Li, Fuzeng published the artcileFlotation and adsorption mechanism studies of antimony sulfide with 5-heptyl-1,3,4-oxadiazole-2-thione as a collector, Quality Control of 111-11-5, the main research area is antimony sulfide heptyl oxadiazole thione collector flotation adsorption.
Oxadiazole-thione compounds include the conjugated N-, O- and S-donor atoms and possess special metal-chelating properties. In the paper, an alkyl oxadiazole-thione surfactant, 5-heptyl-1,3,4-oxadiazole-2-thione (HpODT) was designed and synthesized as a chelating collector used for the recovery of antimony sulfide. Micro-flotation tests showed that the HpODT has better recovery and selectivity for antimony sulfide against iron and cadmium sulfide in comparison with sodium iso-Bu xanthate (SIBX). The adsorption anal. indicated that the adsorption of HpODT on antimony sulfide was a spontaneous-exothermic chemisorption process. The UV absorption spectrum (UVAS) revealed that HpODT might anchor on antimony sulfide surfaces by adsorption monolayers. The zeta potential and FTIR inferred recommended a chemisorption of antimony sulfide to HpODT. XPS afforded distinct proofs that the conjugated N- and S-donor atoms of HpODT coordinate with the surface antimony atoms of antimony sulfide to generate the hydrophobic HpODT-Sb surface complexes.
