Summary: In this study, the detection sensitivity of a conventional flame atomic absorption spectrophotometer (FAAS) for manganese (Mn2+) determination was enhanced by using a preconcentration method on wastewater samples. The synthesis of flower-shaped Ni(OH)2 nanomaterials as sorbent material in the preconcentration procedure was conducted. By optimizing the extraction method, including pH, desorption solvent concentration and volume, mixing type and period, nanoflower amount, and sample volume, the detection limit of the optimized method was determined to be 2.2 μg L-1, achieving a 41-fold enhancement in detection power compared to direct FAAS measurement. Spike recovery experiments with domestic wastewater confirmed the feasibility of the proposed method, with percent recoveries ranging from 95-120%.

Summary: Triadic silica-supported polyhexamethylene guanidine@nano-hydroxyapatite (HAP) composites were prepared and used for solid phase extraction of Cr (VI) in a micro-column system, with its determination by flame atomic absorption spectrometry (FAAS). The results showed that the triadic silica-supported nano-HAP composites efficiently adsorbed Cr (VI) at pH 4.0-6.0, while almost no adsorption of Cr (III) occurred. The method exhibited good linearity, detection limit, and precision for Cr (VI) determination, and it was successfully applied to the analysis of chromium contents in cereal and water samples.

Summary: An extraction and preconcentration method based on dispersive liquid-liquid microextraction (DLLME) for Cu determination in beer by flame atomic absorption spectrometry (FAAS) was developed. The main parameters that influence the extraction efficiency were studied, and the accuracy was evaluated by comparison with other methods and recovery tests. The proposed DLLME/FAAS method showed a low limit of detection and quantification for Cu determination.
