Calcium carbide slag bụ ihe mkpofu fọdụrụnụ nke mejupụtara calcium hydroxide mgbe hydrolysis nke calcium carbide gasịrị iji nweta gas acetylene. Nkwadebe nke ngwaahịa kemịkalụ sitere na carbide slag bụ maka ebumnuche imegharị ihe onwunwe, mmepe nke usoro ndụ akwụkwọ ndụ na mbelata ọnụ ahịa teknụzụ ga-abụ isi ihe nyocha n'ọdịnihu.

Ugbu a, nkwadebe nke nano-calcium carbonate site na calcium carbide slag gụnyere ụzọ atọ: calcination slaking, hydrochloric acid leaching na ammonium chloride leaching. Li Rui et al. jiri usoro calcination na pressure slaking mee ka calcium carbide slag meghachi omume na CO2 flue gas na pressurized carbonization reactor iji nweta spherical nano calcium carbonate carbonate (60nm). Usoro a abụghị naanị na-edozi mmetọ nke CO2 mkpofu gas, kamakwa ọ na-enweta ngwaahịa agbakwunyere bara uru; Liu Fei et al. nakweere usoro hydrochloric acid leaching, acidified calcium carbide slag na hydrochloric acid na pH=8, ma mee mmeghachi omume metathesis na sodium carbonate. Nsonaazụ gosiri na calcium carbide slag nke acidified ga-akwalite calcium carbonate whackers. Ihe omume nke agglomeration na alaka forked siri ike na-eduga na aragonitic calcium carbonate whackers nwere nkesa otu na oke akụkụ dị elu (30-60). Ma e jiri ya tụnyere ihe ndị dị ọcha nke ukwuu, achọpụtara na nano-carbonic acid nke e ji calcium carbide slag mepụta ruru ọkọlọtọ mba ma belata mmetọ nke carbide slag kpatara. Usoro a na-atụ aro ụzọ dị irè maka nkwadebe nke nano-calcium carbonate.

Zhu Min na ndị ọzọ jiri ammonium chloride gwọọ calcium carbide slag tupu ya, wee kwadebe nano-calcium carbonate site na carbonization. Nsonaazụ gosiri na mgbe njupụta nke ammonium chloride solution dị 8%, ọnụego ojiji nke calcium carbide slag karịrị 92%. Ụdị nano-calcium carbonate (nkezi nha nke ihe dị n'ime ya bụ 38nm), ịdị ọcha na ọcha nke ngwaahịa a nwetara site na usoro a ruru 99.65% na 98.60% n'otu n'otu, nke na-edozi nsogbu nke ịdị ọcha dị ala na ọcha na-adịghị mma nke ihe na-adịghị ọcha na nano-calcium carbonate kpatara, ọ bụkwa ezigbo ngwọta maka ngwa ụlọ ọrụ na-esote.
