“…Based on the following two assumptions, (1) aluminum species in the tea were all sorbed on the IRA-CAS resin, and (2) the extraction efficiency was both the same (48.57%), the aluminum content was estimated to be 1.46 and 1.10 ppm for first and second infusion, respectively. Although the estimated values fell in the range of 0.8-4.9 ppm [31][32][33][34][35], the variation could be attributed to the sample preparation, such as the source of leaf and the infusion methods, and the consideration of limited sorption of aluminum species existing at pH <1 solution.…”

A conducting polymer was electrochemically prepared on a Pt electrode with newly synthesized 3'-(4-formyl-3-hydroxy-1-phenyl)-5,2' : 5',2''-terthiophene (FHPT) in a 0.1 M TBAP/CH 2 Cl 2 solution. The polymer-modified electrode exhibited a response to proton and metal ions, especially Al(III) ions. The poly [FHPT] was characterized with cyclic voltammetry, EQCM, and applied to the analysis of trace levels of Al(III) ions. Experimental parameters affecting the response of the poly [FHPT] were investigated and optimized. Other metal ions in low concentration did not interfere with the analysis of Al(III) ions in a buffer solution at pH 7.4. The response was linear over the concentration range of 5.0 Â 10 À8 -7.0 Â 10 À10 M, and the detection limit was 5.0 Â 10 À10 M using the linear sweep voltammetry (LSV). Employing the differential pulse voltammetry (DPV), the response was linear over the 1.0 Â 10 À9 -5.0 Â 10 À11 M range and the detection limit was 3.0 Â 10 À11 M. The relative standard deviation at 5.0 Â 10 À11 M was 7.2% (n ¼ 5) in DPV. This analytical method was successfully verified for the analysis of trace amounts of Al(III) ions in a human urine sample.
