Popis: | Pollution has become a great challenge for modern world. Hence, recycling trend is growing worldwide. Human hair, a fancy part of human body, creates a bulk of litter on trimming, yet has wide spectrum of applications. A facile thermal approach has been implemented in this research to synthesize carbon particles (CP) from waste human hair. CP surface analyses was made through SEM, ATR, TGA & Raman. Efficient adsorptive behavior of synthesized CP against Zn and Pb has been observed with 70% Pb (9.325mg/10mg CPs) and 90% Zn (37mg/10mg CPs) adsorption. The augmented adsorptive capacity of CP ultimately finds its application in heavy metal removal from waste water. Cyclic voltammetry (CV) justified outstanding adsorption behavior of CP by speedy electron transfer, better charge storage and swift ionic diffusion; with 53 mC current carrying capacity and 1.98 to 4.37 cm2 effective surface area. CV data has shown electrochemical reversibility and double layer capacitance. CP conductivity has been observed from 19.78 µS to 38.4 µS, with values between -17.4 mV and -28.6 mV. |
