In this study, chitosan functionalised magnetic nano-particles (CMNP) was synthesised and utilised as an effective adsorbent for the removal of Pb(II) ions from aqueous solution. The experimental studies reveal that adsorbent material has finer adsorption capacity for the removal of heavy metal ions. Parameters affecting the adsorption of Pb(II) ions on CMNP, such as initial Pb(II) ion concentration,...
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...
The present study was undertaken to evaluate the feasibility of Pseudomonas alcaligenes biomass for the removal of strontium ions from aqueous solutions. Batch experiments were performed to study the adsorption of strontium on pH, Pseudomonas alcaligenes biomass adsorbent with respect to initial Sr(II) concentration, contact time and biomass dose. The experimental data were modeled by Langmuir and...
In the present study we reported the feasibility of extra cellular biopolymer( PFC02) produced by Pseudomonas alcaligenes as an alternative biosorbent to remove Co(II) metallic ions from environmental and industrial wastewater. The effects such as pH, dosage of biosorbent, Co(II) initial concentration and sorbate-sorbent contact time and agitating speed on the adsorption capacities of PFC02 were studied...
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 Pb(II) metallic ions from environmental and industrial wastewater.The ability of PF-9 to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations...
A water-soluble intermediate bi-functional compound with thioureido and carboxyl groups was prepared by reacting chitosan with ammonium thiocyanate and chloroacetic acid. The intermediate compound was then cross-linked by epichlorohydrin to prepare a novel water-insoluble cross-linked chitosan aiming to be used as an adsorbent for heavy metal wastewater treatment. Both the intermediate compound and...
