Sobre IBD

Książka ta będzie idealna dla młodych badaczy w dziedzinie separacji, ponieważ opracowana przez nas metoda daje wyobrażenie o separacji i spektrofotometrycznym oznaczaniu niektórych jonów metali występujących w przyrodzie. W celu oddzielenia tych jonów metali w najczystszej postaci, proponowana metoda ekstrakcji rozpuszczalnikiem jest bardzo przydatna.Ważne cechy proponowanej metody: (i) Pozwala na selektywne oddzielenie i oznaczenie selenu(IV) i telluru(IV) od innych metali towarzyszących, takich jak Au(III), Sn(IV), Ge(IV), Fe(III) i Pb(II), (ii) Niskie stężenie odczynnika jest wymagane do ilościowego odzysku Se i Te. (iii) Ekstrakcja odbywa się w jednym etapie. (iv) Jest wolna od zakłóceń dużej liczby obcych jonów, które są związane z Se(IV) i Te(IV) w ich naturalnym występowaniu. Selektywność została zwiększona przez zastosowanie odpowiednich środków maskujących. (v) Prawdopodobna stechiometria wyekstrahowanych gatunków obliczona na 1:1 (metal: tiol). Żółty kompleks jest stabilny przez ponad 48 godzin. (vi) Z powodzeniem można go stosować do oznaczania selenu(IV) i telluru(IV) w analizie dwuskładnikowych, syntetycznych mieszanin i cienkich warstw.
