Multi-pumping flow system for the determination of dissolved orthophosphate and...
Pons, Carmen; Tóth, Ildikó V.; Rangel, António O.S.S.; Forteza, Rafael; Cerdà, VíctorA multi-pumping flow system (MPFS) for the spectrophotometric determination of dissolved orthophosphate and dissolved organic phosphorus in wastewater samples is proposed. The determination of orthophosphate is based on the vanadomolybdate method. In-line ultraviolet photooxidation is employed to mineralise organic phosphorus to orthophosphate prior to detection. A solenoid valve allows the deviation of the flo...
The application of multicommutated flow techniques to the determination of iron
Pons, Carmen; Forteza, Rafael; Rangel, António O.S.S.; Cerdà, VíctorNew flow techniques such as multicommutated flow-injection analysis (MCFIA), multi-syringe FIA (MSFIA) and multi-pumping flow systems (MPFSs) have been developed. The low reagent consumption achieved by these techniques should be highlighted, as they can be regarded as environmentally friendly alternatives to conventional FIA. We present several applications of these novel flow techniques to the determination o...
