2-Mercaptoimidazole covalently bonded to a silica gel surface for the selective separation of mercury(II) from an aqueous solution
(Marcel Dekker Inc, 1997-01-01)
Silica gel with a specific surface area of 365 m(2).g(-1) and an average pore diameter of 60 Angstrom was chemically modified with 2-mercaptoimidazole. The degree of functionalization of the covalently attached molecule, ...

Correlation between i.r. spectra and thermal decomposition of cobalt(II), nickel(II), copper(II) and mercury(II) complexes with piperidinedithiocarbamate and pyrrolidinedithiocarbamate
(Kluwer Academic Publ, 2000-12-01)
The thermal decomposition of pyrrolidinedithiocarbamate and piperidinedithiocarbamate complexes of CoII, NiII, CuII and HgII have been studied by thermogravimetry and differential scanning calorimetry. The decomposition ...
Spectroscopy and thermal studies of valsartan compounds with metals Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) in the solid state
(2021-04-01)
Solid-state M-Val compounds were synthesized, where M stands for bivalent metals (Mn, Fe, Co, Ni, Cu, and Zn), and Val stands for valsartanate ion (C24H27N5O32−). The thermal and spectroscopic study of the compounds was ...
