Abstract

Triphenyl Phosphate (TPhP), as a typical model of organophosphorus flame retardants (OPFRs), has been regarded as emerging environmental contaminants of health concern. In this study, a rapid and highly sensitive visible-light-response PEC sensor has been developed for the detection of Triphenyl Phosphate (TPhP) using electrospun template directed molecularly imprinted nanofibers modified BiOI nanoflake arrays (BiOINFs) as a photoactive electrode. The molecularly imprinted electrospun nanofibers (labeled as MI-ESNFs) were carefully characterized by scanning electron microscopy (SEM), UV spectra, FTIR spectra measurements and various electrochemical techniques. Under the optimized experimental conditions, the photoelectrochemical response was linearly proportional to the logarithm value of TPhP concentrations in the range of 0.01ngmL(-1) to 500ngmL(-1). Meanwhile, the sensor exhibited high selectivity and stability.

Phosphorus Bohr ModelSee more Phosphorus products. Phosphorus (atomic symbol: P, atomic number: 15) is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s2 3p3. The phosphorus atom has a radius of 110.5.pm and its Van der Waals radius is 180.pm. Phosphorus is a highly-reactive non-metallic element (sometimes considered a metalloid) with two primary allotropes, white phosphorus and red phosphorus its black flaky appearance is similar to graphitic carbon. Compound forms of phosphorus include phosphates and phosphides. Phosphorous was first recognized as an element by Hennig Brand in 1669 its name (phosphorus mirabilis, or "bearer of light") was inspired from the brilliant glow emitted by its distillation.
