Abstract—In the present study we reported the feasibility of Numerous technologies have been developed for the removal
extracellular biopolymer(PF-9) produced by Pseudomonas of Ni(II) from industrial wastewater, such as adsorption,
fluorescence C-9 as an alternative biosorbent to remove Ni(II) chemical precipitation, ion exchange, filtration, membrane
metallic ions from environmental and industrial wastewater. separation, and reverse osmosis. Among them, biosorption is
The ability of PF-9 to remove the Ni(II) ions was investigated the process of heavy metal removal by biological materials
by using batch biosorption procedure. The effects such as pH, such as microbial biomass and metabolites [4]. The main
dosage of biosorbent, Ni(II) initial concentration and sorbate– advantages of biosorption are high selectivity and efficiency,
sorbent contact time and agitating speed on the adsorption low
