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). 繼續以0.1N Na2S2O3 滴定至乳白色
(7) Continue to titrate the solution to ivory with 0.1N Na2S2O3

2. 計算
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. 分析補加公式
3. Adding formula analysis
補加物料207A/B(L):(標準值—分析值)×槽積/ 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

步驟
1. Steps

Note : 1M Na2SO3須先利用0.1N NaOH 調至pH=10
Note : The PH of 1M Na2SO3 shall be adjusted to 10 with 0.1N NaOH
(1). 取5mL Sample于燒杯中加100L去離子水
(1) Take 5mL Sample into a beaker, and add 100L deionized water
(2). 沖洗電極放入Sample
(2) Wash the electrode, and put them into the Sample
(3). 以0.1N HCl標準液滴定至 pH10.2 ---- A mLs (NaOH含量)
(3) Titrate the solution to pH10.2 ---- A mLs (NaOH content) with 0.1N HCl standard solution
(4). 繼續以0.1N HCl調至pH10
(4) Continue to titrate with 0.1N HCl until the PH is 10
(5). 加入25mL 1M Na2SO3,攪拌5min
(5) Add 25mL 1M Na2SO3, mix for 5min
(6). 以0.1N HCl標準液滴定至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
分析補加公式:補加物料207B(L) :(標準值—分析值)×槽積/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
析補加公式: 補加物料207C(L) :(標準值—分析值)×槽積 /400 Adding formula analysis: Added material 207C(L): (standard value-analysis value) ×volume of the tank/400

七、廢水處理
VII. Wastwater Treatment

   加入1%體積比的甲醛,15克/L的硫酸亞鐵,加熱到70℃直到溶液分解,使銅沉淀出來為止。
  Add methanal with 1% volume ratio, 15g/L FeSO4, heat to 70℃, until the solution is pyrolyzed, and Cu deposites.
