Herein we introduce an effective approach for incorporating sulfamic acid (SA) into HKUST-1. The synthesized materials have been characterized using XRD, XPS, BET, FT-IR, SEM, EDX and TEM. The X-ray diffraction pattern of SA@HKUST-1 is analogous to that of parent HKUST-1 in line shape and d-spacing, proving that chemical modification could be obtained without damage to structural solidity. The XPS spectra confirmed successful sulfonation, due to the single S 2p peak being attributable to SO3H groups at 168 eV. Catalytic efficiency was studied for 7-hydroxy-4-methyl coumarin and 3,4-dihydropyrimidinone synthesis and it was found to be highly dependent on the amount of SA loaded over HKUST-1. Moreover, the adsorptive removal activity of some common organic and inorganic pollutants from water has been studied. To fully understand the adsorption process, the effects of initial dye concentration, pH of solution, adsorbent dosage, contact time and temperature on the adsorption process were successfully studied. Under the optimum conditions 10 wt% SA@HKUST-1 was able to reach the maximum adsorption capacity for Pb2+ (298 mg g−1) and Malachite green (290 mg g−1). Hopefully, this will facilitate research on improving the prospective use of MOFs for future applications.Herein we introduce an effective approach for incorporating sulfamic acid (SA) into HKUST-1. 相似文献

Background Genetic testing in head and neck paragangliomas (HNPG) can have profound implications in patient and family counseling.Methods Retrospective review was performed of patients with HNPG at a cancer care center from 1970 to present. Patient demographics, disease patterns, outcomes, and genetic mutations were analyzed.Results We identified 26 patients with available genetic testing results. Sixteen had mutations. Succinate dehydrogenase gene, sub unit D (SDHD) accounted for 75% of mutations, of which P81L accounted for 75%. The remainder had SDHB mutations. Patients with mutations were younger (average age 39.5 years versus 48.4 years), 63% (versus 40%) had multiple tumors, 94% (60%) had at least one carotid body tumor, and family history was positive in 38% (20%).Conclusion Patients suspected of heritable HNPG should undergo testing first at the SDHD and SDHB loci, and those with younger age, multiple tumors, carotid body tumors, and positive family history are more likely to have mutations. 相似文献
