摘      要：The biosorption of Direct Black 38 by dried anaerobic granular sludge in a batch system under specific temperatures and initial pH was *** adsorption reaction is pH dependent with higher removal at low *** adsorption equilibrium data fit very well with both Langmuir and Freundlich models in the concentration range of Direct Black 38 at all chosen *** adsorption parameters show that the adsorption of Direct Black 38 is an endothermic and more effective process at high *** kinetics of adsorption was found to be second order and adsorption rate constants increased with increasing *** energy was determined as 26.8 kJ/mol for the *** suggests that the adsorption of Direct Black 38 by dried anaerobic granular sludge is chemically controlled.
