Ukungenisa

Leli sonto lithengiswa ngokusebenzisa isenzo sokuhlanganisa i-sodium silicate ngezinkanyezi (njengohayidrokhlorikhi, isafureyikhi asidi, kanye nezinsimbi (okudingekayo i-ammonium chloride, i-ammonium sulfate, kanye ne-ammonium bicarbonate). Lolu hlahlo lusebenza ngokuthi kuhlambulule isilika esikhathini esisodwa, olusebenza njengesilika esikhanyisiwe. Emva kwalokho, isilika sihlanziswa ngamanzi ukuze kususwe izimpawu, futhi sivulelwe ukuze sikwazi ukuthola leli sonto elikhokhelwe. Kusukela kwezinsimbi ezithambileyo, isilinganiso somzimba wasekhethweni akusekho kungaphezu kwe-99.0%.

[Izinhlelo] Leli sonto lingumlozana omhlophe, oluhluvu.
Leli sonto luhlambulula kwi-solushini somthombo we-sodium hydroxide ohlelweni, kodwa aluhlambululi kwi-amanzi noma kwi-hayidrokhlorikhi enothile.
[Ukubonakala] Thola ngaphezu kwe-5mg yeleli sonto, faka kwi-platinum crucible, faka 200mg yekhawundiboni yekhawundiboni, hlambulula kwi-600-700℃ ngemizuzu emishumi, sula, faka 2ml yamanzi futhi vutha ukuze kuhlambulule, faka ngokuhlela 2ml yezamaniyamu yekhawundiboni yekhawundiboni (thola 6.5g yemolybdenum acid, faka 14ml yamanzi kanye ne-14.5ml yezamaniyamu yehayidrokhlorikhi enothile, hlambulula ukuze kuhlambulule, faka kwi-mixture ehlakaniphile yamanzi e-32ml yehayidrokhlorikhi kanye ne-40ml yamanzi ngokuhlanganisa, vumela ukuthi kube khona ngemizuzu emihlanu, filitsha, thola ifilitrathi, futhi uhlola okwenzekile) 2ml, isolushini siyavakasha esikhahlelwe.
[Ukuhlola] Ubukhulu bomphumela: Thola 10g yeleli sonto futhi hlola ngokwesimo nokuhlola ubukhulu bomphumela [General Rule 0982, Isimo 2 (1)]. Isimo somsebenzi esithola ngaphansi kwe-sieve No. 7 (125μm) akusekho kungaphezu kwe-85%.
Ukucabanga nokucabanga: Thola 1g yeleli sonto, faka 20ml yamanzi, hlanganisa kahle, filitsha, futhi thola ifilitrathi elilandelayo. Hlola ngokwesimo (General Rule 0631), futhi isimo som-pH kumele kube phakathi kwe-5.0 kanye ne-7.5.
Chloride: Thola 0.5g yeleli sonto, faka 50ml yamanzi, vutha futhi vutha ngokuhlela ngemizuzu emibili, sula, faka amanzi ukuze kube kwi-50ml, hlanganisa kahle, filitsha, thola 10ml yefilitrate ephakathi, hlambulula ngokwesimo (General Rule 0801), futhi linganisele nesolushini sokwakhiwa okuphathelene nokuyayeka kwe-sodium chloride esisodwa. Akusekho okuphakathi (0.1%).
Sulfate: Thola 10ml yefilitrate etholakalayo kusuka kumsebenzi wokuhlanganisa i-chloride, faka umsebenzi ngokwesimo (General Rule 0802). Linganisele nayo nesolushini sokwakhiwa okuphathelene nokuyayeka kwe-potassium sulfate esikhathini esisodwa. Isilinganiso somsebenzi wokuhlambulula akusekho okuphakathi kwesolushini sokwakhiwa nesolushini sokwakhiwa (0.5%).
Loss on drying: Thola leli sonto futhi lithwalela kwi-145℃ ngemizuzu emibili. Ukuphela kwezinsimbi akusekho ngaphezu kwe-5.0% (General Rule 0831).
Loss on ignition: Thola 1.0g yefomula yokuhlambulula etholakalayo phakathi kwezinto zokuphela kwezinsimbi, vula ngokuphathelene, faka kwi-1000℃ ngemizuzu emibili. Ukuphela kwezinsimbi akusekho ngaphezu kwe-8.5% kwezinsimbi ezithambileyo.
Iron salt: Thola 0.2g yeleli sonto, faka 25ml yamanzi, 2ml yehayidrokhlorikhi, futhi 5 imidwebo yehayidrokhlorikhi, vula ngokuphathelene, vutha ngemizuzu emihlanu, vutha, filitsha, nquma ifilitrathi ngokusezingeni elincane zemanzamnyama, hlanganisa ifilitrathi kanye nokuhlambulula, faka 50mg yezinsimbi yezamaniyamu persulfate, vula ngamanzi kuya kwi-35ml, hlolela ngokwesimo (General Rule 0807), linganisele nesolushini sokwakhiwa kusukela kwi-3.0ml yezamaniyamu yezinsimbi esisodwa. Akusekho okuphakathi (0.015%).
Heavy metals: Thola 3.3g yeleli sonto, faka 40ml yamanzi kanye ne-5ml yehayidrokhlorikhi, vutha ngokuhlela futhi vutha ngemizuzu emashumi amabili, vutha, filitsha, futhi vula ifilitrathi kwi-100ml iflaski yezinsimbi. Hlambulula ifilitrathi ngokusezingeni elincane zemanzamnyama, futhi faka izinsimbi zokuhlambulula kwi-volumetric flaski. Hlambulula ngamanzi kuya kwi-makhi, thwala isibonelo soku-phenolphthalein, faka isibonelo soku-amoniya ngokwesikhathi sokuthi sibe siphakathi, faka 2ml yezamaniyamu yezinsimbi yasekhethweni (pH3.5) kanye nezinsimbi ezithile zemanzamnyama ukuze kube yiziphi eziningi kwi-25ml, futhi hlambulula ngokwesimo (General Rule 0821, Isimo 1). Isilinganiso somzimba omkhulu akusekho ngaphezu kwe-30 parts kumililili.
