六、分析方法
VI. Analysis Methods
(一) Cu(銅)
(I) Cu
1. 步驟
1. Steps
(1). 取25mL Sample，加40mL(20%)H2SO4
(1) Take 25mL Sample, add 40mL(20%)H2SO4
(2). 加0.5g氨基磺酸加熱煮沸1min,冷卻 5 分鐘
(2) Add 0.5g sulfamic acid and heat the solution to boiling, keep it boiling for 1min, and cool down for 5min.
(3). 加2g KI攪拌3分鐘
(3) Add 2g KI, mix for 3 min.
(4). 以0.1N Na2S2O3 滴定至淡黃色
(4) Titrate the solution to light yellow with 0.1N Na2S2O3
(5). 加5mL淀粉(Starch)指示劑
(5) Add 5mL Starch indicator
(6). 加20mL 10% KSCN
(6) Add 20mL of 10% KSCN
(7). 繼續(xù)以0.1N Na2S2O3 滴定至乳白色
(7) Continue to titrate the solution to ivory with 0.1N Na2S2O3
2. 計(jì)算
2. Calculation
Cu(g/L) = N of Na2S2O3×mLs of Na2S2O3×63.54÷25
例 eg. : 2.9g/L = 0.1N×11.4mL×63.54÷25
3. 分析補(bǔ)加公式
3. Adding formula analysis
補(bǔ)加物料207A/B(L):(標(biāo)準(zhǔn)值—分析值)×槽積/ 29

(5). 加入25mL 1M Na2SO3,攪拌5min
(5) Add 25mL 1M Na2SO3, mix for 5min
(6). 以0.1N HCl標(biāo)準(zhǔn)液滴定至pH10 ---- B mLs (HCHO含量)
(6) Titrate the solution to pH10 ----B mLs (HCHO content) with 0.1N HCl standard solution
2. 計(jì)算

例 eg : 12(g/L) = 0.1N×15mL×40÷5
分析補(bǔ)加公式:補(bǔ)加物料207B(L) :(標(biāo)準(zhǔn)值—分析值)×槽積/340
