Biosorption (removing) of Cd(II), Cu(II) and methylene blue using biochar produced by different pyrolysis conditions of beech and spruce sawdust
Original language description
The influence of pyrolysis parameters (temperature, heating rate) onadsorption properties of wood charcoals was studied. Beech and spruce wastesawdust were investigated by TG-MS technique, and it was revealed that pyrolysisof sawdust consists at least of two overlapping reactions characterized by differentvalues of activation energy Ea(151 and 184 kJ/mol for beech sawdust, 157 and172 kJ/mol for spruce sawdust). Based on obtained results, adsorbents from studiedsawdust were prepared through pyrolysis at 400-700 C with heating rate 10 or 2 K/min and their surface and adsorption characteristics were investigated. It was foundthat higher pyrolysis temperature (700 C) and higher heating rate (10 K/min)generally improved micropore surface areas of beech and spruce biochars. Theadsorption capacity of spruce biochar for Cu(II) and Cd(II) increased with higherpyrolysis temperature and lower heating rate (2 K/min) up to 0.14 and 0.12 mmol/g,respectively. In the case of beech biochar, the adsorption capacity for heavy metalions has no distinct dependence on pyrolysis temperature nor heating rate. Theopposite effect of heating rate was found in the case of the methylene blue uptake,better adsorbent can be prepared by pyrolysis with heating rate 10 K/min. The effectof pyrolysis temperature is not clear in this case.
