Determination Of Calcium (Ca) And Iron (Fe) Content In Liquid Waste Of IPAL Kabanjahe Hospital

Introduction

The management of liquid waste from hospitals is a critical aspect of maintaining environmental sustainability. The Wastewater Treatment Plant (IPAL) of the Kabanjahe General Hospital is responsible for treating liquid waste generated from various sources within the hospital. However, the quality of the treated waste is a concern, as it can affect the water quality of the receiving environment. This study aims to determine the levels of calcium (Ca) and iron (Fe) in liquid waste from the IPAL Kabanjahe Hospital, with a focus on the impact of chlorine addition on these levels.

Methodology

The analysis of calcium and iron levels in liquid waste was carried out using the atomic absorption spectrophotometry (AAS) method. AAS is a widely used chemical analysis technique for measuring the concentration of elements in a solution. The method involves the absorption of light by the atoms of the element being analyzed, which is directly proportional to the concentration of the element in the solution.

Results and Discussion

The results of the analysis are presented in the following table:

The results show that the addition of chlorine to the liquid waste significantly affects the levels of calcium and iron. The calcium levels in liquid waste without chlorine are found to be 0.0585 mg/l, whereas in liquid waste containing chlorine, the levels are lower, at 0.0411 mg/l. This suggests that the addition of chlorine can reduce the levels of calcium in liquid waste.

On the other hand, the iron content in liquid waste without chlorine is very low, at 0.0017 mg/l. However, when chlorine is added, the iron content increases significantly to 0.0501 mg/l. This increase in iron levels may be caused by chemical reactions that occur between chlorine and compounds in the waste, which causes the release of iron into the solution.

Implications for Waste Management

The results of this study have important implications for the management of liquid waste in the Kabanjahe Hospital. The measured levels of calcium and iron can affect the water quality of the treated waste and its feasibility to be discharged into the environment. Therefore, it is essential for the hospital to continue to monitor and control the heavy metal content in its waste.

Environmental Implications

From an environmental perspective, liquid waste containing high levels of calcium and iron can pose a risk of pollution for the water body around. Calcium, although essential for life, can cause a buildup of minerals if the concentration is excessive, while high amounts of iron can have the potential to be toxic to the aquatic ecosystem. Therefore, further research and control of waste quality are crucial to maintain environmental sustainability.

Conclusion

In conclusion, the determination of calcium and iron content in the liquid waste of IPAL Kabanjahe Hospital revealed a significant difference between waste with and without chlorine. This shows the need for more attention in waste management to prevent negative impacts on the environment. This knowledge is important not only for hospitals but also for those involved in environmental management and research.
