Abstract
The amount of toxic pollutant is increasing day by day to an alarming level. This demands a facile and economical way to degrade those deadly contaminants. This study
provides a valuable and facile pathway to purify waste water from toxic dyes with a cheap and environmentally friendly approach. Cobalt ferrites doped with nickel were
synthesized employing the coprecipitation technique. In this research, varying concentrations of nickel (2%, 4%, 6%, 8%, and 10%) were incorporated into the cobalt
ferrite samples. Composites of these nickel doped ferrites with polyaniline were obtained by stirring the ferrites and polyaniline in distilled water as suspension followed
by sonication for one hour. The suspension was filtered, vacuumed dried and characterized using SEM with EDX, FTIR and XRD. Prepared nickel doped cobalt ferrites polyaniline composites degradation percentage was calculated via UV- Visible spectroscopy which indicated the degradation capacity was increased via increased percentage of nickel metal. Prepared nickel doped cobalt ferrite polyaniline composite degradation percentage was calculated via UV-Visible spectroscopy which indicated the degradation capacity was increased via increased percentage of nickel metal. The FTIR spectra confirmed the successful integration of nickel onto the surface of PANI. XRD spectra indicated the formation of a single-phase spherical structure. SEM analysis coupled with EDX revealed that the synthesized nanoparticles were uniformly dispersed and spherical, with their diameter increasing as a result of nickel doping. In summary, this study suggests that nickel-doped cobalt ferrite nano composites with PANI could serve as promising candidates for efficiently degrading toxic waste in wastewater. This efficiency is attributed to the incorporation of polyaniline into nickeldoped cobalt ferrites, making the approach sustainable and environmentally friendly.
