Description

Direct Red 31 is a dye that is used in wastewater treatment. The dye has shown to be able to absorb light at an optimum wavelength of 543 nm, which is the wavelength of light that penetrates water more deeply than other wavelengths. Direct Red 31 has been shown to be effective in a variety of biological treatments, such as those involving activated sludge or trickling filters. This dye is also reactive and can form covalent bonds with organic molecules like fatty acids, leading to increased adsorption on the surface of particles. Additionally, this dye has high chemical stability and can withstand temperatures up to 230 degrees Celsius.
