Synthetic dyes are widely used in textile, food,
pharmaceutical and cosmetic industries and they have an
important place in our daily lives. In recent years toxic
effects of synthetic dyes on environment and human health
have been reported and natural dyes have been proposed as
an alternative colorants.Indirubin, 6-bromo indirubin, 6"-bromo indirubin, 6,6"-dibromo indirubin, indigotin, 6-bromo indigotin and 6,6"-dibromo indigotin are molluscan dyes. These dyes are the first known colorants in history and they have been used in many traditional medical prescription. Recently their new analogues have been tested in treatment of cancer, diabetes and Alzheimer"s diseases.
Mordanting process is very important in dyeing procedure. The interaction between mordant metal and dye is the most significant factor which is effecting the quality of the color. In this study we investigate the interaction of molluscan indigoid dyes with Al (III) and Sn (II) metals by spectrophotometric method.
