Tsvina muMethylene Blue neNzira dzeKuongorora

Boka reongororo dzesimbi dzinorema rinogona kuratidza chimwe chinhu chinobatsira pamusoro pesampuli yemethylene blue: kuwanda kana miganhu yakashumwa yezvinhu zvemakemikari zvakaongororwa. Harigoni kuratidza kuti mune Azure B yakawanda sei, kana paine zvinonyungudutsa zvakasara, kana kuti bhodhoro rakagadzirwa rine kuwanda kwakanyorwa pariri. Mibvunzo iyoyo inoda kuyerwa kwakasiyana.

Chinofanira kuitwa ndechekubatanidza chirevo chimwe nechimwe chemhando neongororo inogona kuchitsigira. Tanga nechinhu chataurwa nezita, sampuli, uye nzira yekuongorora. Kuoneka kwebhuruu chinhu chinoonekwa, kwete chinotsiva nhevedzano iyi yeuchapupu.

Zvinhu zvitatu zvakasiyana pamakemikari zvinotarisirwa kuyerwa

Tsvina yezvinhu zvemakemikari inosanganisira mutobvu, cadmium, arsenic, nemekiyuri. “Simbi dzinorema” musoro unowanzoshandiswa mumishumo, kunyange zvazvo arsenic iine zvimiro zviri pakati pesimbi nezvisiri simbi. Ongororo yakanangana nechinhu chimwe nechimwe chemakemikari inopa ruzivo rwakawanda kupfuura musoro wacho: boka reongororo yezvinhu zvina rine zvinhu zvina zvakataurwa nezita zvarinoyera, kwete tsvina yose ingangovapo.

ICP-MS inoreva kuongorora kunoyera maion maererano nehuremu hwawo kuchishandisa plasma inogadzirwa nekubatanidzwa kweinduction. Sampuli yagadzirirwa inopinda muplasma inopisa, uye mudziyo unoyera maion maererano nereshiyo yehuremu hwawo kuchaji yemagetsi yawo. Tsananguro yeEPA yeICP-MS inotsanangurawo kukosha kwekugadzirira sampuli nekudzora zvinokanganisa kuyerwa. Zita renzira yekuongorora roga hariratidzi kuti imwe sampuli yemethylene blue yakagadzirirwa uye yakayerwa nemazvo. Maitiro eEPA ekuongorora zvakatipoteredza ataurwa pano kuti atsanangure nzira yacho, kwete senzira inodiwa pakuongorora mishonga.

Madhayi ane hukama mamorekuru ane kabhoni ane hukama hwemakemikari nemethylene blue. Azure B ndechimwe chezvinhu izvi. Kuyera maatomu emutobvu hakugoni kuratidza huwandu hwedhayi iri. Nzira yekuparadzanisa zvinhu nechromatography inofanira kusiyanisa zvinhu zvakakodzera, ichizvizivisa nekuyera huwandu hwazvo nenzira dzakakodzera. Somuenzaniso, chidzidzo cheLC-MS/MS chaKim nevamwe vake chakayera methylene blue neAzure B zvakasiyana muplasma yeropa remakonzo. Chidzidzo ichocho chinoratidza kupatsanurwa kwezvinhu pakuongorora musampuli yerudzi rwakanga rwasimbisirwa nzira yacho; hachisimbisi kururama kweongororo yehuwandu muupfu hwemutengesi.

Azure B inogona kuvawo chinhu chinogadzirwa nemuviri paunochinja chimwe chinhu kuburikidza nemetabolism. Basa rayo mumuviri haribvisi kudiwa kwekudzora huwandu hwayo muchinhu chinotangira kugadzirwa. Gwaro rakasiyana pamusoro peAzure B setsvina uye sechinhu chinogadzirwa nemetabolism rinotsanangura mamiriro iwayo.

Zvinonyungudutsa zvakasara rimwe boka retsvina ine kabhoni. Chitsauko cheUSP chezvinonyungudutsa zvakasara chinotsanangura makemikari anoshanduka nyore kuva mhute, anoshandiswa kana kugadzirwa panguva yekugadzira, angangosara muchinhu. Chromatography yegasi, kazhinji ichishandisa sampuli yemhute iri pamusoro pechinhu, inzira inowanzoshandiswa. Munzira yeMilliporeSigma yeGC inoshandisa mhute iri pamusoro pesampuli, mhute iri pamusoro pesampuli inopinzwa mumudziyo kuti ipatsanurwe. Izvi zvinopindura mubvunzo wakasiyana newunopindurwa nemufananidzo wemigumisiro yechromatography yemadhayi ane hukama.

Mufananidzo webutiro unoratidza mapoka aya eongororo. Zviratidzo zvemadhayi zvakanyorwa mazita zvinoratidza makemikari anotarisirwa kuyerwa, zvisingaratidzi huwandu hwawo kana kutevedzana kwenguva yaanobuda muchromatography.

Kuenzanisa kune tsananguro kubva mumishumo miviri chaiyo

Zvisingakuudzi migumisiro yekuyera huwandu nekuomesa

Ongororo yehuwandu inoyera zviri muchinhu ichienzanisa nechiyero chakatsanangurwa uye hwaro hwekuverenga hwakatarwa. Chidimbu chinowanikwa kuruzhinji chegwaro reUSP remethylene blue chinotsanangura 97.0% kusvika 103.0% pachishandiswa hwaro hwechinhu chakaomeswa. Hachiratidzi gwaro racho rose, saka chidimbu ichi hachigoni pachacho kusimbisa zvose zvinonzi zvinodiwa nebhuku rezviyero.

Mugumisiro uri pedyo ne100% hausi rondedzero inoratidza kuti tsvina yose haipo. Uye haufaniri kubvisa huwandu hwetsvina imwe neimwe yakashumwa pa100 wotarisira kuti mhinduro ibudise mugumisiro weimwe ongororo yehuwandu. Kusiyana kwemapinduriro emidziyo yekuongorora, hwaro hwekuverenga, uye kusava nechokwadi pakuyera zvinogona kuita kuti kuverenga ikoko kusava nezvakwakanoreva. Gwaro rehwaro hwekuverenga huwandu hwemethylene blue rinotsanangura musiyano uyu zvakadzama.

Methylene blue inowanikwawo iri mumafomu ane mamorekuru emvura. Kurasikirwa nehuremu pakuomesa kunoyera huremu hunobviswa pasi pemamiriro ekuomesa akatarwa; hakusi kuyerwa kwakanangana nesimbi imwe kana dhayi rimwe chete. Zvasara mushure mekupiswa zvinoyera chinosara mushure memaitiro ekupisa akatarwa. Hapana pane nhamba idzi inozivisa zvose zvakakonzera mugumisiro wacho. Ongororo idzi dzinowedzera ruzivo pamwe chete nekuyerwa kwetsvina dzakanangana nezvinhu zvakati.

Verenga miganhu, mayuniti, nezvinofukidzwa pamwe chete

Pazvikamu zvinoyerwa maererano nehuremu, 1 ppm yakaenzana ne1 maikirogiramu pagiramu, uye 1% yakaenzana ne10,000 ppm. Izvi zvinotsanangura kuchinjwa kwemayuniti eMacsen mutafura. Usatsiva mayuniti ehuremu pahuremu neehuremu pavhoriyamu usina kuzvitaura paunenge uchienzanisa upfu nechinhu chakanyungudutswa mumvura.

Mugumisiro wakanyorwa kuti “<0.05 ppm” unopa muganhu. Kuti unzwisise kugona kwenzira yekuongorora kuyera huwandu hushoma, bvunza kana muganhu iwoyo uri wekukwanisa kuona kuti chinhu chiripo, wekukwanisa kuyera huwandu hwacho, kana wekushuma migumisiro. Mugumisiro wekufungidzira wekuti “<5 ppm” haungaratidzi kuzadziswa kwemuganhu mukuru we0.5 ppm: kuwanda kuri pakati penhamba idzodzo kungava pasi pemuganhu wakashumwa asi kuchidarika zvinobvumirwa.

Kusarudzwa kwezvinhu zvemakemikari kunodawo kunzwisiswa maererano nemamiriro acho. Hurongwa hweICH Q3D hwetsvina yezvinhu zvemakemikari hunoshandisa kuongorora njodzi kugadzira nzira dzekudzora zvigadzirwa zvemishonga. Mugumisiro wakanaka wezvinhu zvina haufaniri kutsiva kuongororwa kwezvinobva mukugadzira zvinokodzera kufungwa nezvazvo uye chigadzirwa chiri kuitirwa. Muganhu wekuwanda une zvaunoreva mukati mezvinodiwa izvozvo, kwete sechirevo chekuchengeteka pakushandiswa kwese.
