Speciation of inorganic arsenic by μ-thin-layer chromatography coupled with laser ablation inductively coupled plasma mass spectrometry based on an ion imprinted polymer.

An efficient strategy utilizing μ-thin layer chromatography coupled with laser ablation inductively coupled plasma mass spectrometry (μ-TLC-LA-ICP-MS) based on an IIP (ion imprinted polymer) was developed for the speciation of inorganic arsenic [As(III) and As(V)]. The characterization of the fabricated IIP was performed applying Fourier-transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). To prepare the thin layer chromatography plate, CaSO (as a binder) was incorporated with the IIP.
