BJOC · Reacting 1,3,5benzenetricarbonyl chloride and 1,4phenylenediamine in a ball mill afforded 75% of the desired 2D polymer 24 within 15 min . When using 4,4'diaminobiphenyl in place of 1,4phenylenediamine the analogous 2D structure comprising biphenylene units was obtained within the same time albeit with a lower yield (≈65%).
New insights into the sorption mechanism of cadmium on red .Effectiveness and mechanism of cadmium (Cd) sorption on original, acidified and ball milling nanoparticle red muds were investigated using batch sorption experiments, sequential extraction analysis and Xray absorption near edge structure (XANES) spectroscopy. The maximum sorption capacity of Cd was,, and mol/kg for the original, acidified, and nano .
