Zeolite-Modified Carbon Paste Electrode for Determination of Copper Using Anodic Stripping Voltammetry Method

Abstract: ABSTRAKPada penelitian ini telah dilakukan pengukuran logam Cu(II) menggunakan elektroda pasta karbon (EPK) tanpa dan termodifikasi zeolit dengan metode voltametri pelucutan anodik. Parameter yang diamati yaitu kondisi optimum (waktu deposisi dan laju pindai), komposisi modifier zeolit yang ditambahkan, dan uji validitas elektroda kerja. EPK termodifikasi zeolit pada kondisi pengukuran optimum digunakan untuk menentukan konsentrasi ion logam Cu dalam sampel air limbah pembuatan gong. Hasil penelitian menunjukk… Show more

“…6,9 To overcome these challenges, several methods involving chemical modification of carbon substrates have been developed. 23,[45][46][47][48][49] Nevertheless, performing cyclic voltammetry on unmodified graphite remains challenging. 50 Many efforts have focused on modifying carbon sensor surfaces with different materials to improve their analytical capabilities for arsenic detection and achieve detection limits below the WHO recommended level of 10 μg l −1 .…”
