Electrolyte assisted sono-electrochemical decomposition of reactive red 195

Untreated textile wastewater causes serious environmental impacts due to the presence of unfixed dyes. a commonly used reactive red (rr) 195 dye is significantly discharged in textile effluents thus enhancing water pollution. therefore,the current research was conducted for the treatment of reactive dye rr 195 by electrolyte assisted electrochemical process at various process conditions i.e,initial dye concentrations,ph,and concentration of supporting electrolyte (nacl). the decomposition of dye and color removal was analyzed using uv-vis spectrophotometer. the results indicated that ph and nacl were playing an important role in the degradation of rr 195. it was observed that 95.4% of dye was decomposed using 1.5g/l nacl at ph 3 after 25 min. kinetics studies showed that degradation of rr195 apparently followed second order reaction. the electrical energy consumption was found to be 6.11 whm -3 for dye effluent at 100 am-2 current density. for the justification of findings in experimental results bayesian regression analysis was used to determine the effect of nacl,ph and dye concentration on degeneration of rr195. it was observed that nacl had positive impact whereas ph and dye concentration had negative impact on degeneration of rr195.
