Abstract

<p>Magnetite particles bearing covalently immobilized copper phthalocyanine dye ("blue magnetite") were prepared and used for the sorption of triphenylmethane dyes from aqueous solutions. The binding of some triphenylmethane dyes bearing two or three amino groups (basic fuchsin, crystal violet, malachite green) followed the Langmuir adsorption model. The maximum adsorption capacities were calculated. Dyes having no amino group in their molecules exhibited only low adsorption to immobilized copper phthalocyanine. The presence of amino groups in the molecules of triphenylmethane dyes seems to be necessary for their efficient binding on blue magnetite. Generally, efficient sorption of the organic compounds to immobilized copper phthalocyanine may be conditional on a cooperative effect of two parameters, viz. a certain planarity of the sorbate molecule and interaction of the central copper ion of the phthalocyanine molecule with the sorbate amino group or heterocyclic nitrogen atom.
