چکیده
|
The homogeneous oxidative photodegradation of basic violet 3 in presence of cu+/h2o2 is reported. the effects of operating variables such as ph, [h2o2], [cu+] and [dye] were maximized with the aid of box-behnken design. the dye removal was monitored by using uv-visible spectrophotometer, fourier transform infra-red spectroscopy (ftir) and total carbon analyzer. the degradation efficiency for basic violet (bv3) reached 99% and appreciable mineralization (70 %) was achieved. kinetic profiles show consistency with pseudo-first-order rate scheme. evidence for phenyl ring opening was corroborated by ftir spectroscopy. the cu(i) photo-fenton-like degradation is favored by increasing ph.
