Cov Kev Zoo ntawm Kev Siv Tshuab ntawm Sustar Copper Sulfate 1

Kev tshuaj xyuas cov khoom siv raw

Sustartooj liab sulfate

1. Cov khoom siv raw yuav tswj cov chloride ion, acidity. Nws muaj tsawg dua impurities

2.Cu≥25%. Cov ntsiab lus siab dua

Lwm yam tooj liab sulfate

1. Yog tias cov ntsiab lus ntawm chloride ion thiab acidity ntawm cov khoom siv raw thaum ntxov tsis raug tswj hwm nruj me ntsis, kev tiv thaiv kev sib sau ua ke ntawm silica yuav tsum tau ntxiv rau theem tom qab.

2. Thaum cov khoom no raug ntxiv rau hauv cov khoom sib xyaw ua ntej tom qab, nws tseem yuav ua rau muaj kev hloov pauv thiab ua rau cov khoom sib xyaw ua ntej vim nws muaj cov khoom tsis huv siab. Tsis tas li ntawd, yog tias cov silica sib xyaw tsis sib xws, kev sib sau ua ke yuav tshwm sim.

Kev tshuaj ntsuam hom crystalline

Sustartooj liab sulfate

Hom khoom me me puag ncig. Hom siv lead ua no tsis yooj yim raug rhuav tshem. Thaum lub sijhawm ua kom sov thiab ziab, muaj qhov chaw nruab nrab ntawm lawv, nrog kev sib txhuam tsawg dua, thiab kev sib sau ua ke qeeb qeeb.

Lwm yam tooj liab sulfate

Hom koob los yog hom duab plaub fab. Qhov sib txawv loj ua rau muaj kev sib tsoo ntawm cov khoom siv.

Cov txheej txheem cua sov

Sustartooj liab sulfate

Kev ua kom sov thiab ziab tsis ncaj qha: ziab tsis ncaj qha los ntawm cua kub ntshiab kom tsis txhob muaj kev sib cuag ncaj qha ntawm nplaim taws nrog cov ntaub ntawv thiab tiv thaiv kev ntxiv cov tshuaj lom neeg.

Lwm yam tooj liab sulfate

Nrog rau kev cua sov ncaj qha, qee cov tshuaj lom neeg xws li sulfide thiab cov tshauv thee seem yuav nkag mus rau hauv cov khoom, cov khoom yuav tig daj thiab cov ntsiab lus sulfide yuav siab dhau.

Kev tswj cov dej noo

Sustartooj liab sulfate

1. Tooj liab sulfate pentahydrate ruaj khov heev nyob rau hauv qhov kub thiab txias ib txwm muaj, thiab tsis yaj. Tsuav yog muaj tsib dej siv lead ua, tooj liab sulfate yuav ruaj khov. (Xam los ntawm CuSO4 · 5H2O) Cov ntsiab lus tooj liab sulfate ≥96%, muaj 2% - 4% dej dawb. Cov khoom tsuas yog sib xyaw nrog lwm cov khoom noj pub lossis cov khoom noj raw tom qab ziab ntxiv kom tshem tawm cov dej dawb, txwv tsis pub cov khoom noj zoo yuav raug cuam tshuam vim muaj dej ntau.

2. Txoj kev tshawb nrhiav dej noo tshwj xeeb ntawm Sustar (saib Cov Lus Qhia Ntxiv)

Lwm yam tooj liab sulfate

Yog tias ntxiv cov pa roj carbon dub dawb, nws yuav tsum tau ziab ntawm qhov kub siab, dej dawb raug tshem tawm hauv zos, cov qauv siv lead ua puas tsuaj, thiab cov khoom yooj yim nqus cov dej noo.

Txoj Kev Tshawb Nrhiav Dej Ntxias Tshwj Xeeb ntawm Sustar

Tshuaj Reagent

Acetone: tshuaj lom neeg ntshiab

Cov Cuab Yeej thiab Cov Khoom Siv

Iav xuab zeb Crucible: qhov qhib 5-15 μm.

Qhov cub hluav taws xob ziab: qhov kub thiab txias tswj tau yog 50 ± 2 ℃.

Tus neeg qhuav: siv calcium chloride (tus neeg sawv cev ziab) lossis allochroic silica gel ua tus neeg qhuav.

Cov kauj ruam txheeb xyuas

Hnyav li 2g ntawm cov qauv (raug rau 0.0002g), muab tso rau hauv lub khob iav xuab zeb nrog qhov hnyav tas li ntawm (50 ± 2) ℃, ntxiv 5ml acetone. Do nrog ib tug pas nrig zoo thiab lim, ntxuav nws nrog acetone ob zaug nrog 5ml txhua zaus. Muab lub crucible thiab cov qauv kuaj tso rau hauv chav tsev qhov chaw cua txias rau 10 feeb, tom qab ntawd xa mus rau qhov cub ntawm (50 ± 2) ℃ rau ziab rau 2 teev, txias lawv hauv lub tshuab ziab rau 20 feeb, thiab hnyav lawv (raug rau 0.0002g).

Kev suav cov txiaj ntsig

Cov dej hauv feem pua ntawm qhov hnyav, xam raws li cov mis (4): X₁=(m₁-m₂)/m*100

M1 - qhov hnyav ntawm cov qauv thiab lub khob iav xuab zeb, (g)

M2 - qhov hnyav ntawm cov qauv thiab cov xuab zeb iav tom qab ziab, (g)

M - qhov hnyav ntawm cov qauv kuaj, (g)

Siv qhov nruab nrab ntawm cov txiaj ntsig ntawm kev xeem sib luag ua cov txiaj ntsig ntawm kev xeem, thiab qhov sib txawv kiag li ntawm cov txiaj ntsig ntawm kev xeem sib luag.
