Evaluation of Titanate Nanotubes (TiNTs) as a Modifier for the Determination of Lead (II) by Differential Pulse Adsorptive Stripping Voltammetry (DPAdSV)

AbstractThe renewable mercury film electrode, applied for the determination of papaverine traces using differential pulse adsorptive stripping voltammetry (DP AdSV) is presented. The calibration graph obtained for papaverine is linear from 1.25 nM (0.42 µg L−1) to 95 nM (32.2 µg L−1) for a preconcentration time of 60 s, with correlation coefficient of 0.998. For the renewable mercury electrode (Hg(Ag)FE) with a surface area of 9.1 mm2 the detection limit for a preconcentration time of 60 s is 0.7 nM (0.24 µg L−1). The repeatability of the method at a concentration level of the analyte as low as 17 µg L−1, expressed as RSD is 3.3% (n=5). The proposed method was successfully applied and validated by studying the recovery of papaverine from drugs, urine and synthetic solution.

[Determination of Cr(VI) Metal Using Differential Pulse Adsorptive Stripping Voltametry Method with Calconcarboxylic Acid as Complexing] Penelitian ini menggunakan metode differential pulse adsorptive stripping voltammetry (DPAdSV) dengan elektroda merkuri tetesan gantung (HMDE) untuk menentukan logam Cr(VI) dengan Calconcarboxylic Acid (CCA) sebagai ligand dalam sampel air laut. Metode ini terjadi berdasarkan deposisi Logam-CCA pada elektroda merkuri pada periode waktu tertentu. Dengan menggunakan scan potensial kearah negatif dan voltammogram differential pulse akan menghasilkan voltammogram yang berbeda. Parameter instrumental dan kimia yang dapat meningkatan pegukuran diperoleh kondisi optimalnya antara lain, konsentrasi CCA 0,5 mM, pH 6, potensial deposisi (Edep) -0,3 V, waktu deposisi (tdep) 60 detik, konsentrasi buffer asetat 0,4 M, scan rate 150 mV/s, tinggi pulse 90 mV, ukuran tetesan merkuri 4 mm2, Linieriti logam Cr (Ip vs konsentrasi) pada kisaran 5 sampai 200 µg/L. Batas deteksi Cr(VI) adalah 0,23 µg/L, standar deviasi relatif 0,24%, recovery 98%. Metode DPAdSV dengan CCA ligands untuk penentuan logam Cr(VI) sukses diaplikasikan pada sampel alam yaitu air laut dan air sungai.
