Flow injection analysis films

Wangfuengkanagul and Chailapakul [9] described the electroanalysis of ( -penicillamine at a boron-doped diamond thin film (BDD) electrode using cyclic voltammetry. The BDD electrode exhibited a well-resolved and irreversible oxidation voltammogram, and provided a linear dynamic range from 0.5 to 10 mM with a detection limit of 25 pM in voltammetric measurement. In addition, penicillamine has been studied by hydrodynamic voltammetry and flow injection analysis with amperometric detection using the BDD electrode. [Pg.134]

The choice is dictated by cost and apphcabihty to the problem. The most widely used methods include spectrophotometry to measure color, ultraviolet or infrared absorption, turbidity, film thickness, and the like electrochemistry, primarily potentiometry, for the measurement of pH and cation or anion activity and gas and liquid chromatography, especially in the petrochemical industry where complex mixtures from distillation towers are monitored. Spectrophotometiic and other measurements are often rapidly made using flow injection analysis. [Pg.664]

Direct, sensitive, selective, and rapid biosensors have been developed based on OPH, organophosphoms acid hydrolase (OPAA), and parathion hydrolase (PH). Schoning and co-workers developed a silicon-based capacitive field-effect pH sensor, which can detect 2 pM of paraoxon. " The same group prepared ampero-metric and potentiometric biosensor chips by thin-film techniques and integrated them in a flow-injection analysis (ElA) system, which can detect different OP pesticides at the low pM concentration range.Recently, mesoporous carbon and carbon black-modified electrodes have been used to develop an amperometric biosensor based on OPH. With increased sensitivity, the biosensor can detect as low as 0.12 pM (36 ppb) paraoxon. ... [Pg.290]
