Iron was estimated colorimetrically , the results were found to be reproducible and the method was economical and less time consuming. The method was successfully applied to cement sample and results were found to be accurate and precise as the more sophisticated colorimeter was commonly used for ...
Benefiting from the enlarged electrode effective surface area, enhanced electron transfer and the synergic impact between Ag NPs and FeS2, the limit of detection for Ag/FeS2 hybrids was identified to be 0.6 μM in electrochemical assay and 3.0 μM in colorimetric detection. Furthermore, the ...

ferrous ironironglasscolorimetric methodTechnical Committee 2 of the International Commission on Glass has been requested to establish a reliable method for analysing iron valence states in glass. The optimised procedure is based on cold decomposition of glass sampl...
The measurement of low levels of ferrous and total reactive iron (TRFe) using three common colorimetric methods (bathophenanthroline (BPA), triazine (TPTZ), and ferrozine) in freshwater was evaluated. The BPA method, due to a hexanol extraction step, had unacceptably high limits of detection with...
