Electrochemical sensor based on hydroxylated carbon nanotubes/platinum nanoparticles/rhodamine B composite for simultaneous determination of 2,4,6-trichlorophenol and 4-chlorophenol

A hydroxylated carbon nanotubes/platinum nanoparticles/rhodamine B composite film modified glassy carbon electrode (CNTs-OH/PtNPs/RhB/GCE) was developed for the simultaneous determination of 2,4,6-TCP and 4-CP without any pretreatment.123
