Introduction

Carbon monoxide (CO) is one of the most significant pollutants produced from motor vehicle emissions, posing a serious threat to human health. The gas binds hemoglobin in the blood, reducing the capacity of blood to transport oxygen, which can lead to severe health consequences. In light of the dangers caused by CO gas, it is essential to implement measures to control emissions from motorized vehicles. One innovative solution that can be applied is the use of lignin as an air filter, fabricated using the electrospinning method.

The Electrospinning Method: A Technique for Producing Nanometer Fibers

The electrospinning method is a technique used to produce nanometer fibers from polymer solutions. In this context, lignin combined with polyethylen oxide (PEO) is the primary material for making air filters. The fabrication process produces porous fibers that function as adsorbents, capable of absorbing various pollutants, including carbon monoxide. The fibers produced not only have a high absorption capability but also a large surface area, thereby increasing their effectiveness in filtering harmful gas emissions.

Characterization of Lignin/PEO Solutions

In this study, lignin/PEO solutions were analyzed through viscosity and conductivity testing. Further characterization of nanoserate lignin/PEO was done using Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), and CO gas emission testing. The results of morphological analysis show that the increase in lignin weight ratio (6:15) is directly proportional to the efficiency of CO gas adsorption. The diameter of the resulting nanoserate ranges from 50 to 300 nanometers, which contributes to filtration power reaching 88.8% of the total CO gas emissions tested.

The Influence of Fiber Diameter on CO Gas Absorption

The diameter of the lignin fiber as an adsorbent is very influential on the CO gas absorption process. This is because the larger surface area is directly proportional to the rate of gas absorption. The test shows that fibers with smaller diameters not only increase the efficiency of gas absorption but also support the higher conductivity value, ranging from 45.5 to 61.2 ms/cm, and viscosity between 1790 to 621 MPas. Both of these parameters indicate that the lignin/PEO solution has physical properties that support the ideal formation of fiber for air filtering.

The Potential of Lignin as a Raw Material for Air Filter Fabrication

Overall, the use of lignin as a raw material for air filter fabrication through the electrospinning method offers a significant potential in overcoming the problem of carbon monoxide gas emissions. With the increasing efficiency of adsorption, this innovation can contribute to improvement of air quality and public health, as well as an important step towards a cleaner and sustainable environment.

Conclusion

In conclusion, the fabrication of lignin/PEO with the electrospinning method as a filter for carbon monoxide gas emissions is a promising innovation that can contribute to the improvement of air quality and public health. The use of lignin as a raw material for air filter fabrication offers a significant potential in overcoming the problem of carbon monoxide gas emissions.
