Utilization of mesquite (Prosopis juliflora) wood biochar for adsorption of nickel ions in aqueous solution
Author(s): K Angalaeeswari and SPB Kamaludeen
Abstract: In this adsorption study, removal of nickel from aqueous solutions has been inquired by mesquite (Prosopis juliflora) wood biochar as a low cost adsorbent. The rate of nickel adsorbed significantly increased with increase in initial concentration of nickel solution and adsorption rate gradually decreased as the dosage of biochar increased at the pH 6 and pH 7. The maximum adsorption rate was obtained 3.05 mg g-1 at the pH 7 with the lower adsorption dosage (0.25%) of biochar at 20 mg L-1. The percent removal decreased with increased initial concentration of nickel and the percent removal increased with increased dosage of biochar at pH 6 and 7. The maximum percent removal was obtained 91.72% at the pH 7 at 1.0% biochar. Also, it helps in reduction of waste generation. Thus, the use of low cost adsorbents may contribute to the sustainability of the surrounding environment.
