disulfate

In addition, because MESNA is a synthetic sulfur compound, it enables separation of mucus polypeptide chains by mucolysis of the disulfate bonds [9].

Also, apart from copper, the tailings include the following chemicals: sodium cyanide, sulfuric acid, sodium sulfide, potassium ethyl/amyl xanthane, sodium ethyl/isopropyl xanthane, carbon disulfate, pine oil, and trichloroethylene (16).

Pure polyaniline was prepared by dissolving of (2.59 g) of aniline hydrochloride in (50 ml) of distilled water and mixed with (5.71 g) from ammonium peroxy disulfate that dissolved in (50 ml) of distilled water in the Container of electrochemical cell at room temperature and the doped sample was prepared in the same way but both of aniline hydrochloride and ammonium peroxy disulfate was dissolved in (1 M) of [H.sub.2]S[O.sub.4] for protonation PANI by [H.sub.2]S[O.sub.4]and dissolved in (1 M) of HCl for protonation PANI by HCl and then constant voltage was applied for a certain sample for two hours.

Geneticin disulfate salt (G418) was purchased from Sigma-Aldrich.
