Quantitative determination of anionic surfactants using optical sensors with microtiter plate reader
Publikováno v:
Sensors and Actuators B: Chemical. 203:181-186
In this study, it is shown that anionic surfactants can be readily determined by using polymer film-based optodes containing an appropriate chromoionophore. The optodes are prepared with poly(vinyl chloride) (PVC), polyurethane (PU), bis(2-ethylhexyl
