The use of Phanerochaete chrysosporium for modification of bentonite for preconcentration and determination of heavy metals

Abstract

In this study, a solid phase extraction method was successfully applied in the preconcentration and determination of trace levels of Cu(II) and Cd(II) ions and Phanerochaete chrysosporium (white rot fungus) modified bentonite was used as adsorbent. After the biosorption of Cu(II) and Cd(II) ions, metal concentrations in the samples were determined by atomic absorption spectrophotometry. pH, adsorbent amount, eluent type, sample volume, and flow rate, which are effective in the adsorption of metal ions, have been studied. 1 M HCl was used for desorption of these metal ions retained (recovery 95–100%). In addition, the effect of interfered ions has also been investigated. Sorption data were examined according to Langmuir and Freundlich adsorption equations. The results obtained show that the applied method has a high metal biosorption capacity, and Cu(II) and Cd(II) ions are successfully recovered. It was also successful in applying the proposed enrichment method to real water samples.Recovery values between 92.3% and 97.3% were obtained for the studied metal ions. According to the results, the proposed method can be successfully applied to water analysis at 95% confidence interval.

“…In addition, other techniques can be used to enhance the bentonite adsorption capacity. Kocaoba et al combined microorganisms with bentonite and studied the application of solid-phase extraction methods using modified bentonite with Phanerochaete chrysosporium as an adsorbent for the preconcentration and determination of Cu 2+ and Cd 2+ ions . Sheng prepared aluminum-based supported bentonite using a microwave method, exploiting its large interlayer spacing, specific surface area, and high surface activity to enhance its adsorption performance…”

“…However, many previous studies have investigated the mineralogical and radiometric characterization of sepiolite minerals and the removal of radioactive elements or HMs from various environmental samples using sepiolites. [18][19][20][21][22][23][24][25][26][27][28]. This reseach particularly to aim the levels of 14 HMs in 30 sepiolite samples collected from 3 quarries located center area of Turkey by using (EDXRF) spectroscopy.…”
