The Nature Of The Kitosan/Al2O3 Film -based Sensor In Detecting The Concentration Of Urea Fertilizer
Introduction
The accurate monitoring of fertilizer concentration is crucial in agriculture to improve output and reduce the negative impact on the environment. Recent research has focused on the development of sensors that can detect the concentration of urea fertilizer. One such sensor is the chitosan/Al2O3 film-based sensor, which has been successfully fabricated using the electrodeposition method. This study aims to investigate the nature of the chitosan/Al2O3 film-based sensor in detecting the concentration of urea fertilizer.
Fabrication of Chitosan/Al2O3 Film-Based Sensor
The fabrication of the chitosan/Al2O3 film-based sensor involved mixing chitosan with various amounts of Al2O3, namely 0.01 g, 0.02 g, 0.03 g, 0.04 g, and 0.05 g. The resulting sensor was then tested to detect the concentration of urea fertilizer in a solution with varying concentrations of 10 ppm, 20 ppm, 30 ppm, 40 ppm, and 50 ppm. The test results showed that the chitosan/Al2O3 sensor reached a maximum output voltage of 0.4243 V when detecting urea.
Effect of Al2O3 Addition on Sensor Performance
Further analysis revealed that the addition of Al2O3 had a positive influence on the sensor's performance. In this experiment, sensors with an additional 0.03 g Al2O3 proved to be the best variation. This sensor showed good sensitivity and reproducibility, as well as a longer lifespan compared to other variations. Additionally, the surface of the film sensor with an additional 0.03 g Al2O3 was more evenly distributed, which contributed to improving sensor performance.
Characterization of Film Using Fourier Transform Infrared Spectroscopy (FT-IR)
The characterization of the film was done using FT-IR, which helped in understanding the chemical interactions between chitosan and Al2O3. The FT-IR results showed that there was an interaction between the two materials, which had the potential to increase the ability of sensors in detecting urea. This interaction can increase the active surface area available to interact with urea molecules, thereby increasing sensor sensitivity.
Importance of Research
The importance of this research lies in the potential application in the field of agriculture, where monitoring the concentration of urea fertilizer accurately is very important to improve agricultural output and reduce the negative impact on the environment. The chitosan/Al2O3-based sensor developed has advantages, such as the sustainability of chitosan material derived from natural resources, and the ability of Al2O3 to improve the physical and chemical properties of sensors.
Conclusion
The development of the chitosan/Al2O3 sensor is a step forward in sensor technology that is environmentally friendly and efficient. With further research, it is expected that this sensor can be optimized for practical use in monitoring fertilizer in agricultural land, so that it can provide greater benefits for farmers and environmental sustainability.
