MA-202U (Macroporous Strong-Base Anion Exchange Resin)

MA-202U (Macroporous Strong-Base Anion Exchange Resin)

MA-He kūlana kiʻekiʻe ʻo 202U, kūpale kūpilikiʻi, macroporous, ʻAno I, kēpau pāʻālua anion paʻa i hoʻolako ʻia i ke ʻano chloride ma ke ʻano he mākū, paʻakikī, ʻaʻano, ʻāpana poepoe. Hoʻohana ʻia ka kēpau no ka unuhi ʻana o ka uranium mai ka ʻenehana hāpai hānai in-situ leaching ʻenehana.

ʻO Uranium kahi hanana radioaktif nāwaliwali maoli. Hiki i nā pae kiʻekiʻe o ka uranium i ka wai ke hoʻonui i ka makaʻu o ka maʻi ʻaʻai a me nā hōʻino puʻupaʻa. ʻO ka hapa nui o ka uranium i lawe ʻia e ka meaʻai a mea inu paha e ke kino o ke kanaka e excreted, akā lawe ʻia kekahi mau kālā i ke kahe o ke koko a me nā puʻupaʻa.

ʻO Uranium ka radionuclide, ʻoi aku paha i ka wai lepo ma mua o ka wai o ka honua, a pinepine

loaʻa pū me ka radium. Pono paha ka hoʻohaʻahaʻa ʻana i nā wai pilikia i ka mālama ʻana no ka hemo ʻana o ka uranium a me ka radium.

Aia ka Uranium i loko o ka wai e like me ka ion uranyl, UO22 +, i hana ʻia i mua o ka oxygen. Ma ka pH ma luna aʻe o ka ʻeono, aia ka uranium i loko o ka wai hiki ke inu ʻia ma ke ʻano he uranyl carbonate complex. He pilina koʻikoʻi kēia ʻano uranium no nā resion anion kahua ikaika.

ʻO ke ʻano pili o ka pilina o nā anion base resins no kekahi mau ion maʻamau i ka wai inu e hōʻike i ka uranium ma ka piko o ka papa inoa.

Hoʻōla Hou

I mea e hoʻoulu hou ai i ka uranyl carbonate he mea nui ia e lawa ka kiʻekiʻe o ka regenerant ma ka moena resin e hoʻohuli a hōʻemi paha i nā pili pili i nā pae ʻae ʻia a e hoʻohana i ka manawa hou a me ka manawa hoʻopili. ʻO Sodium chloride ka regenerant maʻamau.

ʻO ka noʻonoʻo ma luna o 10% NaCl, ma nā pae regenerant o 14 a 15 lbs. no ka cu. lawa lawa ʻo ft. E hoʻonui kēia ana ma 50% o ka uranium i hōʻiliʻili ʻia mai ke kēpau. E haʻahaʻa ka leakage ma o nā lawelawe lawelawe me ka ʻole o ka hoʻoulu hou ʻana ma muli o ke koho kiʻekiʻe loa i ka wā o ka lawelawe lawelawe. ʻAʻole pono nā leakage i nā pae hoʻoulu hou o 15 lbs. o ka sodium chloride ma ka cu. ft. ma nā kukuna o 10% a ʻoi aku paha me ka liʻiliʻi o ka manawa hoʻopili o 10 mau minuke i ka manawa o ka hana hou ʻana.

Ka palekana a me ka lawelawe ʻana

ʻO ka ʻōpala hou mai ka ʻōnaehana hoʻohemo uranium kahi ʻano concentrated o ka uranium a pono e hoʻolilo kūpono. No ka mea hale, hoʻokuʻu ʻia ka hopena i hoʻolilo ʻia i ke ala like e hoʻokuʻu ʻia ai ka brine softener, ʻo ka nui o ka uranium e hōʻea ana i ka wahi hoʻolei he mea like inā ʻaʻole kahi unuhi uranium i kahi. Eia nō naʻe, pono e nānā i nā lula no kahi wahi i hāʻawi ʻia.

ʻO ka hoʻolei ʻana o ka kēpau uranium-laden e pono e noʻonoʻo i ka nui o ka radioactivity i loaʻa i ka pāpāho.

Hoʻonohonoho ka US Department of Transportation i ka halihali a me ka lawelawe ʻana i nā ʻōpala radioactive haʻahaʻa haʻahaʻa. ʻOi aku ka liʻiliʻi o ka uranium a no laila ʻoi aku ka kiʻekiʻe o nā pae i ʻae ʻia ma mua o ka radium. ʻO ka pae i hōʻike ʻia no ka uranium ʻo ia ka 2000 picoCury ma ka gram o ka pāpāho.

Hiki ke helu ʻia nā throughputs anticipated e kāu ion resin supplier. Hiki i nā noi ke komo i nā puke ʻoihana theoretical i ʻoi aku ka nui ma mua o 100,000 mau moena moe (BV), ʻoiai nā pōʻaiapili lawelawe ma ka lawelawe hou ʻana ma kahi o 40,000 a 50,000 BV. ʻOiai e hoʻowalewale nei e holo i ke kēpau i ka manawa hiki ke hiki i nā noi o ka manawa hoʻokahi, pono e noʻonoʻo i ka nui o ka uranium i hōʻiliʻili ʻia a me nā pilikia hoʻolei hope.
