3.1 Adsorption of Ammonium Ion on BC
Since plenty of pores were formed during the
pyrolysis of bamboo at high temperature, BC has
achieved high adsorption capacity, which is one of its
important characteristics, with a large specific surface
area (as shown in Table 1, the specific surface area of the tested BC reached 330 m2 g−1 when carbonized at
600°C).
