Drying temperature can change the specific surface area of Phanerochaete chrysosporium pellets for copper adsorption

Abstract

Wet Phanerochaete chrysosporium dried at 40°C yields about 3 times higher specific surface area (0.89 m2/g) than when dried at 80°C (0.34 m2/g) or 100°C (0.32 m2/g). An increased rate of evaporation and thermal expansion of water at the higher temperatures is probably responsible. The pellets dried at 40°C have approx. twice the Cu2 adsorption capacity (10.5 mg Cu2/g) than the pellets dried at 80°C (6.1 mg Cu2/g) or 100°C (5.8 mg Cu2/g). © Rapid Science Ltd. 1998
