四、Tank liquor maintain ：
1.Using the same concentration of liquid to supplement the daily consumption level；
2. Add LT – 601 according to the analysis of the solution concentration, maintaining the solution equivalent concentration and pH;
3. Add 0.8liter LT – 601 after produce 100m2 plates;
4. Need to change the slot when the solution copper ion concentration is 1 g / liter or a liter fluid production is about 20m2.
五、 Analysis Method：
1．Analysis of LT-601：
a、 Using a transferring tubeto get 1 ml to 250 ml conical liquid bottle, add 100ml water and 4 drops of methyl orange indicator;
b、 Using droplets 0.1N HCl standards set to end at the red, a few milliliters of titration V;
c、Calculate ：LT-601（V/V）=V×0.1×0.25
2． copper ion:
a、 Using a transferring tube to get 1 ml to 250 ml conical liquid bottle, add 100ml water;
b、Add 40ml acid, 2 - 3 drops PAN indicator;
c、 Using 0.1N EDTA standard droplets to violet to the end, the number of titration ml V;
d、Calculation: copper ion (g / L) = 0.64 × V |
