Fabrication of Spiny-like Spherical Copper Metal–Organic Frameworks for the Microextraction of Arsenic(III) from Water and Food Samples before ICP-MS Detection
Spiny-like spherical copper metal–organic frameworks (SSC-MOFs) were prepared and characterized via SEM, TEM, EDS, XRD, FTIR and the BET surface area. The fabricated SSC-MOFs were applied to develop a procedure for the microextraction of trace arsenic(III) for preconcentration. The results show that a copper- and imidazole-derived metal–organic framework was formed in a sphere with a spiny surface and a surface area of 120.7 m2/g. The TEM confirmed the perforated network structures of the SSC-MOFs, which were prepared at room temperature. The surface functional groups were found to contain NH and C=N groups. The XRD analysis confirmed the crystalline structure of the prepared SSC-MOFs. The application for the process of microextracting the arsenic(III) for preconcentration was achieved with superior efficiency. The optimum conditions for the recovery of the arsenic(III) were a pH of 7 and the use of a sample volume up to 40 mL. The developed SSC-MOF-derived microextraction process has an LOD of 0.554 µg·L−1 and an LOQ of 1.66 µg·L−10. The developed SSC-MOF-derived microextraction process was applied for the accurate preconcentration of arsenic(III) from real samples, including food and water, with the promised performance efficiency.
期刊介绍:
Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
