Structural, morphological, and optical properties of country egg shell derived activated carbon for dye removal

Abstract

Abstract Country egg shell (CES-AC) derived activated carbon was successfully investigated using simple chemical activation process. Investigated novel CES based activated carbon was characterized using XRD, FT-IR, DLS, SEM and Photo catalytic activity. XRD pattern exposes crystalline nature and displays hexagonal graphic structure of carbon. Using FT-IR the functional group present in the activated carbon was identified. SEM image reveals irregular activated carbon structure. Irregular shape due to amorphous carbon. Average particle size value of activated carbon from DLS Spectra shows 159 nm. Photo degradation of Methylene blue using UV–Visible irradiation technique. Catalytic activity was recorded with regular time interval from 0 to 120 min. Activated carbon results in maximum degradation efficiency of about 73% at the end of 2 h. Methylene blue is converted to Leuco methylene blue during the degradation process. Degradation efficiency increases with increased reaction time. Thus the activated carbon investigated is highly applicable for waste water treatment and organic dyes, industrial and textile water degradation.
