The Use of Nanoparticles Chitosan from Squid Cartilage (Loligo pealli) as Adsorbents to Iron Metal Ions (Fe3+), Zinc (Zn2+), and Cadmium (CD2+)

Introduction

The increasing levels of heavy metal pollution in water bodies pose a significant threat to human health and the environment. Heavy metals such as iron (Fe3+), zinc (Zn2+), and cadmium (CD2+) are among the most common pollutants found in water bodies. The development of effective adsorption technology is crucial to reduce the concentration of these heavy metal ions in water bodies. In this study, we discuss the use of nanoparticles chitosan originating from squid cartilage (Loligo pealli) as an adsorbent to reduce the concentration of heavy metal ions.

Production of Nanoparticles Chitosan

The production of nanoparticles chitosan involves dissolving chitosan in a 1% acetic acid solution, followed by the addition of a 1% sodium tripolifosphate solution to an emulsion. The emulsion is then placed in an ultrasonic bath for one hour to produce chitosan nanoparticles. The resulting nanoparticles have a high specific surface area and binding power, making them effective adsorbents for heavy metal ions.

Adsorption Process

The adsorption process involves mixing 50 ml of the nanoparticles produced with 100 ml of standard solutions of metal ions Fe3+, Zn2+, and CD2+ with a concentration of 5 mg/l. The adsorption process is carried out with a variation of contact time for 15, 30, and 45 minutes. The efficiency of reducing metal content is determined using atomic absorption spectrophotometer (AAS).

Results and Discussion

The results showed that the adsorption process could reduce metal levels with the percentage absorption of Fe metals reaching 86.796%, Zn 93.097% metal, and CD metal 89.724% during optimum contact time for 30 minutes. The high percentage of absorption indicates that chitosan nanoparticles are very effective in capturing heavy metal ions from the solution. This process not only reduces heavy metal pollution but can also be used in wider water treatment applications.

Additional Analysis and Explanation

Chitosan is a natural polymer that has biodegradable and non-toxic properties, making it suitable for environmental applications, especially in wastewater treatment. The use of nanoparticles chitosan from natural sources, such as squid cartilage, provides added value in terms of sustainability and waste reduction. Nanoparticle chitosan production process using acetic acid solution and sodium tripolifosphate helps increase the specific surface and powers of chitosan binding to heavy metal ions.

Heavy metal ions, such as Fe3+, Zn2+, and CD2+, are contaminants that are harmful to human health and the environment. Therefore, the development of effective adsorption technology is very important. The results showed a high percentage of absorption at contact time of 30 minutes indicated that chitosan nanoparticles were very effective in capturing heavy metal ions from the solution. This process not only reduces heavy metal pollution, but can also be used in wider water treatment applications.

Methodology and Future Research Directions

The methodology used in this study provides a better understanding of the interaction between chitosan nanoparticles and metal ions, which can be the basis for further research. Similar research can be carried out with parameter variations, such as the pH of the solution and the initial concentration of metal ions, to explore the potential use of nanoparticles chitosan in more complex wastewater treatment.

Conclusion

With the increase in awareness of the importance of sustainability and the environment, research on the use of natural resources to overcome the problem of heavy metal pollution is increasingly relevant. Nanoparticles chitosan from squid cartilage offers innovative solutions that are not only effective, but also environmentally friendly in combating water pollution.

Recommendations

Based on the results of this study, we recommend the use of nanoparticles chitosan from squid cartilage as an effective adsorbent for heavy metal ions in water bodies. The use of natural resources, such as squid cartilage, provides added value in terms of sustainability and waste reduction. Further research is needed to explore the potential use of nanoparticles chitosan in more complex wastewater treatment applications.

Limitations and Future Research Directions

This study has some limitations, such as the use of a single type of metal ion and the lack of variation in the pH of the solution. Future research should aim to explore the potential use of nanoparticles chitosan in more complex wastewater treatment applications, such as the treatment of wastewater from industrial processes.

Conclusion

In conclusion, this study demonstrates the effectiveness of nanoparticles chitosan from squid cartilage as an adsorbent for heavy metal ions in water bodies. The use of natural resources, such as squid cartilage, provides added value in terms of sustainability and waste reduction. Further research is needed to explore the potential use of nanoparticles chitosan in more complex wastewater treatment applications.
