Poly o-toluidine zirconium(IV) iodosulfosalicylate (PTZIS) is a hybrid inorganic–organic composite cation exchanger, which was synthesized by mixing an organic compound, poly o-toluidine, into the matrices of zirconium(IV) iodosulfosalicylate. On the basis of distribution coefficient, K d, the material was found to have high affinity for adsorption of Cr(III) ion. Due to its Cr(III) selective nature, ion exchanger was used as an electroactive material for preparation of an ion-selective membrane electrode. The physical properties of membrane were determined by XRD, SEM, and AFM analysis, which indicates that PVC-based Cr(III) ion-selective membrane is amorphous and porous in nature. The electrode responds to Cr(III) in a linear range from 3.16 × 10–6 to 1 × 10–1 M with a Nernstian slope of 22 ± 0.5 mV per decade change in concentration and a detection limit of 1.584 × 10–6 M. The life span of the electrode is found to be 12 weeks. The proposed electrode shows satisfactory performance over a pH range of 3.0–7.0, with a fast response time of 10s. The sensor has been applied to determination of Cr(III) ions in water samples of different origins. The sensor has been used as an indicator electrode in potentiometric titrations of Cr(III) ion with EDTA.

“…Compared with other methods, X-ray fluorescence (XRF) spectra has some potential advantages for analysis of heavy metal elements, such as multi-component analysis in site, quick detection, non-destructive and high precision, etc [5]. Actually, XRF technology has been developed rapidly and been widely applied to detect heavy metal elements in variety of environmental samples [6][7][8][9].…”

In this paper, the measurement conditions of heavy metal enriched on the filter membrane using X-ray fluorescence were talked about. According to the heavy metal enriched on the film, the specific parameters were analysed. Through many experiments, the suitable parameters were decided. In order to excite mainly heavy metal in air, the excitation voltage should be not less than 30kV. The excitation current should be between 20μA and 60μA. The measured distance should be between 4mm and 15mm. The best choice of pulse shaping time is around 6.4μs. These parameters setting should have very good application value in air heavy metal measurement.
