| dc.description.abstract | Using the voltammetric senor which is constracted in our laboratory and the membrane stabilized interface between two immiscible electrolyte solution in a flow injection system the transfer of anions (CIO ,NO & 01 land catiol's 4 '3 + + (i( Na lfrom the aqueous to the organic phase have been investiJ'(ated.ln order to determine the Horking potential region of the system the behaviour of the potential-current dependence of the support inA electrolytes Here studied. The iR drop resulting fron the dilution effect of tl,e distilled Ivate'!, at the interface has been investigated and it Has compensated by increasing 1;he concentration of the supporting electrolyte in t,he aqueous phase . Dependence of the peak current on the applied concentration of various ions (ClO , 4 been investigat,ed. The det,ermination potentials _. + + NO , K & Na 3 of K+ and Na+ in the presence of dibenzo-18-croHn-6 in the and on have Has made organic + phase. The method "as applyed to t),e determination of Na and + K in blood serum samples Hnd the values obtained \Vere in good agreement Iii th the values obtained by flame photometric method. The selectivity of the method Has also studied and lias found to be potential dependent and governed bv the partial sensitivity of the individual ion. A method has also been proposed for the deternd ngtion of a particu} ar ion in the presence of another ion. The detection limit of the detector has heen determined to be about 0.25 µM for perchlorate ion. Thus the method is rapid, precise, sensitive for the determination of some anions and cations. | en_US |
