Speciation of inorganic selenium by solid phase extraction using nanozirconium oxide/boron oxide composite material

Không đóng trình duyệt đến khi xuất hiện nút TẢI XUỐNG

The speciation and preconcentration of selenium were carried out by solid phase extraction using nanozirconium oxide/boron oxide (ZrO2/B2O3). Electrothermal atomic absorption spectrometry (ETAAS) was used for detection. This preconcentration and/or speciation method depends on the retention of Se(IV) ions selectively as its ammonium pyrrolidine dithiocarbamate (APDC) complex on the sorbent. The effects of pH, flow rate, and volume of sample solution and eluent type were investigated for determining the optimum preconcentration and speciation conditions. |
