Determination of carbofuran and diuron in FIA system using electrochemical sensor modified with organometallic complexes and graphene oxide
(Elsevier B.V., 2014-10-01)
This paper describes the development of an electrochemical sensor coupled to flow injection analysis system for the detection of pesticides. The proposed sensor was prepared using a carbon paste electrode modified with ...
Fluorimetric determination of fluoride in a flow assembly integrated on-line to an open/closed FIA system to remove interference by solid phase extraction
(Elsevier Science, 2002-11)
A simple flow injection fluorimetric method for fluoride determination is proposed. The method is based on the enhanced fluorescence of quercitin-Zr(IV) complex when fluoride ion is present in the sample. An open/closed ...
A pH optode based on thymol blue: Application to determination of co2 using flow injection analy sis system
(2010-01-01)
An optode based on thymol blue (TB), an acid-based indicator, has been constructed and evaluated as a detector in FIA system for CO2determination. The dye was chemically immobilised on the surface of a bifurcated glass ...
