A biosorption system for metal ions on Penicillium italicum – loaded on Sepabeads SP 70 prior to flame atomic absorption spectrometric determinations

Column solid-phase extraction of nickel and silver in environmental samples prior to their flame atomic absorption spectrometric determinations

“…The test procedures for the column studies are based on the literature [45][46][47]. 30 mL of solution containing 10 g of each analyte ion was added to 10 mL of buffer solution from pH 2 to pH 9.…”

“…has been used for the preconcentration studies of heavy metal ions at traces levels [39][40][41][42]. In order to expand adsorption capacities of these microorganisms, microorganisms have been loaded to adsorption resins [41][42][43][44][45].…”

Penicillium chrysogenum immobilised silica: flame atomic absorption spectrometric Pb determination in industrial effluent, sludge and food samples

“…Chitosan-immobilised Rhizopus arrhizus beads (Lang et al 2013) and immobilised Pycnoporus sanguineus beads (Yus Azila et al 2008) were reported for Pb(II). Solid phase extraction of Pb(II) was carried out with Aspergillus fumigatus (Soylak et al 2006), Penicillium italicum (Mendil et al 2008) and Aspergillus niger (Baytak et al 2007) immobilised on Diaion HP-2MG resin, Sepabeads SP 70 and silica, respectively. To the best of our knowledge, solid phase extraction and preconcentration of Pb(II) using Penicillium chrysogenum have not been reported.…”

Biosorption of lead by filamentous fungal biomass-loaded TiO2 nanoparticles

“…Biological activity is possible only for living cells whereas functional groups are utilized for both living and dead cells [20,22,25]. In addition, biosorbents are used either directly or after loaded on a support material [23,[25][26][27][28][29]. Biosorption by microorganisms loaded on solid support provides a very effective preconcentration process, due to its simplicity, low cost, higher recoveries and environmental safety making the biosorbent just like a kind of ion exchange resin [25,30].…”
