The proposed array of microelectrodes consists of exactly forty-three single capillaries of an inner diameter of about 10 \u00b5m filled with metallic bismuth and packed in one casing. The proposed sensor is reusable thanks to its distinctive design. The microelectrode properties of the proposed working electrodes were confirmed by comparing the analytical signals of cadmium and lead recorded from stirred and unstirred solutions during the deposition step. The practical application of the solid bismuth microelectrode array is presented by detailing the procedure for the simultaneous determination of Pb and Cd by anodic stripping voltammetry. The calibration graphs were linear from 5 \u00d7 10\u22129 to 2 \u00d7 10\u22127 mol L\u22121 and 2 \u00d7 10\u22129 to 2 \u00d7 10\u22127 mol L\u22121 for Cd(II) and Pb(II), respectively (deposition time of 60 s). The detection limits for Cd(II) and Pb(II) were equal to 2.3 \u00d7 10\u22129 mol L\u22121 and 8.9 \u00d7 10\u221210 mol L\u22121, respectively. Potential interferences were investigated. The developed procedure was successfully used for the analysis of certified water reference material and environmental water samples.<\/jats:p>","DOI":"10.3390\/molecules30132743","type":"journal-article","created":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T03:39:59Z","timestamp":1750909199000},"page":"2743","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["A Novel Approach to the Design of a Solid Bismuth Microelectrode Array: Applications in the Anodic Stripping Voltammetry of Cd(II) and Pb(II)"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5663-4326","authenticated-orcid":false,"given":"Mieczyslaw","family":"Korolczuk","sequence":"first","affiliation":[{"name":"Institute of Chemical Sciences, Faculty of Chemistry, Maria Curie Sklodowska University, 20-031 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2952-1910","authenticated-orcid":false,"given":"Iwona","family":"G\u0119ca","sequence":"additional","affiliation":[{"name":"Institute of Chemical Sciences, Faculty of Chemistry, Maria Curie Sklodowska University, 20-031 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paulina","family":"Mr\u00f3zek","sequence":"additional","affiliation":[{"name":"Institute of Chemical Sciences, Faculty of Chemistry, Maria Curie Sklodowska University, 20-031 Lublin, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"126715","DOI":"10.1016\/j.foodchem.2020.126715","article-title":"Evaluation of Sample Preparation Methods for Cereal Digestion for Subsequent As, Cd, Hg and Pb Determination by AAS-Based Techniques","volume":"321","author":"Souza","year":"2020","journal-title":"Food Chem."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1016\/j.talanta.2012.05.006","article-title":"Simultaneous Determination of Arsenic, Cadmium, Copper, Chromium, Nickel, Lead and Thallium in Total Digested Sediment Samples and Available Fractions by Electrothermal Atomization Atomic Absorption Spectroscopy (ET AAS)","volume":"97","author":"Carrillo","year":"2012","journal-title":"Talanta"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"123694","DOI":"10.1016\/j.talanta.2022.123694","article-title":"Sensitive Determination of Ag, Bi, Cd, Hg, Pb, Tl, and Zn by Inductively Coupled Plasma Optical Emission Spectrometry Combined with the Microplasma-Assisted Vapor Generation","volume":"249","author":"Greda","year":"2022","journal-title":"Talanta"},{"key":"ref_4","doi-asserted-by":"crossref","first-page":"933","DOI":"10.1039\/C9JA00427K","article-title":"Development of Preconcentration Strategies for the Simultaneous Ultratrace Determination of As, Cd and Pb in Foods by ICP-OES: Knotted-Reactor vs. Dispersive Liquid\u2013Liquid Microextraction","volume":"35","author":"Grindlay","year":"2020","journal-title":"J.
