zinc thiocyanate is the inorganic compound with the formula Zn(CH)(NO)(O)(CH). It is a white, hygroscopic powder or crystal and is soluble in water and alcohol. zinc thiocyanate is used as a dyeing agent and an analytical reagent. It is also used as a swelling agent for cellulose esters and in rubber chemistry.
The ambidentate nature of the thiocyanate ion is well known, and it has been observed that zinc prefers to be N bonded to it, mercury to be S bonded, and cadmium is able to bridge it. Raman spectroscopy has been used to examine aqueous complexes with varying ratios of thiocyanate to zinc, and the resulting spectra show no evidence of either change in bonding preference or bridging.
The sorption of a zinc phthalocyanine-zinc porphyrin dyad assembled by two imidazole-C units onto polyurethane foam (PUF) has been investigated under various conditions. The adsorption follows Langmuir and Dubinin–Radushkevich (D-R) isotherms over the entire concentration range studied, and the equilibration time was found to be dependent on the ions present in the solution. The presence of sulphate, ascorbate and bromide enhances the sorption to some extent whereas nitrate, Pb(II) and Cu(II) decreases it significantly.
