Summary: Two extremophilic biosorbents were used to successfully remove Cu(II), Ni(II), and Pb(II) from aqueous solutions. The biosorbents showed high affinity for these metal ions, with removal rates ranging from 73.6% to 100%, and the removal order was Pb(II) > Cu(II) > Ni(II). Both Langmuir and Freundlich models were suitable for describing the adsorption process, with the pseudo-second-order reaction model being more accurate than the pseudo-first-order model kinetically.

The results showed that Mn and Zn had the highest bioaccessible values among all the samples, while the values for Cu were significantly lower. Statistical analysis methods such as correlation analysis, principal component analysis (PCA), and cluster analysis (CA) were used to examine the relationships among the total, gastric, and gastro-intestinal element concentrations.

Summary: A new sulfonamide based polymeric adsorbent (5ATT-CSPS) was prepared and characterized. It was used as an adsorbent for speciation of chromium in various water samples and lettuce extracts. The recovery of Cr(III) was optimized by adjusting pH, contact times, elution conditions, sample volume, co-existing ions and adsorption capacity. The adsorbent showed good performance for adsorption of Cr(III) with high adsorption capacity and high recovery rate. The method had a low detection limit and good precision, and its accuracy was verified by certified reference material and recovery studies.
