 note = {The liquid-membrane ion-selective electrode based on bis(pentafluorobenzyl)tin(IV) dibromide showed higher selectivities to α-hydroxycarboxylates than to other carboxylates without any hydroxyl group and those with a β-hydroxy group. The calibration curve for citrate was linear over a range of 10-4 to 10-2 mol dm-3 with a potential slope of -60 mV/decade. The equilibrium study on the complexation between dimethyltin(IV) and a series of carboxylates indicates the formation of stable, neutral and dimeric complexes only with α-hydroxycarboxylates, [(Me2Sn)2(H-1hc)2] {(H-1hc)-2 : species formed by deprotonation of α-hydroxycarboxylates (hc-) at α-OH groups}. The corresponding species may be spontaneously formed as electroactive species in the liquid membrane containing bis(pentafluorobenzyl)tin(IV) dibromide and acquire the selectivity to α-hydroxycarboxylates., application/pdf},
