TI  - [Properties of maize stalk biochar produced under different pyrolysis 
      temperatures and its sorption capability to naphthalene].
PG  - 1884-90
AB  - Biochar was made from maize stalk under three different temperatures of 300, 500 
      and 700 degreeC. The elemental composition of biochar was measured by elemental 
      analyzer. Scanning electron microscope (SEM) was used to measure the surface 
      morphology. Sorption of naphthalene to biochar was researched by batch sorption 
      experiments. Results showed that, with the increase of temperature, C content 
      increased from 66. 79% to 76. 30% , H and O contents decreased from 4.92% and 19. 
      25% to 3. 18% and 9.53%, respectively; H/C, O/C, (O + N)/C, aromaticity and 
      hydrophobicity increased, and polarity decreased. SEM results showed that maize 
      stalk biochar was platy particles, and its roughness of surface increased with 
      increasing temperature. The sorption of naphthalene on biochar followed the 
      Lagergren pseudo-second order dynamic sorption model. Initial sorption rate and 
      equilibrium sorption capacity increased as preparation temperatures increased at 
      the same initial concentration of naphthalene. The isotherm sorption behavior can 
      be described by the Freundlich model, which indicated that, as pyrolysis 
      temperature increased, the sorption capacity of biochar increased, and 
      nonlinearity increased first and then decreased. Biochar derived from maize stalk 
      had distinct features when compared with other feedstocks, and its elemental 
      composition, surface features and sorption behaviors were significantly 
      influenced by pyrolysis temperature.
