Popis: In general, with the increase of pyrolysis temperature, the adsorption effect of the prepared biochar to Pb2+ is better.Under the same experimental conditions at 25°C, the adsorption capacity of biochar prepared by pyrolysis of sludge at 600°C was highest which was 611.8 mg/g. The adsorption kinetics of Pb2+ in solution by BC600 is better fitted to the first order kinetic equation. With the increase of pH value of solution, the adsorption capacity of lead increased from 441.3 mg/g to 650.6 mg/g.
