Organic Framework

The pillared-layer Zn-triazolate metal-organic framework (CIM-81) was synthesized, characterized, and used for the first time as a sorbent in a dispersive micro-solid phase extraction method. The method involves the determination of a variety of personal care products in wastewaters, including four preservatives, four UV-filters, and one disinfectant, in combination with ultra-high performance liquid chromatography and UV detection. The CIM-81 MOF, constructed with an interesting mixed-ligand synthetic strategy, demonstrated a better extraction performance than other widely used MOFs in D-µSPE such as UiO-66, HKUST-1, and MIL-53(Al). The optimization of the method included a screening design followed by a Doehlert design. Optimum conditions required 10 mg of CIM-81 MOF in 10 mL of the aqueous sample at a pH of 5, 1 min of agitation by vortex and 3 min of centrifugation in the extraction step; and 1.2 mL of methanol and 4 min of vortex in the desorption step, followed by filtration, evaporation and reconstitution with 100 µL of the initial chromatographic mobile phase. The entire D-µSPE-UHPLC-UV method presented limits of detection down to 0.5 ng·mL−1; intra-day and inter-day precision values for the lowest concentration level (15 ng·mL−1)-as a relative standard deviation (in %)-lower than 8.7 and 13%, respectively; average relative recovery values of 115%; and enrichment factors ranging from ~3.6 to ~34. The reuse of the CIM-81 material was assessed not only in terms of maintaining the analytical performance but also in terms of its crystalline stability.

Pharmaceuticals and personal care products (PPCPs) are abundantly used by people, and some of them are excreted unaltered or as metabolites through urine, with the sewage being the most important source to their release to the environment. These compounds are in almost all types of water (wastewater, surface water, groundwater, etc.) at concentrations ranging from ng/L to µg/L. The isolation and concentration of the PPCPs from water achieves the appropriate sensitivity. This step is mostly based on solid-phase extraction (SPE) but also includes other approaches (dispersive liquid-liquid microextraction (DLLME), buckypaper, SPE using multicartridges, etc.). In this review article, we aim to discuss the procedures employed to extract PPCPs from any type of water sample prior to their determination via an instrumental analytical technique. Furthermore, we put forward not only the merits of the different methods available but also a number of inconsistencies, divergences, weaknesses and disadvantages of the procedures found in literature, as well as the systems proposed to overcome them and to improve the methodology. Environmental applications of the developed techniques are also discussed. The pressing need for new analytical innovations, emerging trends and future prospects was also considered.

The present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples. The resultant sorbent material was physicochemically and morphologically characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and N2 adsorption analysis. OPPs pesticides extraction efficiency of two sorbents were evaluated through magnetic solid phase extraction (MSPE) using high performance liquid chromatography with ultraviolet detector (HPLC/UV). The main parameters affecting the sorbent efficiency namely extraction time and desorption solvent were optimized. Comparatively, Fe3O4 -SBA-15 achieved excellent percent recovery (97.5%) compared to the Fe3O4 -MCM-41 (87.1%) under optimum condition respectively. The result appealed that the Fe3O4 -SBA-15 composite was efficient sorbent with good capability for the preconcentration of selected OPPs from water samples.AThe present study describes the synthesis, characterization and application of two mesoporous silica material based coated magnetic nanoparticles namely Fe3O4 -SBA-15 and Fe3O4 -MCM-41 for the simultaneous preconcentration of three selected organophosphorus pesticides (OPPs) namely chlorpyrifos, diazinon and parathion methyl from water samples.
