The hydrogel 2a converted into sol within 1 h in the presence of Cl−, AcO−, and H2PO4−, but no gel-sol transition occurred with addition of Br−, I−, and NO3−. The 1H NMR experiments showed that the addition of Cl−, AcO−, and H2PO4− resulted in a ...

Compared to the sluggish kinetics observed in methanol-mediated side-chain alkylation of methyl groups with sp3 C–H bonds, CO2 hydrogenation emerges as a sustainable alternative strategy, yet it remains a challenge. Here, as far as we know, it is first

An accelerated solvent extraction-ion chromatographic(ASE-IC) method was developed for the extraction and determination of NO~-_3 andNO~-_2in meat. 在所建立的色谱条件下,NO3-、NO2-的质量浓度与峰面积或峰高具有很好的线性和重复性。 2.
因为我爱国 使阴、阳离子结合成化合物的静电作用。离子键 离子键是由电子转移（失去电子者为阳离子，获得电子者为阴离子）形成的。即正离子和负离子之间由于静电引力所形成的化学键。离子既可以是单离子，如Na+、CL-；也可以由原子团形成；如SO4 2-，NO3-等。离子键的作用力强，无饱和性，无方向性...
