Sulphate ions: tabbatar da dalilin da abun ciki a cikin ruwa da kuma ƙasa

Sulfate ions ne salts na sulfuric acid matsakaici. Mutane da yawa daga cikin wadannan mahadi readily mai narkewa a cikin ruwa. Karkashin al'ada yanayi da abubuwa ne a cikin m jihar, da haske da launi. Mutane da yawa na sulfate ions da sedimentary asalin, su ne na marine da lacustrine sediments sinadaran.

tsarin fasali

A crystal tsarin izni wani Hadakar SO42- anions. Kamar yadda kowa mahadi za a iya gano divalent karfe sulfates. Alal misali, sulfate ions ta hanyar hada da alli cations, barium, strontium, samar da insoluble salts. Wadannan sediments ne ma'adanai da zama a free jihar a yanayi.

Kasancewa a cikin ruwa

Bugu da ƙari, sulfate ion aka kafa a lokacin da gishiri dissociation, don haka da cewa irin wannan ions dauke a cikin surface ruwaye. Babban tushen irin wannan mahadi ne sunadarai matakai na hadawan abu da iskar shaka na sulfides da sulfur.

A gwaji yawa na sulphate ions shigar da kududdufai a withering rayayyun kwayoyin halitta hadawan abu da iskar shaka terrestrial da kuma na cikin ruwa shuka halittu. Bugu da kari, su ne a karkashin kasa drains.

The adadin sulfate ion generated a masana'antu da aikin gona da effluents.

Halin da low-mineralized ruwa SO42- ions. Akwai ci siffofin irin wannan mahadi, wanda gaskiya ma shafi na gwargwado na ruwan sha. Alal misali, magnesium sulfate ne insoluble fili cewa accumulates a cikin ruwa.

The darajar a sulfur sake zagayowar

Idan muka bincika da sulfate ion a ruwa, shi ne dole a lura da muhimmancin da cikakken sake zagayowar a cikin yanayin sulfur da mahadi. Saboda daga kufan sulfate-rage kwayoyin cuta, ba tare da samun damar daga iska oxygen, shi ne ta rage zuwa hydrogen sulfide da sulfides. Saboda gaban oxygen a cikin ƙasa ruwa ne da za'ayi maimaita hira daga cikin wadannan abubuwa a cikin sulphates.

A karkashin mataki na sulphate-rage kwayoyin cuta a cikin rashi na oxygen an rage wa sulphides da hydrogen sulphide. Amma da zaran ruwa ya zo a cikin halitta oxygen, kuma oxidized zuwa sulfate.

The tara ruwan sama SO42- ion maida hankali ne 10 MG da cubic decimetre. Ga ruwa tare da wannan adadi ne game da 50 MG da DM ^3. A karkashin kasa kafofin gwada yawa sulfate abun ciki shi ne ma mafi girma.

Domin surface ruwa ne halayyar da dangantaka tsakanin lokaci na shekara da kuma yawan sulfuric acid ions. Bugu da kari, da gwada yawa awo rinjayar ayyukan mutane, Munã rage da oxidizing matakai abin da ke faruwa a yanayi.

Sakamako a kan ruwa ingancin

Sulfates da wani gagarumin tasiri a kan ingancin ruwan sha. Su ƙãra taro adversely rinjayar da organoleptic halaye. Ruwa zama m dandano, ta ƙara ta turbidity. Dagagge matakan wadannan anions adversely rinjayar da physiological matakai a cikin jikin mutum. Suna talauci tunawa a cikin jini daga hanji. A mafi girma yawa da suka nuna a laxative sakamako, rushe narkewa kamar tafiyar matakai.

Yana iya kafa wani mummunan tasiri na sulfates a kan gashi, irritating da mucous membrane da idanu da kuma fata. Saboda hatsarin da cewa suna wakiltar ga jikin mutum, shi ne muhimmanci a ƙayyade sulfate ions, ya dauki dace matakan rage yawa a cikin ruwan sha. Bisa ga matsayin dole ba wuce 500 MG da cubic decimetre.

Musamman tabbatar da dalilin da anions a ruwa

A dakin gwaje-gwaje karatu dogara ne ingantaccen dauki ga sulfate ion da Trilon B. Titration ne da za'ayi a cewar Gost 31940-12 sa ga SO42-. Ga awon gwaje-gwajen, da abun ciki alaka da katin shaida na sulfate anions a cikin ruwan sha da kuma sharar gida da ruwa, shirya mafita daga barium chloride a daidan maida hankali (0.025 mol, da DM ^3). Bugu da kari, analysis bukatar mafita: magnesium salts, ammonium buffer, Trilon B, azurfa nitrate, nuna alama eryochrom T baki.

A algorithm a cikin bincike

Laboratory yana amfani da wani conical flask da ciwon damar game da 250 ml. Yana da aka yi da pipetting 10 ml na wani magnesium gishiri bayani. Bugu da ari, bincikar flask aka kara 90 ml na distilled ruwa, 5 ml na ammonia buffer bayani, 'yan saukad da wani nuna alama, titration ne da za'ayi amfani da wani bayani da EDTA disodium gishiri. A tsari ne da za'ayi har akwai wani canji a cikin launi blue tare da ja da shunayya.

Next, ƙayyade yawan EDTA disodium gishiri bayani, wanda ake bukata domin titration. Don samun dogara da sakamakon, shi ne kyawawa su maimaita hanya 3-4 sau. Amfani da gyara coefficient, da lissafi aka yi gwada yawa abun ciki na sulfate anions.

Features shiri na samfurori bincikar ta titration

Aiwatar da lokaci daya da bincike na biyu samfurori da ciwon girma na 100 ml. Wajibi ne a dauki wani conical flask, lasafta ta 250 ml. A kowane daga cikinsu da ke sa a dakin gwaje-gwaje 100 ml na bincike samfurin. Sun kara 2-3 saukad da na mayar da hankali hydrochloric acid, 25 ml na barium chloride, sa kurtun a waterbath. Dumama aka za'ayi domin minti 10, sa'an nan da bincikar samfurin ya kamata a bar for 60 minutes.

Sa'an nan, a tacewa samfurori haka cewa tace aka ba precipitate barium sulfate. Da tace aka wanke da distilled ruwa, da mafita da aka bari by babu chloride ions. Don yin wannan lokaci-lokaci ingantaccen dauki tare da azurfa nitrate bayani. Idan ka gan wani hazo, shi ya nuna gaban chloride.

Da tace an sa'an nan sanya a cikin wani flask, inda shaida da aka gudanar. Bayan Bugu da kari na 5 ml na ammonia ta girgiza abinda ke ciki na flask tare da gilashin sanda, da tace fãta shimfiɗaɗɗa, mike tare da kasa. Per 5 MG na bincikar ions suna kara da cewa da ruwa 6 ml disodium EDTA. Da abinda ke ciki aka kona a cikin wani ruwa mai wanka, sa'an nan a mai tsanani a kan wani hotplate har sai da cikakken rushe precipitate, abin da yake a cikin ruwa tare da tace.

Dumama lokaci kada wuce minti biyar. Don inganta ingancin da bincike ne dole lokaci zuwa lokaci, mõtsar da abinda ke ciki na flask tare da gilashin sanda.
