2. A na-eji Nano-manganese dioxide (HN-MnO2-50) eme ihe na batrị zinc-manganese; ụdị alkaline manganese dabara adaba maka batrị alkaline zinc-manganese, ụdị alkaline alkaline manganese nke na-enweghị mercury dabara adaba maka batrị alkaline zinc-manganese dioxide. Nano manganese dioxide (HN-MnO2-50) bụ ihe na-eme ka batrị ghara ịdị mma. Ma e jiri ya tụnyere batrị kpọrọ nkụ nke ndị nkịtị na-emepụta.manganese dioxide,O nwere ihe ndị dị ka ikike mwepụta buru ibu, ike ịrụ ọrụ, obere nha, na ndụ ogologo. Ya mere, Nanomanganese dioxide aghọwo ihe dị oke mkpa maka ụlọ ọrụ batrị.
3. Na mgbakwunye na ịbụ isi ihe eji emepụta batrị, a na-ejikwa nanometer manganese dioxide (HN-MnO2-50) eme ihe n'ọtụtụ ebe n'ọhịa ndị ọzọ, dịka: dị ka ihe na-eme ka ihe dị mma na-arụ ọrụ na mmepụta kemịkalụ dị nro na dịka ihe na-eme ka ihe magnetik dị nro nke manganese-zinc ferrite dị nro.
4. Nano-manganese dioxide (HN-MnO2-50) nwere ikike dị ike nke na-eme ka ihe dị ọcha, oxidation/mbelata, mgbanwe ion na absorption. Mgbe a gwọchara ya ma kpụzie ya, ọ bụ ihe nzacha mmiri dị mma nke nwere arụmọrụ zuru oke, ma e jiri ya tụnyere ihe nzacha mmiri a na-ejikarị eme ihe dịka carbon na zeolite, ọ nwere ike ịgbanwe agba na iwepụ ígwè.
