The Use of Chitosan as an Absorbent to Absorb Fe Ions and Turbidity in a Mixture of Detergent and Iron Solutions

Introduction

Chitosan, a polysaccharide derived from chitin, has gained significant attention in recent years due to its potential in overcoming environmental pollution. With the increasing presence of organic, inorganic, and heavy metals in ecosystems, the need for effective solutions to mitigate these pollutants has become a pressing concern. One of the strategies that have shown promise in reducing pollution is the use of chitosan as an adsorbent agent. Chitosan has been found to be effective in absorbing heavy metals, turbidity, dyes, and pesticides, making it a potential water purifier.

The Role of Chitosan in Absorbing Heavy Metals and Turbidity

Recent studies have demonstrated the effectiveness of chitosan in absorbing iron ions (Fe) and reducing turbidity in detergent solutions. The results of these studies have shown that a 1% chitosan solution can absorb around 88.09% of metal in a mixture of a solution containing 5 grams of detergent. This finding highlights the potential of chitosan in overcoming the problem of heavy metal pollution, particularly in conditions where detergents are commonly used in everyday life.

Optimum Conditions for the Use of Chitosan

Further analysis has revealed that the optimum condition for the use of chitosan in reducing turbidity in the detergent solution is at a dose of 10 grams of detergent. In this condition, the decrease in turbidity reached around 61.08%. This decline demonstrates the effectiveness of chitosan in acting as a cleaning agent, which can be an environmentally friendly alternative for wastewater treatment.

Benefits and Potential of Chitosan

Chitosan offers a range of benefits beyond its ability to absorb heavy metals. It is also used in the fields of health, agriculture, and the food industry. In the environmental context, chitosan can reduce the risk of pollution and help restore contaminated water quality. The use of chitosan is also in line with sustainable trends that are growing, where people are increasingly aware of the importance of protecting the ecosystem. By utilizing natural ingredients such as chitosan, we can not only clean up the environment, but also support efforts to reduce the use of hazardous chemicals that can worsen environmental conditions.

Applications of Chitosan

Chitosan has a wide range of applications, including:

Water Purification: Chitosan can be used to remove heavy metals, turbidity, and other pollutants from water, making it a potential solution for water purification.
Wastewater Treatment: Chitosan can be used to treat wastewater, reducing the risk of pollution and helping to restore contaminated water quality.
Health and Agriculture: Chitosan has been found to have potential applications in the fields of health and agriculture, including the development of new medicines and fertilizers.
Food Industry: Chitosan can be used in the food industry as a natural preservative and thickening agent.

Conclusion

The use of chitosan as an adsorbent shows very promising results in absorbing Fe ions and reducing turbidity in the detergent solution. With results that show high efficiency in absorbing heavy metals, chitosan can be an effective solution in overcoming pollution problems in the environment. Therefore, further research and development in the use of chitosan must be encouraged, so that we can find a better solution for the challenges of future environmental pollution.

Future Directions

Future research should focus on:

Scaling up the use of chitosan: Further research is needed to scale up the use of chitosan in real-world applications, including water purification and wastewater treatment.
Developing new applications: Chitosan has a wide range of potential applications, including health and agriculture. Further research is needed to develop new applications for chitosan.
Improving the efficiency of chitosan: Further research is needed to improve the efficiency of chitosan in absorbing heavy metals and reducing turbidity.
