Preparation of non-aqueous solution in carbon sulfur analyzer
Titration solution: A solution: take iodine with a balance, 2G in the beaker, add a small amount of distilled water, called potassium iodide 20g, add in batches to dissolve all the iodine. B solution: weigh the starch 2G with a balance and mix it with a little water. Pour into the boiling distilled water, 100ml, and continue to boil for 2-3 minutes to cool. Mix A, B, two solutions, dilute with distilled water to 5000ML, shake well. Of course, the proportion is to operate according to this, the solution reagent configuration how much, we can own conversion.
Tank solution: solid absorption: 1000ml distilled water 0.2g Koh, a small amount of Methyl Red mixed solution, shake well. (green alkaline solution)
Leveling bottle solution: adding 6ml concentrated sulfuric acid to each 600ml distilled water. After adding this water, observe whether the water in front of the measuring cylinder is in zero scale. To zero scale.
