文摘
- •
Two novel types of thoria nanoparticles-carbon paste electrodes were prepared.
- •
Using these working electrodes, inorganic arsenic speciation was possible.
- •
The most common interferences were avoided under the best instrumental conditions.
- •
An interference-free DPASV procedure was developed for determination of arsenic.
