- kupu whakataki Na te herenga o te hiko hinu o te kainga me te hangarau para, he poto nga hua hinu e mahia ana e nga refineries auau i te maakete, na te mea he maha nga hua hinu whakaranu ka waipuke te maakete. Ko te penehīni whakangao rite te nuinga o te wa ka konatunatua ki te naphtha kakara (hinu marama) hei rauemi mata. Heoi, i te papamuri o te utu nui o nga rauemi mata me te whakanui ake i nga hua, ka whakamahia nga puhui aniline hei taapiri penehi kore tikanga. Kia tutuki ai te taurangi kounga o te penehīni me enei taapiri ki te paerewa penehīni motuka motumotu, hei tauira, ko te taapiri 1% (hautau papatipu) ka taea e N-methylaniline te whakanui ake i te tau octane ma te 2-4 wae [1]. Heoi ano, ko nga taapiri aniline ka raru pea ki te neke me te haumaru o nga waka, a ko nga N-methylanilines he pūhui hauota kei roto, ka piki ake te ihirangi o te hauota waikura i roto i te ngongo waka, ka pa he kino ki te taiao hau me te hauora tangata. . Ko nga waahanga matua o nga taapiri aniline ko te aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-methylaniline me N, n-dimethylaniline. I tenei wa, ko nga tikanga e korerohia ana mo te kimi i nga puhui methylaniline ko te naphthalene diethylamine spectrophotometry, te hau-hau hau-hauota chemiluminescence, te mahi teitei o te wai chromatography, me etahi atu [2-4]. Ko te naphthalene diethylamine spectrophotometry tuku iho ka whakararu i te hua whakatau na te puta mai o te tauhohenga taha, a, ko te tikanga HPLC ka pa ki te pokanoa o te matrix penehīni.
Ko te tikanga kimi hauota hauota-hauota chemiluminescence me whakarite he kaitirotiro hauota chemiluminescence utu nui ka taea te kimi hauota. Ko te paerewa a-motu i tuhia (kaore ano kia whakaputahia) "Gas Chromatography for the Determination of Oxycompounds and aniline Compounds in Gasoline" e whakaahua ana hoki i tetahi tikanga tātari ma te whakamahi i te whakawhiti a Deans i runga i nga pou polarity e rua ma te whakamahi i te katote katote katote katote ngawari me te utu iti. Mo tenei tikanga, kua whakaputaina e ThermoFisher Scientific he pepa Tono (Tuhipoka Tono C GC-50). Hei whakamaarama, ka whakauruhia e tenei pepa he tikanga pou kotahi tere ake i runga i te paerewa rohe DB37 / T-2650 i tukuna e Shandong Province i te tau 2015 [5]. Ko nga hua e whakaatu ana he ngawari tenei tikanga ki te whakahaere, he pai te tukurua me te tino tika. I te wa ano, i arotauhia te tikanga ki te whakaoti i te raruraru o te pokanoa o te inenga aniline na roto i te hanganga matrix matrix.
2. Te tirohanga whānui o te maapono o te tikanga I runga i te poupou polyethylene glycol (PEG), ka wehea nga pūhui aniline i roto i te penehīni automotive mai i te matrix penehīni, ka whakamahia te acetophenone hei paerewa o roto. Ko nga mea o roto o te aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-toluidine me te N, n-dimethylaniline i roto i te penehīni waka i whakatauhia e te chromatograph hau e mau ana ki te mura ahi ionization detector (FID), a ko te kukū o ia wahanga ko te ka tatauhia ma te tohu ki te paerewa o roto.
4: I tata nei, he nui te hiahia o te maakete, kei te haere katoa matou ki te whakaputa, ko te whakamahi hangarau ko te tikanga whakaputa tonu, ara, hau chromatography
Kei te mohio matou ka whakaaro koe ki a maatau anake ka tukuna atu e matou ki a koe te utu tino tika me te kounga pai. Tena koa tirohia to maatau rarangi ingoa.

7.whakatau
Ko tenei whakamatautau e pa ana ki te paerewa rohe DB37 / T-2650 o te Porowini o Shandong, me te tango i te kaitirotiro FID ki te kite i nga pūhui aniline i roto i te penehīni. He ngawari te tikanga, he pono te hua. Ahakoa ka whakamahia pea te pokanoa i roto i te tātaritanga tuturu, ka taea te karo i te pokanoa o te naphthalene i etahi taputapu penehīni ki te tātari aniline ma te arotau i nga tikanga.
