Electrochemical behaviour of chalcopyrite in the absence and presence of dithiophosphate
Güler, Taki; Hiçyılmaz, Cahit; Gökağaç, Gülsün; Ekmekçi, Zafir (Elsevier BV, 2005-02-07)
Electrochemical behaviour of chalcopyrite was investigated in collectorless condition and in the presence of dithiophosphate (DTP), which is a selective collector for chalcopyrite, by cyclic voltammetry (CV) study. Diffuse Reflectance Infrared Fourier Transformation (DRIFT) spectroscopy was employed to identify surface species of DTP at chalcopyrite surface. CV tests established the certain degree of irreversibility in the absence of DTP possibly due to preferential dissolution of iron ions in slightly acid...

Hiçyılmaz, C; Altun, Naci Emre; Ekmekçi, Zafir; Gökağaç Arslan, Gülsün (null; 2006-09-01)
This study investigates the electrochemical behavior of pyrite in collectorless and DTPI (sodium disobuthyldithiophosphinate) induced conditions to identify the nature of interactions between pyrite and DTPI with respect to pulp pH and pulp potential (Eh). Electrochemical investigation from acidic to alkaline (pH = 4.67- 11.0) conditions were performed using cyclic voltammetry technique in cathodic to anodic potential range (-505 to +595 mV SHE). DRIFT spectroscopy were also done after polarization at varyi...

A new monomer, 4-(thiophen-3-yl methyleneamino)benzene sulfonate) (ThSA), was synthesized and characterized. Electrochemical polymerization of ThSA yields a water-soluble and self-doped polymer (PThSA). This polymer was characterized by FT-IR, NMR, DSC, XRD and conductivity measurements.

Electrochemical copolymerization of thiophene containing pseudo-polyether cages with pyrrole
Cihaner, Atilla; Önal, Ahmet Muhtar (2006-01-01)
Conducting copolymers were synthesized via the electrochemical oxidation of pyrrole (Py) in the presence of the monomer 1,12-bis(2-thienyl)-2,5,8,11-tetraoxadodecane (1). The presence of monomer I in the electrolytic solution greatly changed the CV behavior of Py during its potensiodynamic polymerization. The electroactivity of poly(I-co-Py) increased with the increasing amount of I in the comonomer mixture. Copolymer films were prepared via constant potential electrolysis in an electrolytic solution contai...
