Mercury (II) Ions Assessment as a Toxic Waste Hazard in Solution Based on Imagery Data for a Part of Environmental Disaster Management

It has been made and calibrated a device to detect dissolved mercury (II) ions as a toxic hazard using Arduino Uno and color sensor TCS3200. The purpose of this design was to realize a device for detecting dissolved mercury (II) ions as heavy metal pollution based on the relation of soluble mercury ion concentration to the liquid from the imagery data. Conjoint natural and technological disasters like the Mercury may pose tremendous risks to regions which are unprepared for such disasters. The results could be an environmental disaster, particularly when these occur in a highly populated area. Controlling the levels of dissolved mercury ions on a regular basis is a part of the environmental disaster management. The device works by converting any light by the photodiode optical sensor when the output is such a magnitude of an electrical current which proportional to the received light color level. The currents that are processed using the Arduino IDE software to extract the RGB values of the dissolved mercury (II) ions image data. Dissolved mercury ions generally do not have the necessary color, therefore, biocatalyst as reagents to generate color in a solution containing the mercury and this study using the Silver Nanoparticles. After reacted with a solution of known concentration of mercury in the value of the solution then carried out on a sample data collection to determine the RGB color values in the solution. In general, the device can be used as a color calibrator applied to the detection of dissolved mercury (II) ions by the obtained image data.
