Nickel Oxide Powder

(Nickel Oxide Powder)

NiO ufa amagwiritsidwa ntchito mu aloyi wa nickel, salt, catalysts, cell cell cell ndi mankhwala ena komanso ma ceramic glazes, frits ndi colorants. Zonyansa zodziwika bwino ndi cobalt, mkuwa, chitsulo ndi sulfure pamlingo wa 1% kapena kuchepera.

Kuwonekera kwa ntchito ndi chilengedwe ku NiO wobiriwira (NiO-g) kwanenedwa ku USA. Pafupifupi matani 4000 a mankhwala a NiO amapangidwa chaka chilichonse.

Mu kafukufuku wazaka ziwiri wa National Toxicology Program mu makoswe a F2/N, carcinogenicity ina inanenedwa ndi kutupa kosatha popanda fibrosis. Minofu yomwe idakhudzidwa kwambiri inali mapapo, bronchial lymph nodes ndi thymus. Kusintha kwa ziwalozi kunali kofanana ndi nyama zomwe zimakhudzidwa ndi mawonekedwe otsika aerosol ku NiO-g.

Mawonekedwe apamwamba a XPS amatsimikizira kukhalapo kwa crystalline NiO yokhala ndi nsonga zazikulu za 2.41, 2.09, 1.48, 1.26 ndi 1.21 A (d) ndi kuchulukitsa kwa Ni 2p ndi O 1s. Kuphatikiza apo, XRD idawonetsa oxide yopyapyala ya NiO-g yomwe imakutidwa ndi Ni2O3 yolemera kwambiri kapena Ni(OH)2 surface oxide.

Deta yotulutsidwa ya ufa wa NiO-g wowonekera unatsimikiziridwa m'madzi opangidwa ndi kufunikira kwa njira ziwiri zazikulu zowonetsera poizoni wa nickel kuphatikizapo thukuta lochita kupanga (ASW) ndi lysosomal fluid (ALF). Pambuyo powonekera, nickel yomwe inatulutsidwa kuchokera ku ufa wa Ni metal inasungunuka mofulumira kwambiri ndipo inali yochepa mu ALF kusiyana ndi ASW, kusonyeza kuti nickel yomwe inatulutsidwa inali makamaka ntchito ya kusungunuka kwa mankhwala m'malo mwa electrochemical kapena complexing process.

Tsatanetsatane wa tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'onoting'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'onoting'ono, kuphatikiza kusanthula kwa kinetics kutulutsa kwa faifi tambala kuchokera ku ufa wa chitsulo cha nickel poyerekeza ndi ufa wochuluka wa nickel oxide, ndi gawo lofunikira pakumvetsetsa momwe ma fakisi achitsulo a nickel akukula. Kufufuza kumeneku ndi chida chamtengo wapatali chodziwira kuyambiranso kwa ufa wochuluka ngati njira yowonjezera chitetezo chawo.
