A nanomaterials-based DGT device constructed with commercial dialysis membrane as diffusive layer and nanoparticulate Fe3O4 aqueous suspension as binding phase is developed and validated for in situ aquatic arsenic measurement. The Fe3O4NPs binding phase is capable of quantitatively accumulated both As(III) and As(V) species. As(III) and As(V) species coexist in the vast majority of environmental...
An ionic liquid modified carbon paste electrode (IL/CPE) had been fabricated by using hydrophilic ionic liquid 1-amyl-3-methylimidazolium bromide ([AMIM]Br) as a modifier. The IL/CPE was characterized by scanning electron microscope and voltammetry. Electrochemical behavior of rutin at the IL/CPE had been investigated in pH 3.29 Britton–Robinson (B–R) buffer solution by cyclic voltammetry (CV) and...
An ionic liquid-type carbon paste electrode (IL-CPE) had been fabricated by replacing non-conductive organic binders with a conductive room temperature ionic liquid, 1-pentyl-3-methylimidazolium hexafluorophosphate (PMIMPF 6 ). The electrochemical responses of calcium dobesilate were investigated at the IL-CPE and the traditional carbon paste electrode (T-CPE) in 0.05molL −1 H ...
