- kupu whakataki Nā te herenga o te pūngao hinu ā-rohe me te hangarau whakamahine, he iti noa ngā hua hinu e whakaputaina ana e ngā whare whakamahine noa i te mākete, ā, he nui ngā hua hinu whakaranu e waipuke ana i te mākete. Ko te nuinga o te wā, ko te penehīni whakaranu noa e whakaranua ana ki te naphtha kakara whakaranu (hinu māmā) hei rauemi mata. Heoi, i te papamuri o te teitei o ngā utu rauemi mata me te whakanui ake i ngā hua, he maha ngā wā ka whakamahia ngā matū aniline hei tāpiri penehīni rerekē. Hei whakatutuki i te taupū kounga o te penehīni me ēnei tāpiringa ki te paerewa penehīni motuka ā-motu, hei tauira, mā te tāpiri i te 1% (wāhanga papatipu) N-methylaniline ka taea te whakanui ake i te tau octane mā te 2-4 waeine [1]. Heoi, he tūponotanga pea ngā tāpiri aniline ki te nekeneke me te haumaru o ngā waka, ā, ko ngā N-methylaniline he matū kei roto he hauota, ka piki ake te ihirangi o ngā waikura hauota i roto i te hauhautanga motuka, ka pā kino ki te taiao hau me te hauora o te tangata. Ko ngā wāhanga matua o ngā tāpiri aniline ko te aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-methylaniline me te N, n-dimethylaniline. I tēnei wā, ko ngā tikanga e pūrongohia whānuitia ana mō te kimi i ngā matū methylaniline ko te naphthalene diethylamine spectrophotometry, te kimi hau chromatography-hauota chemiluminescence, te chromatography wai mahi teitei, me ētahi atu [2-4]. Ka whakararu te naphthalene diethylamine spectrophotometry tuku iho i te hua whakatau nā te puta o te tauhohenga taha, ā, ka pāngia te tikanga HPLC e te whakararuraru o te matrix penehīni.
Ko te tikanga kimi hau chromatograph-hauota chemiluminescence e hiahia ana ki te whakarite i tētahi taputapu kimi hauota chemiluminescence utu nui ka taea te kimi i te hauota. Ko te paerewa ā-motu kua tuhia tata nei (kāore anō kia whakaputaina) "Gas Chromatography for the Determination of Oxycompounds and aniline Compounds in Gasoline" e whakaahua ana hoki i tētahi tikanga tātari mā te whakamahi i te pana Deans ki ngā pou polarity e rua e rerekē ana mā te whakamahi i te taputapu kimi mura hauwai ion noa me te iti te utu. Mō tēnei tikanga, kua whakaputa a ThermoFisher Scientific i tētahi pepa Tono (Application Notes C GC-50). Hei whakangawari, ka whakaurua e tēnei pepa tētahi tikanga pou kotahi tere ake i runga i te paerewa ā-rohe DB37/T-2650 i tukuna e te Porowini o Shandong i te tau 2015 [5]. E whakaatu ana ngā hua he ngāwari te whakahaere i tēnei tikanga, he pai te whakahokinga me te tino tika. I taua wā anō, i arotauhia te tikanga hei whakaoti i te raruraru o te pokanoa o te ine aniline mā te hanganga matrix penehīni.
2. Tirohanga Whānui o te Mātāpono o te Tikanga I runga i te pou polyethylene glycol porowhita (PEG), i wehea ngā matū aniline i roto i te penehīni motuka mai i te matrix penehīni, ā, i whakamahia te acetophenone hei paerewa ā-roto. Ko ngā ihirangi o te aniline, N-methylaniline, o-methylaniline, p-methylaniline, m-toluidine me te N, n-dimethylaniline i roto i te penehīni motuka i whakatauhia mā te chromatograph hau kua rite ki te pūoko ionization mura (FID), ā, i tatauhia te kukū o ia wāhanga mā te tohutoro ki te paerewa ā-roto.
4: I ēnei rā, he nui rawa te tono a te mākete, kei te whakapau kaha mātou ki te whakaputa, ko te whakamahi i te hangarau he tikanga whakaputa tonu, arā, ko te chromatography hau.
E mārama ana mātou ka whakaarohia mātou e koe, ko mātou anake ka tuku atu i te utu tino whaitake me te kounga pai rawa atu. Tena tirohia tā mātou rārangi pukapuka.

7.whakatau
E pā ana tēnei whakamātautau ki te paerewa ā-rohe DB37/T-2650 o te Porowini o Shandong, ā, e whakamahi ana i te pūoko FID hei kimi i ngā matū aniline i roto i te penehīni. He māmā noa te tikanga, ā, he pono te hua. Ahakoa ka taea te whakamahi i te pokanoa i roto i te tātaritanga tuturu, ka taea te karo i te pokanoa o te naphthalene i roto i ētahi papa penehīni ki te tātaritanga aniline mā te arotau i ngā āhuatanga.
