    六、剖析办法
    VI. Analysis Methods

    (一) Cu(铜)
    (I) Cu

    1. 步调
    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

    (7) Continue to titrate the solution to ivory with 0.1N Na2S2O3

    2. 盘算
    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

    2. 盘算
    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
    剖析补加公式:补加物料207B(L) :(尺度值—剖析值)×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
