Sugarcane bagasse wastes as activated charcoal nanopore powder and tablets for adsorption of heavy metal Pb (II) waste

Abstract

Sugarcane Bagasses are sugar industry wastes can be made activated charcoal in the size of nanopores such forms as powder and tablets to be used as waste absorbents of heavy metal Pb(II). The procedure preparation of sugarcane Bagasses using a drier and a crusher to form powder, carbonization at 300 °C, activation using HCL 5 N, 200 mesh sieving, and sonification to obtain sugarcane Bagasse nanopore powder, the powder can be processed to be tablets. The absorbance testing on heavy metal Pb(II) was carried out using an artificial sample of Pb(NO3)2 solution as well as absorbents in the forms of powder and tablets. Various contact times of sugarcane Bagasse nanopore powder has given results the best contact time occurs in time duration of 3 hours leading to a decrease in concentration of sample Pb(II) by 69.97 %. Various contact times of sugarcane Bagasse nanopore tablets were obtained by adding 1.5 gram of a tablet into 20 ml of the sample solution, the best contact time occurs in time duration of 3 hours leading to a decrease in 35.86 %. Various stirring speeds, in which 25 ml of the sample was added 0.1 gram of nanopore powder and then shaker, the optimum results on 105 rpm can decrease 78.51%. Various stirring times with static stirring speed of 105 rpm the optimum results 60 minutes leading to a decrease in concentration of the sample by 78.06%.
