Potentiality of spent tea waste charcoal has been determined as low cost adsorbent for the removal of heavy metals (Nickel and Chromium) from the waste water with the three fold objective of solid waste management for effective and green treatment of heavy metals’ highly contaminated effluent.
Iron nanoparticles doped tea waste charcoal (Fe-TWC) was synthesized and characterized using powder XRD, SEM and EDX. Synthesized Fe-TWC was found quite effective in removing high concentrations of Ni (II) and Cr (VI) from the simulated samples as well as actual industrial samples.
Adsorption data follows Langmuir adsorption and pseudo-second order kinetic model for both the metals. Thermodynamic parameters have also been assessed.
This study indicated that Fe-TWC can be used as an effective, low cost and environment friendly adsorbent for the treatment of electroplating waste effluent.
