygiene of a society. Monitoring and controlling qualitative indices of water is of great importance. Therefore, this study aimed to investigate the quality of bottled water and urban drinking water in Semnan city with regard to the concentration of pollutant ions of nitrite and nitrate as well as...
متن کاملKINETIC-SPECTROPHOTOMETRIC DETERMINATION OF TRACE AMOUNTS OF NITRITE BY THE REACTION OF METHYL ORANGE FORMATION
The composite diazotization coupling reaction of sulfanilic acid and N, Ndimethylaniline was used for the precise, accurate, and rapid determination of trace amounts of nitrite ion (0.02-3 µg/ml). The reaction was monitored spectrophotometrically by measuring the absorbance of the produced methyl orange at 510 nm by a fixed the method of 5.0 minutes. The relative standard deviation for the...
متن کاملInvestigation of Nitrate and Nitrite Concentration in Drinking Water of some Universities of Iran
Introduction: Water is vital for life. Its inadequate quality causes significant effects on the health condition of the individuals and society. Groundwater is one of the sources of Nitrate that level over standard limits may lead to several health problems such as hemoglobin metabolism and the formation of nitro amino compounds. Therefore, the aim of this study is determining ...
متن کاملDetermination of Pentachlorophenol in Drinking Water
Este trabalho relata um método envolvendo derivação in situ e extração para determinação de resíduos de PCP em amostras de água. O derivado acetilado de PCP é analisado por cromatografia a gás com detector por captura de elétrons. O limite de detecção do método é de 1 μg/L e sua eficiência é demonstrada pelos valores médios de recuperação (78-108%) estudados em três níveis de fortificação (2; 1...
متن کاملNitrate, Nitrite, and Ammonium Variability in Drinking Water Distribution Systems
Accurate assessments of exposure to nitrate in drinking water is a crucial part of epidemiological studies investigating long-term adverse human health effects. However, since drinking water nitrate measurements are usually collected for regulatory purposes, assumptions on (1) the intra-distribution system variability and (2) short-term (seasonal) concentration variability have to be made. We a...
