He aha nā ʻano lapaʻau maʻamau no ka cyanide - loaʻa ka wai ʻōpala?

I kēia manawa o ka hoʻomaikaʻi mau ʻana i nā pae hoʻokele kaiapuni a me nā koi paʻakikī, nui nā kahua e hoʻohana ana i nā cyanides e hana i kahi nui o nā wai ʻōpala ʻino. Inā ʻaʻole hoʻohana pono ʻia, hiki iā ia ke hoʻoweliweli i ke olakino kanaka. No ka hoʻokō ʻana i nā pahuhopu ʻelua o ka ʻōpala ʻole a me ka ʻino ʻole, hiki ke hoʻohana ʻia nā ʻano hana hana hou e hoʻoponopono ai i kēia pilikia.

Keʻano Acidification

ʻO ke kumumanaʻo nui o kēia ʻano hana, ʻo ia ka hoʻohui ʻana i ka waikawa sulfuric i ka wai hoʻoheheʻe cyanide e like me ka wai hoʻoheheʻe Sodium cyanide a hoʻoponopono i ka pH a puni 1.5. Hoʻololi kēia i ka CN - i HCN. ʻOiai he haʻahaʻa loa ke kiko paila o HCN, he 26.5 ℃ wale nō, hiki iā ia ke pakele mai ka hopena ma ka mahana o ka lumi. Hoʻokomo ʻia ke kinoea HCN i pakele i loko o kahi mea hoʻomoʻa a omo ʻia e kahi hopena alkaline (sodium hydroxide a i ʻole ka hopena calcium hydroxide). ʻO ka hopena, loaʻa kahi hopena cyanide 20% - 30%, hiki ke hana hou ʻia.

Ion - Keʻano hoʻololi

Loaʻa i nā resins anion-change kahi pilina ikaika no nā ions metala-cyanide complex like ʻole i loko o ka wai hoʻoneoneo e loaʻa ana i ka cyanide. Ma o nā kaʻina hana o ka adsorption a me ka desorption, hiki ke wehe ʻia nā Cyanide a me nā metala waiwai nui i loko o ka wai hoʻoneoneo. ʻO ka pōmaikaʻi o kēia ʻano hana, ʻo ia ka maikaʻi a me ke kūpaʻa o ka wai i hoʻomaʻemaʻe ʻia. Eia nō naʻe, he liʻiliʻi nā nui o nā ʻāpana o nā resins anion-change a ʻaʻole lawa ka ikaika mechanical. Eia kekahi, he paʻakikī ke kaʻina hana, me ka paʻakikī hana kiʻekiʻe a me nā kumukūʻai kiʻekiʻe.

ʻO ke ʻano o ka hoʻohana ʻana i ka carbon adsorption

Loaʻa i ka carbon activated kahi ʻano microporous waiwai a me ka hydrophobicity ili, a he pilina ikaika loa ia no nā mea ʻona i ka wai. No laila, ʻo ke ʻano o ka carbon adsorption i hana mau ʻia kekahi o nā ala kūpono loa no ka wehe ʻana i nā mea ʻawaʻawa haʻahaʻa i ka wai. ʻO ka hopena adsorption o ka carbon activated e hilinaʻi nui ʻia i kona mau pores kūloko a me kahi ākea kikoʻī nui.

I mea e hōʻoia ai ʻaʻole i liki nā cyanide e like me ka Sodium Cyanide , hoʻāʻo pinepine nā mea nānā i ka maikaʻi o ka wai e hoʻoholo ai i ka laulā o ka haumia cyanide. Inā pono, e hoʻonui ʻia ka wahi hoʻolaha. Pono nā mea nānā a me nā limahana mālama ma ke kahua e ʻaʻahu i nā mīkina lima pale i ka ʻaila rapa.

I ka hopena, he mea nui ka mālama pono ʻana a me ka hana hou ʻana i nā wai ʻōpala Cyanide no ka palekana o ke kaiapuni a me ka mālama ʻana i nā kumuwaiwai. Ma ka hoʻokō ʻana i kēia mau ʻano hana a me ka hōʻoia ʻana i ka nānā pono ʻana, hiki iā mākou ke hōʻemi i nā hopena maikaʻi ʻole o nā ʻōpala i loaʻa ka cyanide i ke kaiapuni a me ke olakino kanaka.
