Beschreibung

Direct Red 28 is a dye that can be used in wastewater treatment. It can be adsorbed onto activated sludge, which reduces the amount of sludge needing to be treated. Direct Red 28 reacts with hydrogen peroxide to form a fluorescent derivative that has antimicrobial properties. Direct Red 28 also has been shown to have an effect on the enzyme activities of kidney bean extract and to inhibit the growth of bacteria in model systems. This dye is not toxic for body formation. However, it can react with potassium dichromate and hl-60 cells, which may lead to side effects such as skin irritation.
