1. Tātarihia te wairewa pati ia ra, whakatauhia te kukū o te waikawa pungatara kore utu, te pūkawa pūkawa ngāwha, te nika pūkawa ngāwha me te waikawa katoa, ka whakakī i te wā.
2. Ko te tauine tāpiri o te pūkawa ngāwha pūkawa ki te Sn&Ni Tote Electrolytic Tae tāpiri he 1:1.1~1.2.
3. Ka puta nga rerenga ma i roto i te wa roa e whakaputa ana, na reira me tarai te wairewa pati me te horoi i nga wa katoa.
kua hiritia ki te peeke, 5kg kupenga mo ia me nga peeke 4 ki te kaata, 20kg kupenga ia.Ka tiakina mai i te marama i te waahi maroke.
Te whakatau i te ihirangi stannous sulfate (SnSO4).
Reagents e hiahiatia ana
①1% otinga māngaro ② 0.1N wairewa paerewa iodine
Nga mahi whakamatautau
Toia tika te 10mL o te wairewa whakamatautau ki roto i te ipurau tapatoru 250mL, tāpirihia te 100mL wai, tāpirihia te 5mL o te 1:1 waikawa pūhaumāota, kātahi ka tāpirihia te 5mL o te 1% tohu māngaro, tere te tiriti ki te wairewa paerewa 0.1N iodine, ka huri te otinga mai i kore tae ki te kahurangi Ko te tae te pito mutunga, ka tuhia te rōrahi V o te otinga paerewa kua pau.

Te pūkawa pūkawa (g/L)=10.73 × V × N
Te whakatau i te ihirangi nickel sulfate (NiSO4).
Reagents e hiahiatia ana
①30% hauwai hauwai
②10% pāhare pāporo konutai tartrate
③ 1:1 wai haukini
④1% amine waikawa purpuric
2. Nga mahi whakamatautau
Tangohia 1mL o te wairewa pati tae ki roto ki te ipu koeko tapatoru 250mL, tāpirihia te 2mL (30%) hauwai peroxide, whakamahana ki te maroke tata, tāpirihia te 80mL wai i muri i te whakamahana, 10mL (10%) konutai konutai tartrate, 20mL (1:1) haukini. wai, He iti te 1% te haukinia purpurate i titrated ki te otinga paerewa 0.01N EDTA tae noa ki te huri papura te otinga hei pito mutunga.

Nickel sulfate (g/L)=262.9 × V × N Te whakatau o te waikawa katoa (H, SO)
1. Reagents e hiahiatia ana
0.1% Bromothymol Blue
② 1NNaOH otinga paerewa 2. Nga hikoinga whakamatautau
Toia tika te 10mL o te wairewa whakamatautau ki roto i te ipurau tapatoru 250mL, ka tapirihia te 100mL wai.Taapirihia kia 4 nga pata o te tohu kahurangi bromothymol 0.1%, whakatairite ki te otinga paerewa 1N NaOH, huri mai i te kowhai ki te cyan hei pito mutunga, ka tuhia te rōrahi V o te NaOH i pau.
3. Tātaihia te tapeke waikawa (
g/L)=4.9xVxN
Totohu tae Champagne 2 -- tikanga whakamatautau
Te whakatau i te waikawa kore (H2SO4)
Reagents e hiahiatia ana 1N NaOH otinga paerewa
2. Nga mahi whakamatautau
Me tuhi tika te 50mL o te wairewa whakamatautau ki roto i te ipurau 100mL, whakatairitehia te pH ki te 2.1 me te otinga paerewa NaOH 1N i raro i te inenga o te mita waikawa, ka tuhi i te ruri V kua pau.
