Batch experiments were carried out to determine the capacity of Pseudomonas fluorescens biomass to adsorb Sr(II) ions from aqueous solution with respect to pH, initial Sr(II) concentration, contact time and biomass dose. The FTIR results of Pseudomonas fluorescens biomass showed that biomass has different functional groups and these functional groups are able to react with metal ion in aqueous solution...
In the present study we reported the feasibility of extracellular biopolymer(PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Ni(II) metallic ions from environmental and industrial wastewater. The ability of PF-9 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration...
The modified nanometer-sized TiO2 as a solid sorbent was prepared by using impregnation method, and characterized by using SEM. The adsorption properties of the sorbent to Co(II) in static system, main factors affecting the adsorption and desorption, adsorption isotherms and influence of coexisting ions on the determination of Co(II) were investigated by FAAS, and regeneration experiments were carried...
The objective of this study is to assess the environmentally friendly Ni(II) adsorption from synthetic wastewater using extracellular biopolymer(PS-2) produced by Pseudomonas fluorescence C-2. The ability of PS-2 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration and sorbate-sorbent contact time...
The dithizone modified sodium trititanate whisker as a solid sorbent was prepared by using impregnation method. The adsorption properties of the sorbent to Cd(II) in static system, main factors of affecting adsorption and desorption, adsorption capacity and influence of coexisting ions on the determination of Cd(II) were investigated by flame atomic adsorption spectrometry (FAAS). The selection experiment...
