ʻO ke ʻano mīkini ʻaila UV a me ka hoʻolauna kumu

Hoʻohana ka ʻaila ʻaila UV i ka n-hexane ma ke ʻano he mea hoʻoheheʻe a hoʻokō i nā koi o ke kūlana aupuni hou "HJ970-2018 Determination of Water Quality Petroleum by Ultraviolet Spectrophotometry".

Ma lalo o ke kūlana pH ≤ 2, lawe ʻia nā mea aila i loko o ka hāpana me ka n-hexane. Hoʻomaʻemaʻe ʻia ka extract e ka sodium sulfate anhydrous, a laila adsorbed e ka magnesium silicate e wehe i nā mea polar e like me nā aila holoholona a me nā mea kanu. Ana ʻia ka absorbance ma ka ʻāpana ultraviolet. Petroleum Ua kūlike ka ʻaila ʻaila a me ka waiwai o ka absorbance me ke kānāwai o Lambert-Beer, no laila ke kālailai nui ʻana i ka ʻaila i loko o ka wai.

He kūpono no ka hoʻoholo ʻana i ka ʻaila ma ka wai ʻili, ka wai honua a me ka wai kai. Hoʻohana nui ʻia i nā ʻōnaehana nānā kaiapuni, ʻoihana petrochemical, nā koleke a me nā kulanui, nā keʻena noiʻi ʻepekema, nā mea kanu hoʻomaʻemaʻe wai, mālama wai a me ka hydrology, nā mea kanu wai, petrochemical, hana pepa, lāʻau lapaʻau, kila, mahiʻai ʻO ka nānā ʻana i ke kaiapuni a me nā ʻoihana ʻē aʻe.
ʻO ka ʻokoʻa
ʻOkoʻa nā pae noi o ke ʻano UV a me ke ʻano infrared. He palena ʻike kiʻekiʻe ke ʻano infrared a kūpono no ka hoʻoholo ʻana i nā aila (ʻaila, holoholona a me nā aila mea kanu) i loko o ka wai. He kiʻekiʻe ka naʻau a me ka palena haʻahaʻa haʻahaʻa o ke ʻano UV a kūpono i ka wai o luna a me ka wai lepo. a me ka hoʻoholo ʻana o ka ʻaila i loko o ka wai kai.
ʻO ke ʻano infrared: He kiʻekiʻe ka naʻau o ke ʻano infrared, kūpono kūpono a me nā hopena quantitative, a hoʻohana i ka tetrachlorethylene ma ke ʻano he mea hoʻoneʻe e pani ai i ke kalapona tetrachloride e luku ai i ka papa ozone.
ʻO ke ala Ultraviolet: He kiʻekiʻe ka naʻau o ke ʻano ultraviolet a kūpono no ka hoʻoholo ʻana i ka ʻaila i loko o ka wai ʻili, ka wai honua a me ka wai kai. Hāʻawi ka maʻamau i ka hōʻoia ʻana o ka maikaʻi a me nā koi kaohi maikaʻi, hiki ke hōʻoia i ka ʻepekema a me ka pololei o ka nānā ʻana i ka ʻikepili i ka wā o ka hoʻohana ʻana i ke ʻano.
LH-OIL336, he UV oil detector i hoʻomohala kūʻokoʻa e Lianhua, hoʻokō me nā ʻano a me nā loina ʻike hou loa, hoʻohana i ka n-hexane ma ke ʻano he mea hoʻoheheʻe, a kūpono no ka hoʻoholo ʻana o ka ʻaila i loko o ka wai honua, ka wai honua a me ka wai kai.
Lianhua LH-OIL336 UV ʻaila mika he maʻalahi ke hana, loaʻa ka pololei pololei, ka ʻike kiʻekiʻe a me ka hana paʻa. Hiki iā ia ke hoʻokō i nā pono noi like ʻole o nā mea kūʻai aku a mālama i ka manawa o nā mea kūʻai aku i ka hoʻāʻo ʻana i ka wai. ʻO ke ana pololei o kēia mea ana aila ʻo 0.04-1ppmm. He 7-inihi ka ho'ākāka kiʻekiʻe e hoʻopā ai, hoʻohana i ka 20mm quartz cuvette no ke ana kala, a he paʻi wela i kūkulu ʻia e hiki ke mālama i nā ʻāpana ʻikepili he 5,000. He kiʻekiʻe kiʻekiʻe o ka automation, maʻalahi a wikiwiki hoʻi, a me ka hoʻohana ʻana i ka n-hexane no ka mea ʻo ka mea hoʻoheheʻe ʻana he mea aloha a palekana hoʻi. Loaʻa iā ia ka hana kaʻina hana maʻamau, ke kumukūʻai hoʻāʻo haʻahaʻa, ikaika anti-interference, wikiwiki hoʻāʻo wikiwiki, a hoʻomaikaʻi i ka pono o ka hana hoʻāʻo ʻana i ka wai.
