Study of the Sensitivity of the Atomic Absorption Spectrophotometer (SSA) Vapour Hydride Generation Accessories (VGHA) Technique Compared to the SSA on the Analysis of the Arsenic Element (US) Found in Drinking Water

Introduction

The quality of drinking water is a critical factor in maintaining public health. The presence of toxic elements such as Arsenic (US) in drinking water can have severe health consequences. Therefore, it is essential to develop reliable analytical techniques for detecting US in drinking water. The Atomic Absorption Spectrophotometer (SSA) is a widely used analytical tool for measuring metal concentrations in samples. However, its sensitivity can be improved by combining it with the Vapour Hydride Generation Accessories (VGHA) technique. This study aims to compare the performance of the SSA VGHA technique with the conventional SSA method on the analysis of US in drinking water samples from Tirtanadi Regional Water Supply Companies (PDAM).

Background

The SSA is a reliable analytical tool for measuring metal concentrations in samples. However, its sensitivity can be limited, especially when detecting elements at very low concentrations. The VGHA technique is a modification of the SSA that uses a hydride generation system to increase the sensitivity of the instrument. This technique has been shown to be effective in detecting elements such as US, which is a common contaminant in drinking water.

Methodology

This study was conducted to compare the performance of the SSA VGHA technique with the conventional SSA method on the analysis of US in drinking water samples from PDAM. Sampling was carried out at three points, namely the Sunggal Water Treatment Plant (IPA) and the well in the Simalingkar Booster, for three months, from March to May 2009. The SSA VGHA technique was used to analyze the US concentration in the drinking water samples, while the conventional SSA method was used as a control.

Results

The results of this study showed a significant increase in the absorption results using the SSA VGHA technique compared to the conventional SSA method. The US concentration in the Sunggal Natural Sciences was detected at 8,8018 PPB, 9,3429 PPB, and 9,0337 PPB alternately, while in the well in the Simalingkar Booster detected 8,8459 PPB, 8,9895 PPB, and 8,5699 PPB. This increase reached 10,429.8 times compared to the SSA Method.

Discussion

The results of this study show that the SSA VGHA technique is very effective in US analysis of drinking water. The US concentration detected in both water storage locations meets the standards set in the Decree of the Minister of Health of the Republic of Indonesia Number 907/Menkes/VII/2002, which sets US safe limits in drinking water. The SSA VGHA technique offers several advantages in US analysis of drinking water, including high sensitivity, accuracy, and precision.

Advantages of SSA VGHA Technique

The SSA VGHA technique offers several advantages in US analysis of drinking water, including:

*** High Sensitivity: ** The SSA VGHA method allows US detection at very low concentrations, so it is more effective in identifying US contamination in drinking water, even in small amounts. *** Accuracy and Precision: ** This method produces accurate and precise data, increasing the reliability of the results of the analysis and supports appropriate decision making related to the safety of drinking water. *** Efficiency: ** The use of SSA VGHA can save time and cost of analysis compared to conventional methods, increase the efficiency of the analysis process.

Conclusion

This study shows the great potential of SSA VGHA techniques in US analysis of drinking water. With high sensitivity, accuracy, and efficiency, it has, this method can be an important tool in maintaining the safety and quality of drinking water, supporting public health. The SSA VGHA technique can be used as a reliable analytical tool for detecting US in drinking water, and its use can help to ensure the safety of drinking water for the public.
