Characterization and Selection by Optical Absorption and Emission Spectrophotometry of a Series of Red Dyes Capable of Destroying Far UV Rays by Absorption

The far ultraviolet rays are harmful to human health, particularly for their mutagenic effects; it can cause skin cancer, cataracts, photochemical pollution. In the future, chemists plan use as weapons destruction of objects. Therefore, we should meet this future challenge by scientific means in order snuff out its far-ultraviolet rays. paper, we’ve intend carry a deep spectral study on series red dyes such as: beet red; congo methyl neutral phenol and carminic acid, find which able damage absorption. experimental results have been carried our laboratory; has shown that certain pigments an ability absorb light range due chemical structures. they dodging Moreover, analyzes emission studied, showed these emit beyond 600 nm.
