Biochar, defined simply as charcoal prepared by pyrolysis of agricultural waste (Biomass), was investigated as a low cost adsorbent for wastewater dye removal. The adsorption of textile D-Yellow dye from aqueous solution was carried out using cotton stalk bio-char (charcoal) as an adsorbent. The effects of different operating parameters such as initial dye concentration, amount of adsorbent (Biochar) and time of adsorption on removal of dyes were investigated. For this, liquid phase adsorption experiments were conducted in batch adsorption mode. The adsorption isotherm was developed for the effect of initial concentration of dyes. It was observed that rate of adsorption of dyes on biochar increases with increase in initial concentration of dyes.

Abstract


Biochar, defined simply as charcoal prepared by pyrolysis of agricultural waste (Biomass), was investigated as a low cost adsorbent for wastewater dye removal. The adsorption of textile D-Yellow dye from aqueous solution was carried out using cotton stalk bio-char (charcoal) as an adsorbent. The effects of different operating parameters such as initial dye concentration, amount of adsorbent (Biochar) and time of adsorption on removal of dyes were investigated. For this, liquid phase adsorption experiments were conducted in batch adsorption mode. The adsorption isotherm was developed for the effect of initial concentration of dyes. It was observed that rate of adsorption of dyes on biochar increases with increase in initial concentration of dyes.
