a form of solvent extraction with p

a form of solvent extraction with phase ratio values higher than
500 [23–25]. It is also inexpensive, sensitive and effective for the
removal of interfering matrices. Compared with conventional solvent
extraction it has the advantage of great enhancement of the
concentration in the organic phase, and reduction in the amount of
organic solvent. This technique was first used for the extraction and
determination of polycyclic aromatic hydrocarbons (PAH) [23], we
extend its application for extraction of metal ions followed by its
determination by graphite furnace atomic absorption spectrometry
[24,25].
In this study, the possibility of extraction of an ion-pair in 1-
undecanol and implementation of SFODME in combination with
FAAS for trace element analysis was considered. Cadmium, in aqueous
samples was converted to CdI4
2− and was extracted with
methyltrioctylammonium chloride in 1-undecanol and was determined
by flow injection flame atomic absorption spectrometry
(FI-FAAS).

Oplosmiddel ekstraksie fase met 'n vorm van verhouding waardes Hoër as
500 [23-25]. Dit is ook Goedkoop, doeltreffende en sensitiewe vir die
opheffing van die inmenging matrikse. In vergelyking met konvensionele Solvent
onttrekking het die voordeel van Groot verbetering van die
konsentrasie in die organiese fase, en die vermindering in die bedrag van
organiese oplosmiddel. Eerste tegniek is gebruik vir hierdie onttrekking en die
bepaling van PAK aromatiese koolwaterstowwe (PAK) [23] Ons
Brei Aansoek vir sy SY onttrekking van metaalione gevolg deur
Graphite Furnace atoomabsorpsiespektrometrie bepaling deur
[24,25].
In hierdie studie ,. die moontlikheid van onttrekking van 'n ioon-pair in 1-
Undecanol en implementering van SFODME in kombinasie met
Faas vir Trace Ontleding element beskou. Kadmium, in waterige
monsters is omgeskakel na CdI4
is 'n uittreksel met 2-en
-1 in Methyltrioctylammonium chloried Undecanol en was vasbeslote
vlam atoomabsorpsiespektrometrie vloei inspuiting
(FI-Faas).
