Abstract
Biochar is the carbon-rich product from biomass under limited supply of oxygen. Biochar has been well recognized in enhancing terrestrial carbon sequestration and greenhouse gas mitigation as well as in improving soil fertility and plant productivity. To explore the differences of biochars produced from different raw materials, six biochar samples made from alfalfa straw, wheat straw, cotton straw, grape vines, sludge and lignite were selected as test material. Qualitative and quantitative analysis by fourier transform infrared spectroscopy(FTIR) and Boehm titration were used to determine the amount of the surface functional groups of biochars. Meanwhile the sca...
