Novel bilirubin-based PVC calcium sensors.
Poly(vinyl chloride) membrane sensors for Ca(II) ions were constructed based on bilirubin (1,3,6,7-tetramethyl-4,5-dicarboxyethy-2,8-divinyl-[b-13]-dihydrobilenone) as a neutral carrier in the presence of various plasticizers (o-nitrophenyloctyl ether, dioctyl phethalate and dibutyl sebacate), which were used as solvent mediators to incorporate the carrier into the membranes. The role of plasti...
متن کاملNovel imidazole PVC-based sensor based on a thiopyrilium compound.
A novel imidazole membrane sensor based on 2,4,6-triphenyl thiopyrilium perchlorate (TTP) as an excellent charged carrier, poly(vinyl chloride) (PVC), the plasticizer dibutyl phthalate (DBP) and oleic acid as an additive is described. The sensor responds to imidazole over a wide concentration range from 1.0 x 10(-5) to 1.0 x 10(-1) M with a slope of +33.5 +/- 0.5 mV per decade. The detection li...
متن کاملSERUM GLUCOSE, BILIRUBIN, CALCIUM, PHOSPHORUS, PROTEIN AND ALBUMIN CONCENTRATIONS
Serum levels of glucose, bilirubin, calcium, phosphorus, protein and albumin were measured in a group of nine healthy men before, and on the first, 10th, 20th and 29th day of Rarnadan, and four weeks after Islamic fasting was terminated. There was a significant reduction in body weight, a significant increase in serum bilirubin and a slight decrease in calcium during Ramadan. Serum glucose decr...
متن کاملClomipramine Determination by Potentiometric PVC Membrane and Carbon Paste Sensors
Clomipramine hydrochloride, active component of an antidepressant drug, was determined in the pharmaceutical formulation by two kinds of potentiometric sensor; a PVC membrane sensor and a carbon paste electrode modified by MWCNTs and ionic liquid. Both sensors were corporated with clomipramine-tetraphenylborate ion-pair complex and they respond based on ion exchange mechanism. The best PVC memb...
متن کاملPVC Membrane Sensors for Potentiometric Determination of Acebutolol
The construction and general performance characteristics of two novelpotentiometric membrane sensors responsive to the acebutolol are described. Thesensors are based on the use of ion-association complexes of acebutolol (AC) withtetraphenylborate(TPB) (I) and phosphomolybdate(PM) (II) as exchange sites in a PVCmatrix. The sensors show a fast, stable and near- Nernstian for the mono charge catio...
