A chemiluminescence (CL) method using flow injection (FI) was developed for the determination of uric acid based on the enhancement chemiluminescence intensity of luminol-hexacyanoferrate(III)-hexacyanoferrate(II) in the presence of cetyltrimethylammonium bromide and the uric acid species. The linear range was 7.0 x 10(-10) - 9.0 x 10(-7) M with a detection limit (3sigma) of 2.58 x 10(-10) M, w...

A new transducer based on a screen-printed carbon electrode has been developed for the quantification of thiram. Detection this fungicide is performance two enzymes: (1) aldehyde dehydrogenase catalyzes oxidation using NAD+ as cofactor and simultaneously, (2) diaphorase reoxidizes NADH formed in first enzymatic process due to presence hexacyanoferrate(III) which reduced hexacyanoferrate(II). Ta...

To address the challenges in remediating cesium contaminated aqueous environments, a low-cost, magnetically recoverable and superior composite adsorbent was fabricated based on concept of magnetizing montmorillonite entrapping potassium copper hexacyanoferrate that offers excellent selectivity for Cs+. The facile, green scalable synthesis route involved exchanging interlayer ions with ferrous b...
