Seems a bit odd why colour determines if it is absorved or not, doesn't it? My teacher could not answer this question.
Activated carbon has a highly porous structure with a large surface area, which allows it to attract and trap molecules of various sizes and shapes. The carbon also has a slightly negative charge, which makes it attractive to positively charged particles. This combination of properties allows activated carbon to effectively absorb colored particles.
Activated carbon is made from carbon-rich materials, such as coal, wood, or coconut shells, that have been treated with heat and chemicals to create a highly porous structure. This porous structure is what makes activated carbon different from other types of carbon, as it provides a larger surface area for adsorption.
Activated carbon can absorb a wide range of colored particles, including organic compounds, heavy metals, and dyes. It is also effective at removing odors and flavors from substances, making it a popular choice for water and air filtration systems.
The color of a substance can provide important information about its chemical composition. Certain colors may indicate the presence of specific molecules, which can then be targeted by activated carbon for adsorption. In addition, the color of a substance can also affect its taste, smell, and overall quality, making it important to remove colored particles for practical and aesthetic reasons.
The size of activated carbon particles can impact its adsorption capacity. Smaller particles have a larger surface area and can therefore adsorb more particles, but they may also clog more easily. Larger particles may have a lower surface area, but they can be more durable and have a longer lifespan. The size of activated carbon particles should be chosen based on the specific application and the types of particles that need to be removed.
