【摘要】The biosorption of Direct Black 38 by dried anaerobic granular sludge in a batch system under specific temperatures and initial pH was investigated.The adsorption reaction is pH dependent with higher removal at low pH.The adsorption equilibrium data fit very well with both Langmuir and Freundlich models in the concentration range of Direct Black 38 at all chosen temperatures.The adsorption parameters show that the adsorption of Direct Black 38 is an endothermic and more effective process at high temperatures.The kinetics of adsorption was found to be second order and adsorption rate constants increased with increasing temperature.Activation energy was determined as 26.8 kJ/mol for the process.This suggests that the adsorption of Direct Black 38 by dried anaerobic granular sludge is chemically controlled. 【总页数】5页(198-202)
