In this paper, a novel mathematical model of stump-like peak was constructed for alternative computer simulation of capillary zone electrophoresis (CZE) by using Haarhoff–Van der Linde (HVL) function. Unlike a classical model of Gaussian peak, the developed model contains both Gaussian and plateau concentration distributions of analytes. Based on the model, the relevant computer software was developed...
Phenylephrine (i.e. PHE) and chlorprothixene (i.e. CPT), two effective and important antipsychotic drugs with low redox activity, were found generating an irreversible anodic peak at about +0.89V (vs. SCE) and +1.04V in 0.05M HAc–NaAc (pH 5.0) or NH 2 CH 2 COOH–HCl (pH 2.4) buffer solution at poly(4-aminobenzene sulfonic acid) modified glassy carbon electrode (i.e. poly(4-ABSA)/GC),...
A poly-ABSA/SWNTs composite-modified electrode was fabricated by electropolymerizing aminobenzene sulphonic acid (ABSA) on the surface of glassy carbon electrode (GCE) modified with single-wall carbon nanotubes (SWNTs). SWNTs provide a 3D porous and conductive network for the polymer immobilization. The nanocomposite film was characterized by scanning electron microscope (SEM) and electrochemical...
Clozapine, an effective antipsychotic drug, was found generating a pair of redox peaks at about 0.33–0.4V (versus SCE) at 16-mercaptohexadecanoic acid (i.e. MHA) self-assembled monolayer (SAM) modified gold electrode (i.e. MHA/Au) in 0.05molL −1 Tris–HCl (pH 8.1) buffer solution. Sensitive and quantitative measurement of clozapine based on anodic peak was established under optimum conditions...
A novel multi-walled carbon nanotubes/(3-mercaptopropyl)trimethoxysilane (MPS) bilayer modified gold electrode was prepared and used to study the electrochemcial behavior of fluphenazine and determine it. Fluphenazine could effectively accumulate at this electrode and produce two anodic peaks at about 0.78V and 0.93V (versus SCE). The peak at about 0.78V was much higher and sensitive, thus it could...
