INickel sulfamate concentrate
Nickel sulfamate is a main salt of nickel plating which has developed rapidly in the world in recent years.因其內應力低,沉積速度快,而在汽車、摩托車、冶金、電子、鎳網、鋁合金等行業得到了廣泛應用.該工藝最關鍵之處是Nickel sulfamate concentrate(NICKEL SULFAMATE SOLUTION)of高純度;在嚴格控制條件下生產ofNickel sulfamate concentrate無需任何添加劑就能產生低應力之鍍層;如配合添加劑of使用,則能得到外觀更佳,內應力更低of鍍層

IITest items and analysis methods of nickel sulfamate solution
1.proportion:用proportion計測定(1.550-1.556)
two.PH值:酸度計測定(ding)
three.雜(za)質含(han)量(Fe,Pb,Cu,Zn,Ca,Mn):AA測定
4. Determination of nickel content
1)在室溫two0℃When, remove10ml樣品放于100ml容量瓶中,用DI水稀釋至刻度,取上述稀釋液10ml放于two50ml錐形瓶中;
two)在錐形瓶(ping)(ping)中加(jia)入約15ml濃氨(an)水(分析純),加(jia)入50ml去離子水,再加(jia)入0.twog紫脲酸銨(an)(固體(ti))指示劑放于瓶(ping)(ping)中搖勻;
three)用0.1MofTitrate EDTA standard solution until the solution is purple.
4) Calculation: nickel content (g / L) = 5.869 × VEDTA
VEDTA………滴定(ding)所用(yong)ofEDTA標(biao)準溶液of體(ti)(ti)積,mL
5.Sulfate radical濃度of測定
1)用(yong)10ml量筒移(yi)取(qu)100ml氨基磺酸鎳溶液樣品于500ml燒杯中,用(yong)170ml去(qu)離子水稀釋(shi)樣品,再加入three5ml 0.1MBaCltwo溶液;
two)用(yong)攪拌(ban)磁子,在加熱攪拌(ban)器上攪拌(ban)15分鐘(zhong),溫(wen)度設定(ding)70℃,如果(guo)看不(bu)到沉淀(dian)出現,則原(yuan)溶液ofSulfate radical濃度小于two0ppm;
three)將上(shang)述溶液(ye)靜置陳(chen)化過夜;
4)取(qu)潔凈of玻璃砂芯漏斗(dou),在洪箱(xiang)中(80℃)Dry for half an hour, cool and weigh accurately to the nearest0.0001g——M1(g);
5)小心地傾去上層清液,用玻璃砂芯漏(lou)斗過濾沉(chen)淀(dian),沉(chen)淀(dian)應為亮白色(如果是黃色,則用少量of5-10%稀鹽酸洗滌沉(chen)淀(dian)),用去離子(zi)水徹底清洗沉(chen)淀(dian);
6) Put the glass sand core funnel and precipitate into the oven for 80 minutes℃,two小時,使沉淀完全干燥,準確稱其重量,精確到0.0001g——Mtwo(g);
7)計算: 溶液中Sulfate radicalof濃(nong)度(du)(ppm)為a
? a=1threetwotwo.9(Mtwo-M1)×two
**SO4(Mtwo-M1)×10/BaSO4×100×1.555
Ammonium concentration in nickel sulfamate solutionppm為c,固體氨基磺酸中Sulfate radical濃度ppm為b,
c=0.1875(a-0.three85b)
