Boron-doped diamond (BDD) is a promising electrochemical tool that exhibits excellent chemical sensitivity and stability. These intrinsic advantages coupled with the material's vast microfabrication flexibility make BDD an attractive sensing device. In this study, two different 3-in-1 electrode sensors were fabricated, characterized, investigated for their capability to detect isatin, anxiogenic indole possesses anticonvulsant activity. Each device was comprised of working, reference,...
Abstract Perfluoroalkyl substances (PFAS) have unique properties that limit their degradability in the environment. One of these PFAS is an acid (PFOA). Electrochemical oxidation a promising method for remediation, but energy costs are high. To consumption, this study used boron‐doped diamond (BDD) electrode stack and combined current density technique employed 50 mA/cm 2 first 0.25 hours then lowered to 1, 5, or 10 . This similar one developed previously; however, was only compounds...
Per- and polyfluoroalkyl substances (PFAS) are manmade compounds used in a variety of industrial applications, their consumption by humans can lead to many adverse health effects. Due high stability, destroying PFAS once they have contaminated water streams has become major challenge. One promising remediation method is electrochemical oxidation (EO). To perform EO, electrode materials that withstand current voltage conditions required. Boron-doped diamond (BDD) one such material, its...
The combination of conductivity, optical transparency, and wide anodic potential window has driven significant interest in indium tin oxide (ITO) as an electrode material for electrochemical measurements. More recently, ITO been applied to the detection trace metals using cathodic stripping voltammetry (CSV), specifically manganese (Mn). However, optimization fabrication a voltammetric method such CSV is yet be reported, nor have microstructural properties investigated CSV. Furthermore, does...
Per- and Polyfluoroalkyl substances (PFAS) are a group of manmade chemicals which persistent in the environment have shown to be toxic human health. They accumulated drinking water, groundwater, wastewater around globe for over six decades. Although production some chain lengths has ceased, remediation is critical. Current techniques include adsorbents such as granular activated carbon (GAC) Ion exchange (IX) columns. GAC merely used adsorb PFAS, but struggles with capturing shorter chains...
Toxic heavy metals such as lead (Pb), cadmium (Cd), and mercury (Hg) cause serious health complications ingestion of these toxins through contaminated drinking water, even at trace levels, has become a prominent issue. Chronic exposure to toxic Pb, Cd, Hg is carcinogenic while causing other problems like kidney failure, severe neurotoxicity, IQ loss. These are only magnified in children several stages bodily development can be severely hindered. Electroanalytical methods an attractive...
With one of the widest potential windows any solid electrode material, boron doped diamond (BDD) has proven excellence as an electrochemical tool. From water treatment and chemical synthesis to analysis sensing, BDD applications in a variety sample media. This combined with its’ stability, low background current, double layer capacitance make specifically useful trace detection, such determination toxic heavy metals polycyclic aromatic hydrocarbons (PAHs) water. We have developed several...
