Influence of microwave irradiation on hypochlorite decolorisation of synthetic dyes

Abstract

In this study three synthetic dyes were treated using hypochlorite or combination of hypochlorite and microwave irradiation in order to investigate factors which determine decolorisation of the investigated compounds. An azo dye (C.I. Reactive Orange 16 - RO16), an azo methine dye (C.I. Basic Yellow 28 - BY28) and an antraquinone dye (C.I. Acid Blue 111 - AB111) were used for experiments. Hypochlorite stability as well as the influence of microwaves on hypochlorite stability was also investigated.

U okviru rada, tri sintetske boje tretirane su rastvorom hipohlorita ili kombinacijom rastvora hipohlorita i mikrotalasnog zračenja, da bi se ispitao uticaj različitih faktora na obezbojavanje ispitivanih boja. Jedinjenja koja su korišćena u ispitivanju pripadaju azo (C.I. Reactive orange 16 - RO16), azometinskim (C.I. Basic yellow 28 - BY28) i antrahinonskim bojama (C.I. Acid Blue 111 - AB111). takođe je ispitivana stabilnost hipohlorita kako pri zagrevanju tako i pri mikrotalasnom zračenju.
