Original research PREPARATION AND CHARACTERIZATION OF BAMBOO PEEL BIOCHAR BY USING SLOW PYROLYSIS FOR THE REMOVAL OF CD AND PB IN SOIL (BRASSICA CAMPESTRIS)Pages 115-122
Abstract
The experiment was conducted at the University of Haripur, nursery. There are two groups in the research heavy metals and biochar. Cadmium(Cd) and Lead (Pb) spiked with soil different concentrations of 0.5 ppm and 300 ppm in plastic pots after fifteen-day amendment with various application rates of biochar (2.5 mg/kg, 3.5 mg/kg, 5 mg/kg). Brassica campestris are harvested after 45 days for two days air dry and heated in an oven to remove the moisture for powdered form is obtained and weighs 0.5-gram roots and shoots separately and the sample is ready for digestion. The 5mg/kg application rate of biochar has enhanced nitrogen (N), potassium (K), and phosphorus (P). The bioaccumulation factor is higher than the bioaccumulation coefficient because biochar adsorbed the cadmium and lead on their surface and transfer to the shoot was reduced. Cadmium and Lead reduced the Brassica campestris roots and shoots and damaged the overall structure of the plant. The pH and EC play an important role in overall research of biochar-enhanced physical parameters compared to those without bamboo peel biochar. Brassica campestris is grown in the winter season in the presence of sunlight and a lot of water is needed it also can absorb in root and shoot parts of plants. The biochar is higher than cadmium and lead because it is rich in micro-nutrients and growth parameters. The FTIR result showed that the bamboo peel biochar decreased by 45% as compared to raw bamboo peel because it has a large surface area to immobilize Cd and Pb in the soils.
Keywords: Cadmium (Cd), Lead (Pb), Bioaccumulation factor (BAF), Bioaccumulation coefficient (BAC).
