Mass Transport of Heavy Metals in Soil Columns Amended with Biochar Nanoparticles
Abstract: Biochar has potential as a valuable material for removing heavy metals from wastewater. The biochar obtained by pyrolysis of the Pomegranate Peel (PPBC) under an oxygen-limited atmosphere in a muffle furnace at 450°C. The biochar was also analyzed through SEM and FTIR for identification of particle size and functional groups. Therefore, the present work aims to study the effect of adding biochar to the soil columns (10 cm length and …

Extraction of Nicotine from Tobacco Leaves used for Animal Cleansing
Abstract: Nicotine is addictive. An average cigarette yields about 2 mg of absorbed nicotine, and in lesser doses of that order, the substance acts as a stimulant in mammals, while high amounts (50-100 mg) can be harmful. This stimulant effect is a contributing factor to the addictive properties of tobacco smoking. Nicotine’s addictive nature includes psychoactive effects, drug-reinforced behavior, compulsive use, and relapse after abstinence, physical dependence and tolerance. Nicotine can …
