I-Response surface methodology (RSM) yasetshenziswa ukutadisha inqubo ye-nitric acid leaching of waste Co Mo based hydrotreating catalyst. Inhloso yalolu cwaningo bekuwukwethula i-CO ne-Mo kusukela ku-catalyst echithiwe ibe yi-solvent ngendlela yokuncibilika emanzini, ukuze kube lula ukuhlanzwa nokululama okulandelayo, kanye nokubona ukwelashwa okungenangozi kanye nokusetshenziswa kwensiza yemfucumfucu eqinile, Reaction. izinga lokushisa kanye nesilinganiso esiqinile-soketshezi. Izici eziyinhloko ezithonyayo zanqunywa indlela yendawo yokuphendula, futhi isibalo semodeli yemingcele yenqubo kanye nenani le-cobalt ne-molybdenum leaching yasungulwa. Ngaphansi kwezimo ezinhle zenqubo etholwe imodeli, izinga le-cobalt leaching lalingaphezu kwama-96%, futhi izinga le-molybdenum leaching lalingaphezu kwama-97%. Ibonise ukuthi amapharamitha wenqubo alungile atholwe ngendlela yokuphendula yayinembile futhi inokwethenjelwa, futhi ingasetshenziswa ukuqondisa inqubo yokukhiqiza yangempela.
