They are often found in their liquid discharges. This work highlights the performance of an activated alumina-supported copper catalyst in the removal of cyanide by oxidation with hydrogen peroxide in aqueous solution. The influence of catalyst dose, initial molar ratio of hydrogen peroxide/cyanides, temperature, and catalyst reuse was studied. The activated alumina-supported copper significantly enhanced the reaction rate showing a good catalytic activity. The efficiency of cyanide elimination was increased after 30 minutes of oxidation from 48% to 98% by increasing the catalyst dose from 1 to 10 g/L. Rising the temperature from 30°C to 40°C promoted cyanide removal. The catalyst can be recycled four times and show good stability. The kinetics of cyanide oxidation was revealed to be pseudo-first order with regarding cyanides. The rate constants as well as the activation energy were determined.</p> </p></abstract><publication_date><month>01</month><day>22</day><year>2024</year></publication_date><pages><first_page>1</first_page><last_page>7</last_page></pages><publisher_item><identifier id_type="pii">gnest_05639</identifier></publisher_item><doi_data><doi>10.30955/gnj.005639</doi><timestamp>1715913196</timestamp><resource>https://journal.gnest.org/publication/gnest_05639</resource></doi_data></journal_article></journal></body></doi_batch> </div>
