Response surface methodology (RSM) idagwiritsidwa ntchito pofufuza njira ya nitric acid leaching process of waste Co Mo based hydrotreating catalyst.Cholinga cha phunziroli chinali kufotokoza CO ndi Mo kuchokera ku chothandizira chomwe chinagwiritsidwa ntchito mu zosungunulira monga zosungunulira m'madzi, kuti zithandize kuyeretsedwa ndi kubwezeretsanso, ndikuzindikira chithandizo chopanda vuto ndi kugwiritsa ntchito zinyalala zolimba, Reaction. kutentha ndi chiŵerengero cholimba-chamadzimadzi.Zomwe zidakhudzidwa kwambiri zidatsimikiziridwa ndi njira yoyankhira pamwamba, ndipo ma equation amitundu yamagawo ndi cobalt ndi molybdenum leaching rate adakhazikitsidwa.Pansi pamikhalidwe yabwino kwambiri yomwe idapezedwa ndi chitsanzocho, kuchuluka kwa cobalt leaching kunali kopitilira 96%, ndipo molybdenum leaching rate inali yopitilira 97%.Idawonetsa kuti magawo abwino kwambiri omwe amapezedwa ndi njira yakuyankha pamtunda anali olondola komanso odalirika, ndipo atha kugwiritsidwa ntchito kutsogolera njira yeniyeni yopangira.
