Article Synopsis
- A new amino functionalized Cu(II) ion-imprinted hybrid column (Cu(II)-IIHMC) was created using a one-pot sol-gel method and ion-imprinting in a fused capillary, designed for trace Cu(II) analysis.
- The Cu(II)-IIHMC showed strong mechanical properties and effective selectivity for Cu(II), with an adsorption capacity of 3.13 mg g, a calibration curve ranging from 0.05-50 μg L, and a low detection limit of 0.008 μg L.
- The developed SPME-ICP-MS technique demonstrated high sensitivity and specificity for analyzing environmental and mineral samples, yielding recovery rates between 89.8-
Article Synopsis
- This study describes the creation of an amino-functionalized hybrid monolithic column using a one-step method that combines two compounds, which is then utilized in solid-phase microextraction (SPME) to analyze trace metals like Cu(II), Zn(II), Au(III), and Pb(II) using ICP-MS.!*
-
- The developed SPME matrix efficiently retains the target metal ions, showcasing significant adsorption capacities, and allows for their quantitative elution using a specific chemical solution, demonstrating strong detection capabilities with low limits of quantitation and detection.!*
-
- The method's validation with various certified reference materials confirms its accuracy and reliability, particularly in complex samples, making it an effective approach for determining ultra-tr
Article Synopsis
- A novel organic-inorganic hybrid monolithic column (A&C-HMC) was created using a one-pot process that enhances pore structure and active site density through binary porogens.
- The hybrid column demonstrates selective adsorption for chromium species (Cr(VI) and Cr(III)) at different pH levels and can be fully eluted with nitric acid.
- The A&C-HMC is effectively used as a solid-phase microextraction (SPME) matrix for analyzing chromium in environmental water samples, showcasing advantages like cost-effectiveness and high selectivity.
