A new potentiometric chloride sensor based on the use of anion receptor 2-(1-H-imidazo [4,5-f][1,10]phenanthroline-2-yl)-6methoxyphenol (HIPM) in poly(vinyl chloride) (PVC) matrix is reported. Effect of various plasticizers: 2-nitrophenyloctylether (o-NPOE), di-n-butylphthalate (DBP), diethyl phthalate (DEP), dioctylpthalate (DOP), tri-n-butyl phosphates (TBP), chloronapthalene (CN) and cation excluder,...
A potentiometric aluminium sensor, based on the use N,N′-bis(salicylidene)-1,2-cyclohexanediamine (NBSC) as a neutral carrier, in poly(vinyl chloride) (PVC) matrix, is reported. Effect of various plasticizers; 2-nitrophenyloctylether (o-NPOE), tri-n-butyl phosphates (TBP), dioctylpththalate (DOP) & chloronapthalen (CN), and anion excluder, sodium tetraphenylborate (NaTPB) was studied. The best...
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...
A μ-bis(tridentate) ligand named 2-phenyl-1,3-bis[3′-aza-4′-(2′-hydroxyphenyl)-prop-4-en-1′-yl]-1,3-imidazolidine (I) has been synthesized and scrutinized to develop iron(III)-selective sensors. The addition of sodium tetraphenyl borate and various plasticizers, viz., chloronaphthalene, dioctylphthalate, o-nitrophenyl octyl ether and dibutylphthalate has been used to substantially improve the performance...
