In this study, a new and efficient analytical method was developed to determine hexavalent chromium, Cr (VI), in water by flame atomic absorption spectrometry (FAAS). This method consists on the simultaneous selective extraction and preconcentration of Cr (VI) in water by dispersive solid phase extraction (DSPE), using Zn-Al layered double hydroxide intercalated with L-Alanine (ZnAl-ALA-LDH) as adsorbent. Experimental parameters that influence Cr (IV) determination efficiency, such as pH, time and interfering ions were studied and optimized. After selective extraction of Cr (VI) in the presence of Cr (III) at pH 5.2, ZnAl-ALA-LDH was dissolved in H2SO4 5 mol.L-1. An interesting property of this material is its immediate dissolution at pH values below 3. The complete ZnAl-ALA-LDH dissolution after adsorption ensured that all Cr (VI) adsorbed was analyzed by FAAS, dispensing the use of eluents during the process and thus decreasing the extraction time. In addition to the selective extraction of Cr (VI), the method also allowed sensitivity increase and interference reduction by pre-concentration. Calibration was linear in the range of 20 to 700 mu g.L-1 (r(2) > 0.99). The limits of detection (LOD) and quantification (LOQ) were 7.1 mu g.L-1 and 23.6 mu g.L-1, respectively. Relative standard deviation (RSD) was 2.7% (n = 10). The method accuracy was verified by analyzing a certified water containing Cr (VI) (Cr (VI)-QC1453) and recovery studies on drinking water samples.

Summary: This review focuses on versatile biomaterials based on nanocomposites for drug delivery and tissue engineering. Layered hydroxides can intercalate bioactive species and hold metal cations, providing elevated loading capacity and modified release profiles. They also exhibit beneficial characteristics in tissue integration and collagen formation. The association between biocompatible polymers and layered hydroxides produces multifunctional nanocomposites with stimuli-responsiveness and appropriate mechanical properties, enabling fine-tuning of drug release. Studies have shown the higher performance of these composites compared to the hybrid or free drug.

Construction of SERS substrates by gold nanoparticles assembly on polymeric matrices

F. Moyra Vieira, C. M. Gabriela Calisto, Celly Izumi

Summary: This study describes a method for fabricating stable and reproducible large-area surface-enhanced Raman scattering (SERS) substrates based on the assembly of pre-synthesized gold nanoparticles on reconstructed poly(styrene-block-2-vinylpyridine) (PS-b-P2VP) films. The results show that the annealing treatment and the molecular weight of the copolymers strongly influence the dispersion of nanoparticles and the SERS enhancements. Water and ethanol swelling of the micelles allow for high uniformity of nanoparticle deposition, while more efficient SERS enhancement is observed in the nanocomposites treated with toluene/THF vapor annealing and thermal annealing.

Krzysztof Greda, Maja Welna, Anna Szymczycha-Madeja, Pawel Pohl

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.
