ABSTRACT:
Silica gel is treated with a reactive phthalocyanine compound to form the blue silica gel, which has a phthalocyanine skeleton linked through an organic group. Typically, a phthalocyanine reactive dye is used for the reaction with silica gel at its hydroxyl or other reactive site. The blue silica gel easily adsorbs and desorbs the polycyclic organic substances in a solution. The blue silica gel can be used for the separation or removal of the mutagenic substances from the environment, foodstuffs, etc.
