Nitrogen-15 Inogona Kuparadzaniswa Negasi Rinopinza Zvinhu Here?

Nhanganyaya

Nitrogen, chimwe chezvinhu zvakawanda zviri mumhepo, inoita basa rakakosha mumabasa akasiyana-siyana ehupenyu nemakemikari. Pakati pema isotopes ayo, nitrogen-15 (N-15) yave ichinyanya kutariswa nekuda kwehunhu hwayo hwakasiyana uye mashandisirwo ayo mukutsvaga kwesainzi. Masayendisiti ave achiongorora nzira dzakasiyana-siyana dzekuparadzanisa nekubatanidza N-15 nezvinangwa zvakasiyana-siyana. Muchinyorwa chino, tinoongorora mukana wekuparadzanisa N-15 uchishandisa gasi centrifuge, nzira inoshandiswa zvakanyanya pakuparadzanisa isotope. Tinokurukurawo nezvekushandiswa kunogona kuitwa uye zvinorehwa nekubudirira kwakadaro mumunda wekutsvagisa kwesainzi.

1. Kunzwisisa Kukosha kweNitrogen-15 Isotope

Nitrogen-15, isotope yenitrogen, yakasiyana nenitrogen-14 yakajairika nekuda kwekuvapo kweimwe neutron. Musiyano mudiki uyu wehuremu hweatomu unoita kuti N-15 ive chishandiso chakakosha muzvidzidzo zvakasiyana-siyana zvesainzi, zvinosanganisira biology, chemistry, uye ongororo yezvakatipoteredza. Vaongorori vanowanzo shandisa N-15 senzira yekutevera mafambiro enitrogen, kutora zvinovaka muviri mumiti, uye manyuko ekusvibiswa kwenitrogen. Zvisinei, kushomeka kweN-15 kunopa dambudziko guru pakuedza kuongorora isotopic kana kuita kuyedza kunoda huwandu hwakawanda.

2. Basa reGas Centrifuge mukuparadzaniswa kweIsotope

Kuparadzanisa maisotopu negasi kunosanganisira kupatsanurwa kwemaisotopu zvichibva pakusiyana kwawo nehukuru kuburikidza nesimba re centrifugal. Iyi nzira yakaratidza kubudirira kukuru mukuparadzanisa maisotopu akasiyana-siyana, akadai seuranium nekabhoni, pakugadzirwa kwesimba renyukireya uye kutsvagurudza kwezvekurapa, zvichiteerana. Zvichitevera kubudirira kwekuparadzira maisotopu negasi, masayendisiti anga achiongorora kushandiswa kwaro pakuparadzanisa N-15.

3. Matambudziko muKuparadzaniswa kweNitrogen-15 Isotope

Kunyange hazvo kupatsanurwa kwegasi kwaratidza kushanda mukupatsanura ma isotopes chaiwo, kupatsanurwa kweN-15 kunounza matambudziko akasiyana nekuda kwehunhu hwayo hwemaatomu. Nitrogen-15 yakakura ne0.37% chete kupfuura N-14, zvichiita kuti zviome kuwana kupatsanurwa kwakakosha kuburikidza nehunyanzvi hwemazuva ese hwekuparadzira gasi. Chinodiwa chekumhanya kwakanyanya uye kunyatsojeka mukupatsanura kunoita kuti nitro…
