In this work, the direct determination of creatinine was achieved using a poly(ethyleneimine)/phosphotungstic acid multilayer modified electrode with the assistance of Copper(II) ions by cyclic voltammetry. The quantity of creatinine were determined by measuring the redox peak current of Cu(II)-creatinine complex/Cu(I)-creatinine complex. Factors affecting the response current of creatinine at the...
An integrated electrochemical hydride generation cell, mainly composed of three components (a gas liquid separator, a graphite tube cathode and a reticulate Pt wire anode), was laboratory constructed and employed for the detection of arsenic by coupling to atomic fluorescence spectrometry. This integrated cell was free of ion-exchange membrane and individual anolyte, with the virtues of low-cost,...
A new on-line sample digestion system using electromagnetic induction heating technique was developed for the determination of zinc and manganese in tea leaf by flame atomic absorption spectrometry (FAAS). The homemade electromagnetic heating column (EMHC), whose effective diameter was about 1mm, was composed of a polytetrafluoroethylene (PTFE) outer tube and seven compactly packed PTFE coil-coated...
