REACTIVE BLACK 5 Usage And Synthesis
UsesC.I.Reactive Black 5 can be used for Ink jet recording apparatus and ink jet method reducing clogging during textile printing
UsesReactive Black 5 (RB5) has been:
  • used in an optimization study on the photocatalytic degradation of RB5 dye in synthetic greywater effluent (i.e. aqueous RB5 in distilled water), in order to understand the effects of different photoreactor parameters on the degradation kinetics.
  • as a textile dye to investigate the anaerobic reduction in upflow stirred packed-bed reactors (USPBRs) with biological activated carbon (BAC) system
  • used in the performance evaluation of dye removal forlarge molecule substance

DefinitionChEBI: A bis(azo) compound with two aryldiazenyl moieties placed at positions 2 and 7 of a multi-substituted naphthalene.
General DescriptionReactive Black 5 belongs to the class of textile azo dyes. It can be biodegraded by the laccase enzyme in Ganoderma lucidum.
