Herein, dithiocarbamate-modified biochar (BC-HDTC) was successfully synthesized with nitric acid (HNO3), thionyl chloride (SOCl2), branched PEI and carbon disulfide (CS2). The effective anchoring of amine dithiocarbamate groups onto the surface proven by SEM, FTIR, XPS, N2 adsorption–desorption experiment. batch experiments demonstrated BC-HDTC can selectively remove 98% Pb(II) within multi-met...

Convenient methods to prepare solvated rhenium oxochlorides are described; these compounds should serve as useful starting materials for rhenium chemistry. Treatment of perrhenic acid, HReO(4), with chlorotrimethylsilane or with thionyl chloride, followed by addition of tetrahydrofuran, forms the new oxochloride complexes ReO(3)Cl(THF)(2) and ReOCl(4)(THF), respectively. Small amounts of two di...
