Several common carrier electrolytes were implemented in an indirect UV detection method. The effect of electric field strength, injection volume, concentration of electro\u2010osmotic flow (EOF) modifier and UV\u2010absorbing agent in background electrolyte (BGE) was examined while peak height, peak area and noise were considered for optimization. The best results were obtained using a BGE that contained 35\u2009mM sodium chromate, 12\u2009mM free cyanide and 0.45\u2009mM hexamethonium bromide at pH 10.5. Free cyanide concentration was compared to that measured with the conventional silver nitrate titration method in solutions containing free cyanides and weak cyano\u2010complexes. The developed CE protocol proved very robust in capturing the concentration of free cyanides (4% error) unlike the titration method which exhibited substantial sensitivity to the interfering weak cyano\u2010complexes (38% error).<\/jats:p>","DOI":"10.1002\/jssc.201100095","type":"journal-article","created":{"date-parts":[[2011,5,19]],"date-time":"2011-05-19T06:00:18Z","timestamp":1305784818000},"page":"1568-1573","source":"Crossref","is-referenced-by-count":6,"title":["Determination of free cyanide and zinc cyanide complex by capillary electrophoresis"],"prefix":"10.1002","volume":"34","author":[{"given":"Elahe Ghasemian","family":"Langeroudi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catalin Florin","family":"Petre","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abdelaaziz","family":"Azizi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eric","family":"Proulx","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fa\u00ef\u00e7al","family":"Larachi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,5,19]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(97)00030-7"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1039\/an9921701145"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(02)00149-8"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9673(94)00826-4"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(96)01046-1"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/jssc.200800416"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-2670(99)00603-0"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0021-9673(01)86901-6"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chroma.2006.06.020"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-2670(00)01389-1"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/jhrc.1240160304"},{"volume-title":"The Chemistry of Gold Extraction","year":"1992","author":"Marsden J.
