Effect Of Effectiveness Of Carbon Pineapple Crown Leaves As Adsorbents On Decreased Levels Of Cadmium Metals (CDs) And Manganese (MN) In Drilling Well Water
Introduction
The increasing levels of heavy metals in well water pose a significant threat to human health and the environment. Cadmium (CD) and Manganese (MN) are two of the most common heavy metals found in well water, which can cause serious health problems if ingested. In this study, we aim to evaluate the effectiveness of activated carbon from pineapple crown leaves as an adsorbent to reduce the levels of CD and MN in drilling well water.
Background
Activated carbon is a widely used adsorbent to remove metal ions from water. However, traditional activated carbon is often derived from non-renewable sources, such as coal and petroleum. In recent years, there has been a growing interest in using renewable and sustainable materials as adsorbents. Pineapple crown leaves, a by-product of pineapple production, are an abundant and affordable lignocellulose material that can be used to produce activated carbon.
Methodology
In this study, we used activated carbon from pineapple crown leaves that were activated with 9% NaOH. The activated carbon was tested using X-Ray Diffraction (XRD) to determine its crystalline structure. Water samples were collected from residents' wells in Sigara-Gara Hamlet III, Patumbak District, Deli Serdang Regency. The water samples were treated with HNO3 to pH less than 2 and then destroyed. The concentrations of CD and MN were determined before and after the addition of activated carbon from pineapple crown leaves using atomic absorption spectrophotometer (AAS).
Results
The results showed a significant decrease in the concentrations of CD and MN in the wellbore well water after the addition of activated carbon from pineapple crown leaves. The percentage decrease in CD levels was 83.52%, 86.36%, 88.63%, 89.77%, and 90.34% for mass variations of 1, 2, 3, 4, and 5 grams, respectively. The percentage decrease in MN levels was 95.96%, 96.64%, 96.99%, 97.02%, and 97.10% for mass variations of 1, 2, 3, 4, and 5 grams, respectively.
Discussion
The effectiveness of activated carbon in absorbing heavy metals in well water is influenced by several factors, including surface area, porosity properties, and surface reactivity. The high porosity of activated carbon from pineapple crown leaves allows for good absorption of metal ions. The process of activation with NaOH increases porosity and facilitates chemical reactions between activated carbon and metal ions in water, thereby increasing the efficiency of adsorption.
Conclusion
The results of this study demonstrate the effectiveness of activated carbon from pineapple crown leaves as an adsorbent to reduce the levels of CD and MN in drilling well water. This study contributes to the science and technology of water treatment and provides practical solutions that are beneficial to the community. The use of renewable and affordable materials such as pineapple crown leaves has the potential to support sustainable resource management and improve the quality of water.
Recommendations
Further research can be done to explore the effectiveness of activated carbon from pineapple crown leaves in absorbing other heavy metals and to study the process of activated carbon regeneration after use. With this approach, we can improve the quality of water and maintain the health of the community around water sources.
Future Directions
The use of activated carbon from pineapple crown leaves as an adsorbent has the potential to be scaled up for industrial applications. Further research is needed to optimize the production process and to evaluate the long-term effectiveness of this adsorbent. Additionally, the use of other lignocellulose materials as adsorbents can be explored to provide alternative solutions for water treatment.
Limitations
This study has several limitations. The sample size was limited to water samples collected from residents' wells in Sigara-Gara Hamlet III, Patumbak District, Deli Serdang Regency. Further research is needed to evaluate the effectiveness of activated carbon from pineapple crown leaves in other locations and to determine the optimal dosage of activated carbon for different types of water.
Conclusion
In conclusion, this study demonstrates the effectiveness of activated carbon from pineapple crown leaves as an adsorbent to reduce the levels of CD and MN in drilling well water. The use of renewable and affordable materials such as pineapple crown leaves has the potential to support sustainable resource management and improve the quality of water. Further research is needed to explore the effectiveness of this adsorbent in other applications and to optimize the production process.
