| Abstract |
| Recently, bioadsorbents have emerged as an eco-friendly
effective and low cost material option. These bioadsorbents
include some fungus, agricultural wastes, algae and bacteria. |
Biosorption attacks attention at recent years as an alternative
to conventional methods for phenolic compounds
removal from water and wastewater. Fungal cell walls and
their components have major role in the biosorption. Fungal
biomass can also take up considerable quantities of
pollutants from aqueous solutions by adsorption or a related
process, even in the absence of physiological activity. |
This study, investigated the use of non-viable pretreated
cells of Aspergillus niger, Rhizopus arrhizus and activated
sludge to remove phenol from aqueous solutions in batch
reactors. Three types of died pretreated Aspergillus niger,
Rhizopus arrhizus and Activated sludge biomasses powders
were used as a biosorbent to remove phenol present
in an aqueous solution at a concentration of 50 mg/l. It
was observed that initial pH, initial biosorbent concentration
and adsorption time affected adsorption rates. |
It was observed that, sulfuric acid-pretreated died Aspergillus
niger biomass powder was the most effective in
three types of used microorganisms to remove phenol. The
maximum removal of phenol was observed at in an initial
pH of 5 for the sulfuric acid-pretreat biomass. Approximately,
85-90 % phenol was removed for the sulfuric acid
pretreated Aspergillus niger biomass and an initial concentration
of 50 mg/l of phenol within 50 minutes. |
