UV-Visible Spectrophotometry Method

The UV-Visible spectrophotometry method is one of the analytical techniques that is widely used in the measurement of the concentration of chemical compounds in the solution. This technique works by measuring the absorbance of light at a certain wavelength, which is correlated with the concentration of these compounds in the sample. The advantage of this method lies in its ability to provide fast and accurate results, as well as ease of use. The UV-Visible spectrophotometry method is a reliable and efficient method for analyzing nitrite levels in groundwater.

Methodology

The research on nitrite levels (NO₂-) in groundwater in Tandem Village was carried out in the Laboratory of the North Sumatra Energy and Mineral Resources. The method used in this analysis is ultraviolet-visible spectrophotometry at a wavelength of 543 Nm. The samples were collected from the groundwater sources in Tandem Village and analyzed using the UV-Visible spectrophotometry method. The results of the analysis were then compared with the established quality standards to determine the level of nitrite pollution in the groundwater.

Results

The results of the analysis showed that nitrite content in groundwater in Tandem Village reached 0.287 mg/L. This level is still below the threshold set by the Regulation of the Minister of Health of the Republic of Indonesia, which states that the level of nitrite that is safe for drinking water is under 1 mg/l. This finding is very significant because it shows that groundwater in the area is relatively safe for consumption, thus providing health insurance for the local community.

Discussion

The results of the analysis of nitrite content in groundwater in Tandem Village show that the level of nitrite pollution is within safe limits. This research not only provides relevant data to the local community, but also contributes to environmental protection and public health efforts.
