Efficient degradation of organic dyes by heterogeneous cefdinir derived silver nanocatalyst
Muhammad Safdar,Yasmeen Junejo,Aamna Balouch 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.31 No.-
Cefdinir derived silver nanocatalyst (Cef-Ag (0) NPs) was successfully synthesized in aqueous solution byefficient one-pot method and effectively employed for the ultrafast catalytic degradation of Rose Bengaland Eosin Gelblich dyes. The improvement was achieved in percent degradation of toxic dyes by varyingand optimizing reaction time, and amount of catalyst reducing agent concentration. The catalytic studyrevealed that complete reduction 99.9% of dye was accomplished in short period of reaction time (60 s)by efficient cefdinir derived silver nanoparticles. The calculated K (rate constant) value for RB and EGcatalytic degradation was achieved 7 10 2 and 10 10 2 s 1, respectively by plotting lnC vs time (s)and result show that reaction is following first order kinetics.
