Application

Potassium ethyl xanthogenate (ethyl potassium xanthogenate) has been used:
  • in synthesis of unsymmetrical sulfides via cross-coupling reaction, using recyclable CuO nanoparticles under ligand-free conditions
  • as surfactant to investigate the adsorption of colloidal dye Disperse Blue 3 onto pretreated polyester fabric
  • in determination of microgram amounts of cadmium in water samples by substoichiometric radiochemical method

Cadmium forms neutral, lipophilic Cd(L)2(0) complexes with diethyldithiocarbamate (DDC) and with ethylxanthate (XANT). Uptake of these complexes bythree unicellularfreshwater green algae (Chlamydomonas reinhardtii, Chlorella fusca, and Pseudokirchneriella subcapitata) was determined at two pH values (7.0 and 5.5) and compared to
