Journal of Chemical Technology & Biotechnology > 99 > 5 > 1027 - 1055

Crystal violet (CV), a cationic dye, has been demonstrated to be a powerful carcinogen, a mitotic toxin and poisonous to mammalian cells such that the predominant presence of the dye invariably causes several effects of destruction to mankind and it necessitates a clarion call to do away with this nuisance before it can produce a snowball effect. The recent widespread reporting of the photocatalysis‐mediated...
