摘要

Solvent extraction of pertechnetate anions from aqueous solutions of some mineral acids like (HCl, HNO(sub 3), HClO(sub 4), H(sub 2)SO(sub 4), salts (NaCl), NaNO(sub 3), NaClO(sub 4), K(sub 2)CrO(sub 4), Na(sub 2)CO(sub 3)) and NaOH, NH(sub 4)OH by different analytical reagents as tetraphenylarsonium (Ph(sub 4)As(sup +)), tetraphenylphosphonium (Ph(sub 4)P(sup +)), triphenyltin (Ph(sub 3)Sn(sup +)), trioctyltin (Oct(sub 3)Sn(sup +)) into organic solvents (chloroform, nitrobenzene, toluene, benzene) has been carried out at 22 +- 1 grad C. The dissertation contains following parts: (1) Introduction; (2) Aim of the dissertation; (3) Background; (4) Extraction characteristics of pertechnetate with tetraphenylarsonium in the presence of chloride, nitrate and perchlorate anions; (5) Extraction of pertechnetate with tetraphenylphosphonium in the presence of various acids, salts and hydroxides; (6) Extraction of pertechnetate with triphenyltin chloride and trioctyltin chloride; (7) Conductivity of tetraphenylarsonium, tetraphenylphosphonium triphenyltin and trioctyltin chloride and pertechnetate in nonaqueous solutions; (8) Conclusions. 27 refs, 2 figs, 1 tab.; Supervisor: Associate Professor Kopunec, R., Ph.D.
