The Use Of Nanopartikel Chitosan As An Adsorbent To Reduce Levels Of Fe, Zn And Cu Metals In Sibolga Rice
The use of nanopartikel chitosan as an adsorbent to reduce levels of Fe, Zn and Cu metals in Sibolga rice
Heavy metal pollution in rice is a pressing issue that poses a significant threat to human health. The accumulation of metals such as Fe, Zn, and Cu in the body can lead to various diseases, making it essential to find effective solutions to reduce their levels in rice. This study examines the potential of nanopartikel chitosan as an adsorbent to reduce heavy metals of Fe, Zn, and Cu in Sibolga rice.
Understanding the Problem of Heavy Metal Pollution in Rice
Heavy metal pollution in rice is a widespread issue that affects not only the quality of rice but also the health of consumers. Metals such as Fe, Zn, and Cu can accumulate in the body and cause various diseases, including cancer, neurological disorders, and reproductive problems. The use of chemical fertilizers and pesticides in agriculture has led to the contamination of soil and water, resulting in the accumulation of heavy metals in rice.
The Role of Nanopartikel Chitosan in Reducing Heavy Metal Levels
Chitosan nanoparticles have been shown to be effective in reducing heavy metal levels in rice. The process of making chitosan nanoparticles involves the dissolution of chitosan in a 1% acetic acid solution for 30 minutes. Then, 50 ml of nanoparticle chitosan solution is added to 100 ml of Sibolga rice sample. Analysis of metal content of Fe, Zn, and Cu is carried out using the atomic absorption spectrophotometer (SAA) method on the sample before and after treatment.
The Effectiveness of Nanopartikel Chitosan in Reducing Heavy Metal Levels
The results of this study showed that chitosan nanoparticles were able to absorb heavy metals with high success rates. Decreased levels of Zn metal reached 90.7279%, CU 96,2187%, and Fe 91,9894%. These results indicate that nanopartikel chitosan is a highly effective adsorbent in reducing heavy metal levels in rice.
Why is the Nanoparticle Chitosan Effective?
Chitosan nanoparticles have several advantages as adsorbents, including:
Large Surface Area: Small particle size allows chitosan nanoparticles to have a large surface area, thereby increasing its ability to bind heavy metals. Chemical Properties: Chitosan has a positive charged amino group, which can interact with negatively charged metal ions, so that heavy metals can be bound to the surface of chitosan. *Biodegradability: Chitosan is a natural ingredient that is environmentally friendly and easily decomposed, so it does not leave dangerous residues in rice.
The Importance of this Research
This study shows the great potential of the nanopartikel chitosan as a solution to overcome the problem of heavy metal pollution in rice. The use of chitosan nanoparticles can be an effective, safe, and environmentally friendly alternative to improve the quality of rice and maintain public health.
Next Steps
Further research is needed to optimize the use of chitosan nanoparticles as adsorbents, such as by exploring the influence of chitosan concentration and contact time on the efficiency of adsorption. It is also important to evaluate the impact of the use of nanopartikel chitosan on the quality and taste of rice.
Conclusion
The use of nanopartikel chitosan as an adsorbent to reduce heavy metal levels in Sibolga rice is a promising solution to overcome the problem of heavy metal pollution in rice. The effectiveness of chitosan nanoparticles in reducing heavy metal levels, combined with their biodegradability and environmental friendliness, make them an attractive alternative to traditional methods of reducing heavy metal levels in rice.
