Al 3+ selective sensor has been fabricated from poly(vinyl chloride) (PVC) matrix membranes containing neutral carrier morin as ionophore. Best performance was exhibited by the membrane having composition as morin:PVC:sodium tetraphenyl borate:tri-n-butylphosphate in the ratio 5:150:5:150 (w/w, mg). This membrane worked well over a wide activity range of 5.0×10 −7 to 1.0×10 −1...
N,N′,N″,N′′′-1,5,8,12-tetraazadodecane-bis(salicylaldiminato)(H 2 L) has been used as ionophore for preparing Mn 2+ selective sensor. Membranes of different composition with regard to ratio of H 2 L:PVC:NPOE:NaTPB have been prepared and investigated. The best performance was obtained with the membrane of composition 10:150:150:10 (H 2 L:PVC:NPOE:NaTPB) (w/w; mg). This...
Polyvinyl chloride (PVC) based membranes of dibenzo-24-crown-8(I) and 4-tert-butylcalix[8]arene (II) with and without plasticizers have been fabricated and explored as sensors for Ba 2+ and Sr 2+ , respectively. The membrane incorporating the ingredients in the ratio 8:50:6:36 [I:PVC:NaTPB (sodium tetraphenylborate): CN (1-chloronaphthalene)] works well over the concentration...
