Waikawa te ateneke: tātai hanganga matū. taonga tino mōrearea

Pānga o rerekē matū i runga i te tinana tangata, ko te rangirua. Te nuinga o tatou i matau pūhui ranei he kūpapa, ka whai wāhi pai i roto i te oraraa o te taata. Ko reira te mea he rōpū o matū, e tohu ana i te riri nui ki te hauora. E wehea ratou ki te maha akomanga. Whakaaro i roto i tenei tuhinga waikawa te ateneke - tetahi o enei matū paitini. E ai ki te whakarōpū whakaae tēnei wā, kua whakaurua te reira i roto i te piha haapiiraa tuarua o tiketike-mōrea, me ki chloroform, mata, me te konukōhatu pūhui. ako tatou i nga āhuatanga o te ateneke taipitopito waikawa atu.

hanganga rāpoi, me te āhua tinana o te mea

Tenei pūhui i raro i ngā āhuatanga noa he hanganga, tioata. Te riroraa i te tribasic, waikawa te ateneke, kua ai e rua tuarua, me te tātai H ₃ Aso ₄ tai waikawa. Hei tauira, konurehu gidroarsenat - K ₂ HAsO _4, konutai digidroarsenat - Nah ₂ Aso _4, lithium arsenate - Li ₃ Aso _4. waikawa te ateneke Calcining, te ateneke whiwhi gemipentoksid i huaina te ateneke pentoxide. Tona ma tioata mārama hanga i te puranga tangiwai, he ruarua wairewa i roto i te wai.

dissociation

H3AsO _4, me te waikawa formic me waihā mata ko tika kawehiko ngoikore. Ko te kupu, i roto i te tepu e toru taimau dissociation waikawa te waikawa ionization nui ortomyshyakovaya: 5.6 x 10 ^-3, 1.5 x 10 ^-7 me 3, 89 x 10 ^-12. tohu ine nui ēnei tohu te kaha waikawa. I roto i te runga i taimau dissociation i roto i te maha o ngā waikawa pararopi noho H ₃ Aso ₄ he tūranga i waenganui i te chromium me waikawa kakano. whakatakoto Whārangi Russian experimenters AL me I. L. Agafonovy faaiteraa pāngarau, ai tuatahi te hononga ahu me tamau dissociation tuarua o te waikawa te ateneke i te pāmahana mai i te 0 ° C ki te 50 ° C.

āhuatanga Rawa matū

Ko te tohu o te piti hāora o ngota te ateneke whakatu te rāpoi ngota waikawa, ko te 5. E pā ana te reira ki te meka e te pūhui iho i roto i te tauhohe matū ki ētahi atu matū whakaatu āhuatanga oxidizing. Ko te kupu, i roto i tona pāhekoheko ki te konutawa konurehu mahi rite te kaihoko whakaiti, i roto i te reo waikawa kitea tatou waikawa arsenious he H ₃ Aso ₃ i roto i te hua tauhohenga. A haamana'o na i taua waikawa te ateneke, ai _he tribasic tātai H ₃ Aso _4, me i konei, tauhohe ki turanga alkali rewakore ranei, ka taea e toru momo o tai hoatu a reira: reo, hydro- me digidroarsenaty. tauhohenga kounga ki Aso ₄ ^3- katote i roto i te matū tātari o te pāhekoheko iho he waikawa te ateneke ona tai ki tai hiriwa wairewa, pērā i pākawa ranei. Ka rite ki te hua o te mātakitaki rerenga Ag ₃ Aso ₄ tae kawhe.

tikanga Iodometric mō te faaotiraa o te waikawa te ateneke

I roto i te matū tātari, he mahi nui, ko te ki te kitea pūhui matū i roto i te rongoā. Ateneke waikawa, ngā āhuatanga matū i kōrero matou mua, e taea te kitea micromethod iodometry. Ki 1 ml o tona otinga ringihia te te taua rōrahi o 4n. waikawa pūhaumāota me te 1 ml o te 4% otinga o te pāhare pāporo konutawa. I hanga sesquioxide te ateneke rite ₂ E _3, o nei i raro i tino moni ine o tauhohenga ko tonu _te papatipu te taua, me te he rite ki te 0,5746 mg.

Ko te kaha oxidizing o te waikawa te ateneke

Ka rite ki mohiotia te, H ₃ Aso _{4 rite} waikawa orthophosphoric, he kaha reo kawehiko. He deliquescent ma ona tioata mārama me e whakatakoto 2H ₃ Aso ₄ x H ₂ O. ona tai i hanga ki te konganuku alkali (rite toharite, me te waikawa), i roto i wairewa waiwai i te pH nui atu 7. Arsenates lithium, pāhare pāporo, te konutai me te haukinia ngāwari wairewa i roto i te wai, a kahore e te toenga o te tote Middle memeha i roto i te reira. waikawa te ateneke - he oxidizer pai. I roto i te tauhohe pitihāoratanga, kua whakahokia reira ki te waikawa arsenous arsine ranei.

H ₃ Aso ₄ ⁺ 2e + 2H + = H ₃ Aso ₃ + H ₂ E

H ₃ Aso ₄ ⁺ 8e + 8H + = Ash ₃ + 4H ₂ E

I tua atu, waikawa te ateneke ohie oxidizes ngā konganuku, konutawa sulfite me te waikawa, me te hauwai sulfide.

Te faaineineraa o te waikawa te ateneke

I raro i ngā āhuatanga taiwhanga, Ka taea e H ₃ Aso ₄ kia whiwhi mā te tauhohe i sesquioxide te ateneke ki te waikawa hauota i raro i whakawera. kitea nga hua waikura Sinks me H ₃ Aso _4. Ko tētahi atu tikanga o te whakarite - ko te whakakorenga i te wai o te waikura te ateneke. Auau whakamahia ki te whiwhi i te reira hāora tukutahi, me te tauhohenga wai trialkilarsenitov te tahu ki te 50 ° C ki te otinga o te hauwai. Wä, nekehia te ranunga tauhohe te i te wai, me te waipiro. Ko reira te otinga mimiti me te waikawa te ateneke viivii ore teitei whiwhi. I roto i te natura, i te rauemi raw mō te waikawa te ateneke he kohuke arsenolite me arsenopyrite, e te hunga taonga i roto i putunga o Chelyabinsk me Chita Region o te Russian Federation.

H3AsO4 Taupānga

Homai te meka e ortomyshyakovaya waikawa ko tetahi o te paihana kaha. He iti tona tono i roto i te ahumahi, me te ora rā. tote atu noa - arsenates, tona tāoke he nui iti ake i taua o te nuinga o H ₃ Aso _4. Ko te kupu, i roto i te ahumahi tukatuka rakau ki te konutea pākawa me pentachlorophenol konutai tote, Kei te whakamahia te waikawa te ateneke mo te maimoatanga o te rakau. whakaiti i tēnei tikanga te ngaronga i te whakangaromanga o te mate cellulose fungal me ngā torongū o ngā pītara, borers rakau. I roto i te rongoa H ₃ Aso ₄ whakamahia te i roto i te "Atoxil" teuteu mo te maimoatanga o te mate protozoal, pērā i giardiasis, balantidiasis, isosporiasis.

Me kï reira e enei mate i roto i nga tau tata nei, kua nui haere te taupori pangia tino. He maha ngā take - hei tauira, mate i te kai kei roto pua hātare, e ngau pepeke moepuku ranei. whakamahia waikawa te ateneke te rite tīmata rauemi i roto i te tukanga whakaputa o mōhiti optical, me te i roto i te engineering hiko. H pārōnaki ₃ Aso ₄ - tona konutai tote, Kei te pai tono i roto i te Dermatology me kohi. Pūhui whakamahia i roto i te ateneke (whakapiri te ateneke) niho rite te tarukino whakamahia mō te tukupu te tūtohutanga mamae o te karere matia ki runga ki te tango i te awa niho.

Ko te mahi o te waikawa i runga i te tinana tangata

Ka rite ki whakahuatia mua, H ₃ Aso ₄ ngā i roto i te mōrearea nui haere tuarua piha - matū tino kino. Whakaaro inenga whakamate o rua te waikawa me ona tai i roto i te whānui i te 15 ki te 150 mg ia manokaramu o te tinana tangata. Āpiti atu ki te pānga paitini noa, waikawa te ateneke ai necrosis o te kiri, me kiriuhi mucous o whekau: pūkahukahu, puku, whēkau.

I roto i te taiwhanga, i roto i te ngā, me arsenate me H ₃ Aso ₄ hiahiatia te ki te whakamahi i karapu tiaki, ka whakamana i ngā ratou i raro i te autahu'araa fume. I roto i te take o te taumata o te tāoke pūtau takahia tona pūnaha whākōkī, rite inactivation o whākōkī. I roto i te tangata, arata'i poisoning arsenate ki paresis ara pāpāngia ranei. I roto i te matepukupuku hahau ki te hanganga ture-kore ki regimens dosing o taero me take poisoning miarsenolom tuhia novarsenolom. āwhina Tuatahi mō Mariao poisoning o te waikawa te ateneke he tonu lavage pekitīlia (hei tauira, te konutai unitiola takawai hāorarua ranei taka).

Kia kore ai täkihi whakapeka, whakaritea tātari toto te. Ka rite ki te raau haunga unitiola 5% otinga, he reira taea ki te whakamahi i safener Strizhevskaya. I mua i ki te taenga o te whawhati tata āwhina tuatahi i te kāinga whakaiti taea te whakamahi i te taumata o te haurangi otinga waikawa citric, ka kaha ai ruaki me te horoi puku. kia kawea mehua haumanu katoa i roto i roto i te hanganga ture ki te moenga okiokinga tino i raro i te tirotiro hauora.
