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

Brown trouts, Salmo trutta, were exposed to water containing 0.1 or 10 micrograms/l of 63Ni2+, alone or with potassium ethylxanthate or sodium diethyldithiocarbamate. After one and three weeks the accumulation and disposition of the 63Ni2+ in the fish were examined

Although, the xanthate process has been shown to be an effective method for heavy metal removal from contaminated water, a heavy metal contaminated residual sludge is produced by the treatment process and the metal-xanthate sludge must be handled in accordance
