六、分析方法
VI. Analysis Methods
(一) Cu(铜)
(I) Cu
1. 步骤
1. Steps
(1). 取25mL Sample，加40mL(20%)H2SO4
(1) Take 25mL Sample, add 40mL(20%)H2SO4
(2). 加0.5g氨基磺酸加热煮沸1min,冷却 5 分钟
(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搅拌3分钟
(3) Add 2g KI, mix for 3 min.
(4). 以0.1N Na2S2O3 滴定至淡黄色
(4) Titrate the solution to light yellow with 0.1N Na2S2O3
(5). 加5mL淀粉(Starch)指示剂
(5) Add 5mL Starch indicator
(6). 加20mL 10% KSCN
(6) Add 20mL of 10% KSCN
(7). 继续以0.1N Na2S2O3 滴定至乳白色
(7) Continue to titrate the solution to ivory with 0.1N Na2S2O3
2. 计算
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. 分析补加公式
3. Adding formula analysis
补加物料207A/B(L):(标准值—分析值)×槽积/ 29
Added material 207A/B(L): (standard value-analysis value) ×volume of the tank/29
(二) NaOH&HCHO分析法
(II) NaOH&HCHO analysis method
步骤
1. Steps
Note : 1M Na2SO3须先利用0.1N NaOH 调至pH=10
Note : The PH of 1M Na2SO3 shall be adjusted to 10 with 0.1N NaOH
(1). 取5mL Sample于烧杯中加100L去离子水
(1) Take 5mL Sample into a beaker, and add 100L deionized water
(2). 冲洗电极放入Sample
(2) Wash the electrode, and put them into the Sample
(3). 以0.1N HCl标准液滴定至 pH10.2 ---- A mLs (NaOH含量)

(4). 继续以0.1N HCl调至pH10
(4) Continue to titrate with 0.1N HCl until the PH is 10
(5). 加入25mL 1M Na2SO3,搅拌5min
(5) Add 25mL 1M Na2SO3, mix for 5min
(6). 以0.1N HCl标准液滴定至pH10 ---- B mLs (HCHO含量)

2. 计算
2. Calculation
(1) NaOH (g/L) = N of HCl×A mLs of HCl ×40÷5
例 eg : 12(g/L) = 0.1N×15mL×40÷5
分析补加公式:补加物料207B(L) :(标准值—分析值)×槽积/340
Adding formula analysis: Added material 207B(L): (standard value-analysis value) ×volume of the tank/340
(2) HCHO (g/L) = B mLs of HCl×N of HCl×30÷5
例 eg : 5(g/L) = 0.1N×8.3mL×30÷5
