摘要

The ligand (ionophores H) based on 2-amino-1,4-naphthoquinone have been synthesized and exploredas neutral ionophores for preparing polyvinyl chloride-based membrane sensor for the determination ofyttrium(III). During the optimization, the addition of potassium tetrakis(4-chlorophenyl) borate andvarious plasticizers, viz., o-NPOE, DBP, DBBP, DOP and CN have improved performance of thesensors. The best performance was obtained with the sensor number 8, with composition (%,w/w)ionophore H (3.5%): PVC (30.0%): o-NPOE (63.0%): KTpClPB (3.5%). This sensor exhibits Nernstian response with slope 19.8 mV/decade of activity in the concentration range 2.310 to 1.010 M yttrium (III), performs satisfactorily over wide slight acidic pH range of (2.5.5) with afast response time (12 s). The sensor was also found to work satisfactorily in partially non-aqueousmedia up to 20% (v/v) content of acetonitrile, ethanol and methanol. The proposed sensor can be usedover a period of 2.5 months without significant drift in potentials. The quantitative application ofsensor number 8 was also evaluated in comparative analysis of yttrium(III) with Flame-AAS.
